The 130th Engineer Brigade is a subordinate unit of the 8th Theater Sustainment Command which is in turn subordinate to United States Army Pacific . It provides engineering assistance to US forces stationed throughout the Pacific Ocean region . |
The Brigade 's Headquarters and Headquarters Company is stationed at Schofield Barracks and permanently commands two subordinate battalions . The 65th Engineer Battalion and the 84th Engineer Battalion are both located at Schofield Barracks . The total force of the brigade and its subordinate elements is approximately 1 @,@ 600 . As the brigade is modular in nature , it is able to take command and control of more units when deployed . |
= = History = = |
= = = Origins = = = |
The 130th Engineer Brigade traces its lineage to the 1303rd Engineer General Service Regiment which saw action in World War II . The regiment was activated on 15 July 1943 at Camp Ellis , Illinois . It was deployed to the European Theatre where it participated in the Battle of Normandy and subsequent invasion of Germany before being transferred to the Pacific after V @-@ E Day . The 1303rd received campaign streamers for Normandy , Northern France , Rhineland , Ardennes @-@ Alsace , Central Europe , and the Asian @-@ Pacific theatre . It was deactivated in Japan on 31 January 1946 . |
The regiment was re @-@ designated as Headquarters and Headquarters Company , 130th Engineer Aviation Brigade in Japan on 8 July 1955 before being activated in September of that year . Only a few months later , this brigade was inactivated on 25 June 1956 without having seen any deployment . |
On 16 June 1969 , Headquarters and Headquarters Company , 130th Engineer Aviation Brigade was re @-@ designated as Headquarters and Headquarters Company , 130th Engineer Brigade and activated in Pioneer Kaserne , Hanau , Germany . The 130th Engineer Brigade was a consolidation of V Corps ' 37th and 11th Engineer Groups into a single unit that would provide more efficient command and control . It was subsequently put under the command of V Corps , as part of the US Army 's force in Europe . The brigade received its shoulder sleeve insignia on 23 September 1969 , and its distinctive unit insignia on 3 November 1969 . Brigade members specially designed these with images alluding to the 1303rd Regiment 's battle honors in World War II using scarlet and white , colors signifying US Army engineer units . |
The brigade remained in Germany in support of V Corps for almost 25 years , seeing no deployments . It underwent a shuffling of units as several of its battalions were reassigned elsewhere following the end of the Cold War in 1990 , and it gained new battalions from units deactivating elsewhere . Though three of the brigade 's subordinate battalions deployed to support Operation Desert Shield and Operation Desert Storm , the brigade headquarters itself remained in Germany along with the rest of V Corps . The operations were conducted by VII Corps and XVIII Airborne Corps , which had significant engineer assets of their own . Throughout the early 1990s , the brigade would continue to see units come and go from its command as they were transferred from the restructuring 18th Engineer Brigade and the deactivating 7th Engineer Brigade . |
= = = Operation Joint Endeavour = = = |
From December 1995 to January 1996 , all units in the brigade , except the 320th Engineer Company ( Topographic ) , deployed to Croatia or Bosnia and Herzegovina in support of Operation Joint Endeavor . The 320th Engineer Company deployed their topographic surveying platoon the following year . The 130th Engineer Brigade was tasked with building an assault bridge over the Sava River . Despite severe flooding conditions around the river and international pressure against such a structure , the brigade sent its units to begin work on the bridge . In December 1995 , the 502nd Engineer Company deployed to Zupanja , Croatia and placed the historic ribbon bridge over the river . This bridge , at 2 @,@ 239 feet ( 682 m ) was the longest assault floating bridge in military history . The company operated 24 @-@ hours a day for three months crossing critical traffic in support of Task Force Eagle and NATO 's Implementation Force . The company also assisted in the construction of a second bridge over the Sava River in Brčko @-@ Gunja . The 502nd Engineer Company redeployed in May 1996 , with a rafting section remaining at Slavonski Brod to support the force restructuring of Task Force Eagle . The 130th Engineer Brigade would go on to construct seven fixed bridges in support of the operation . During the deployment , the brigade was also tasked with creating and maintaining maps and overlays of the area of operations . It would produce over 300 @,@ 000 such maps . The 130th Engineer Brigade was also tasked with repairing and maintaining much of the Task Force 's infrastructure . |
The brigade returned to Germany after the operation was complete . Throughout 1998 – 2002 it would train with German engineers , including German units from Lahnstein and Speyer , as well as the German Engineering School . The brigade also set up marksman competitions with German units , to give US soldiers the chance to earn the German Armed Forces Badge of Marksmanship , the German Sports Badge , and other badges . Over 2 @,@ 500 of these badges would be earned by soldiers of the 130th over the years that it served in Germany . It also trained extensively in bridging operations at rivers throughout Germany . In summer of 2000 , the brigade participated in a joint engineering exercise in Moldova with US Navy Seabees and the 505th Engineer Brigade of the North Carolina Army National Guard . The exercise was the first ever conducted in Moldova and featured numerous training scenarios as well as the construction of a medical clinic . Several other such exercises were conducted in nations throughout Europe including Albania , Romania , Georgia , Latvia , Bulgaria and Macedonia . They also performed annual humanitarian missions to Poland , working on community projects around the country with the assistance of Polish Armed Forces every September , as a training exercise . |
= = = Operation Iraqi Freedom = = = |
The 130th Engineer Brigade mobilized in support of the Global War on Terrorism in 2003 . It was commanded by Colonel Gregg F. Martin . As preparations were being made for Operation Iraqi Freedom , the 130th Engineer Brigade was placed in charge of the largest engineering force in the theater . This included seven different engineering battalions as well as several separate group and company sized elements . Units of the brigade were then deployed to Kuwait in early 2003 , along with much of V Corps ' staff . They would provide command and assistance for the 3rd Infantry Division , 82nd Airborne Division and 101st Airborne Division as they crossed the border to Iraq and attacked to the capitol region of Baghdad from the south . Coupled with the landings of the 173rd Airborne Brigade Combat Team to the north , the operation would see the US Forces surround and destroy Iraqi forces in and around the capitol . |
The first obstacle facing the brigade was " the berm " , a 10 @-@ kilometer @-@ deep defensive obstacle complex that spanned Iraq 's border with Kuwait . The berm consisted of large tank ditches , berms of dirt , electrified fencing , and razor wire . It was decided that the 3rd Infantry Division 's Brigade Combat Teams would breach this berm in eight locations and move through . The 130th Engineer brigade analyzed the berms and provided a layout of them to coalition forces . The 130th Engineer Brigade then conducted the actual breaches in late March , using armored combat earthmovers to build roads for tracked vehicles , while armored vehicle @-@ launched bridges set up for wheeled vehicles . The 130th worked with Kuwati engineers to breach the berm in 12 places , and the 3rd Infantry Division 's Brigade Combat Teams moved though , starting the Iraq War . After combat forces moved through , the brigade and the Kuwatis then sealed off ten of these breaches to prevent Iraqi forces from using then , leaving two open for US forces that followed from the 82nd and 101st . |
After the breach , the 130th moved into Iraq . They provided support for the divisions as they advanced along the path to Baghdad . When a large sandstorm grounded aviation and large dust clouds became a problem , the brigade repurposed oil for use in dust abatement around airfields , allowing the 101st 's fleet of AH @-@ 64 Apaches to take off and engage Iraqi ground forces on 24 March . Retreating Iraqi units detonated many bridges to slow the 3rd Infantry Division 's advance . The 130th Engineers conducted rapid repairs to allow the brigades to continue to move through . The brigade supported combat elements moving through An Najaf , clearing roads and pathways of debris and obstacles to allow rapid movement through the city . The 565th Engineer Battalion built the " birthday bridge " – the longest float bridge constructed in a combat theatre with a span of 580 meters – over the Tigris River in Tikrit on Saddam Hussein ’ s birthday , 28 April 2003 . |
After the invasion was over , the brigade was supposed to support the operation with bridging and infrastructure support . During the planning for the invasion , the engineers of the brigade were told that reconstruction in Iraq would be conducted by Department of Defense contractors and Iraqi civilians . They were not originally prepared to conduct major reconstruction efforts . When V Corps became the commanding element for the task force to rebuild Iraq , much of the invasion force , including the 130th Engineer Brigade , was sent to do jobs they had not been originally planned for , as basic utilities and sanitation conditions in Iraq were far below what was expected . Throughout the rest of 2003 and 2004 , the engineers engaged in a large number of initial reconstruction projects on basic utilities , including schools , water treatment plants , waste removal , and the nation 's power grid . It was determined that the scale of these projects was much greater than what the US had expected or what had been encountered in previous contingencies . It was also decided that reconstruction was essential to the coalition since it would help win over the Iraqi people . By May 2003 , the brigade had been completely repurposed . Though originally tasked with demolishing obstacles , building fortifications , and bridging operations , the brigade was tasked entirely with construction projects . This conversion was a difficult process , as the brigade did not have the equipment and specialist units designed to handle reconstruction on a national scale . As more US military reconstruction units arrived in Iraq , the brigade grew to eight battalions and three groups . |
The 130th Engineer Brigade focused on bridging projects as was its specialty , but it ultimately found itself undertaking numerous different projects throughout the country for much of 2003 and into 2004 . Not all of its units were confined entirely to construction , though . The 502nd Engineer Company also conducted river patrol operations in Baghdad and Tikrit . This new mission for the company was essential for force protection , troop transportation , search and cordon operations , and to protect against sabotage on fixed bridges . In September 2003 , with the inactivation of the 38th Engineer Company ( Medium Girder Bridge ) , the 502nd Engineer Company became a multi @-@ role bridge company with both float and fixed bridging capabilities and the only active bridge company in USAREUR . |
The 130th was headquartered at Logistical Support Area Anaconda for the majority of the deployment . Throughout Operation Iraqi Freedom , the headquarters commanded up to 15 @,@ 000 engineers at one time , conducting missions including bridging , humanitarian assistance , topographic missions , dive missions , firefighting , base construction , river patrols , mine detection , missile removal and many more . Brigade units redeployed to Hanau in late 2003 and early 2004 . Most of the brigade 's soldiers returned to Hanau on 5 February 2004 after numerous logistical delays . Most of the 130th Engineer Brigade 's subordinate units would receive Meritorious Unit Commendation for their roles in the invasion of Iraq , though the Brigade 's headquarters did not . |
= = = Second tour in Iraq = = = |
The 502nd Engineer Company became the first V Corps company @-@ sized unit to return for a second tour in Iraq when it deployed in September 2004 . The company returned to Hanau in September 2005 . In December 2004 , the 130th Engineer Brigade 's headquarters was informed that it would be deployed back to Iraq the next year . The brigade mobilized and began this new deployment in September 2005 ; it began operating in the country the next month . The 54th Engineer Battalion followed in October . The brigade eventually replaced the 130th , 194th , and 20th Engineer Brigades , becoming the only engineer brigade operating in the country . By December 2006 , the brigade commanded all engineering formations in Multi @-@ National Corps - Iraq , including engineers from other branches of the US Military , for a total of 3 @,@ 300 soldiers . During the tour they were supported by the 412th Engineer Command . |
The 130th Engineers had a variety of reconstruction tasks during their second tour in Iraq . The top priority of the brigade was to " maintain and upgrade lines of communications " to " insure uninterrupted ground movement through the area of operations . " This duty also included detection and removal of Improvised Explosive Devices . The brigade undertook numerous construction projects , primarily in building coalition forward operating bases , but they were tasked with construction projects for the Iraqi army and civilians as well . Many of the units of the brigade were integrated with military from other branches for projects . US Navy and US Marine Corps engineers operated side @-@ by @-@ side with 130th Engineer Brigade soldiers , and though commanders reported a " culture clash " between different branches of service , the soldiers , sailors , and Marines were able to adapt to the situation quickly . |
The brigade 's Headquarters Company managed the engineer battalions but it also undertook its own missions , including humanitarian missions and public affairs assignments . It was supported by the brigade 's Special Troops Battalion which provided a wide range of duties for the Headquarters . The task of detecting and removing IEDs proved particularly difficult for the brigade , as IEDs were a serious issue for coalition forces and the leading cause of casualties at the time . The 54th Engineer Battalion under the 130th was specially tasked with counter @-@ IED operations on the over 300 kilometers of roads that the brigade was responsible for . The 249th Engineer Battalion was charged with maintaining the power grid throughout Iraq . They were required to assess 200 power stations throughout the country and make repairs to each one individually . The 84th Engineer Battalion was tasked with most construction projects in the Forward Operating Bases . These projects involved expansion of many of the larger FOBs as smaller ones were shut down and consolidated . One of the main focuses of the Battalion was the expansion of living quarters at Al Asad Air Base . The 565th Engineer Battalion was responsible for maintaining the supply yards housing building materials for the rest of the Brigade 's battalions , and to ensure that the materials were dispersed and used as efficiently as possible . The brigade 's mechanical and vehicle maintenance duties were provided by civilian contractors . These contractors also handled transportation of construction vehicles and vehicle parts to the theater . |
During the year of its deployment in Iraq , the brigade reported progress in numerous areas . Brigade commander Colonel Thomas Kula reported that " greater than 50 percent " of IEDs found on roads used by the Corps were recognized and disarmed before they could be used against coalition forces . The brigade also cleared 700 kilometers of road from trash and debris and filled more than 600 potholes caused by explosions . It also completed 1 @,@ 800 mapping projects in the theater . The brigade also finished numerous building projects around Iraq . Soldiers of the 130th Engineer Brigade completed 345 construction projects during the year in the country , including emplacing four bridges and maintaining eight more , well digging projects throughout western Iraq , maintaining the power grid to 25 coalition bases , repairing and expanding services at FOBs throughout the region , and construction of outposts and checkpoints throughout the country 's roadways with the assistance of Iraqi engineers . During the deployment , a total of 15 soldiers from the brigade were killed in action . The 130th Engineer Brigade returned to Hanau from its second tour in Iraq in October 2006 . |
= = = Reactivation in Hawaii = = = |
With the US Army forces in Europe seeing drawdowns and redeployments , it was announced that V Corps would be eliminated , and the 130th Engineer Brigade would be moved elsewhere . The brigade formally left Hanau with a casing of the unit colors ceremony at Pioneer Kaserne on 4 May 2007 . Casing the unit 's colors was a tradition formally signifying its inactivation and , for all official purposes , the brigade had ceased to be an active Army unit . The brigade headquarters became part of U.S. Army Pacific on 16 June 2007 . |
The brigade had originally been slated to relocate to Fort Lewis , Washington to replace the 555th Engineer Brigade , which was scheduled to be inactivated . But with the announcement of the Grow the Army plan in early 2007 , it was decided that no engineer brigades would be inactivated permanently , and the 130th Engineer Brigade would be moved to Hawaii instead . Both the 130th and 555th Engineer Brigades remained on active duty . |
The brigade was inactive for a year while it was reconstructed in Hawaii . As a part of the transformation of the US Army , the brigade was reorganized into a modular force with new and updated equipment and new personnel . The Brigade stood up provisionally on 27 June 2008 as it neared ready status . On 23 October , the brigade 's colors were formally uncased at Schofield Barracks , Hawaii . This signified the end of the brigade 's relocation to Hawaii as well as its completion and readiness to take on new missions . |
The brigade took command of the 6th , 65th and 84th Engineer battalions . |
= = = Third tour in Iraq = = = |
The brigade was alerted for another deployment to Operation Iraqi Freedom in summer 2009 . There , its missions will once again include construction , route clearance , and training of Iraqi engineers . Since being alerted for deployment , the brigade began conducting vigorous Mission Rehearsal Exercise ( MRE ) training at Schofield Barracks . Among this training has been updated strategies for detection and clearance of Improvised Explosive Devices . The brigade began its deployment on 17 July 2009 , uncasing its colors in Mosul and taking command of construction projects in the area from the 18th Engineer Brigade . |
The 130th Engineer Brigade returned to Schofield Barracks Hawaii from Iraq on 4 June 2010 . |
= = = Theater Security Cooperation Program Exercises = = = |
Upon the 130th Engineer Brigade 's return from Iraq in 2010 , the 130th Engineer Brigade served as the Theater Engineer Brigade in the PACOM AOR . In this capacity , the brigade provided combat engineering , construction engineering and dive operations support to joint and combined partners at more than 30 Theater Security Cooperation Program ( TSCP ) exercises and multiple company sized deployments to Operations New Dawn and Enduring Freedom . |
The 130th Engineer Brigade served as the Combined Joint Civil Military Operations Task Force ( CJMOTF ) for Balikatan 2011 in the Philippines . For over two months , the brigade headquarters along with platoons from the 84th Engineer Battalion built schools and all @-@ purpose facilities . Meanwhile , the brigade 's subordinate joint partners conducted veterinarian and medical events to help improve the lives of the Filipino people . This event sharpened the brigade 's skills at responding to humanitarian aid and disaster response ( HADR ) events throughout the region . Upon completion of BK11 , the brigade shifted its training focus from stability operations to major combat operations . Specifically , the brigade initiated a 9 @-@ month train @-@ up plan for its MCTP graded war @-@ fighter with the 2nd Infantry Division in Korea . Through a series of individual and collective training events the brigade honed , sharpened and in some cases re @-@ learned the skills necessary to achieve victory in a high @-@ intensity conflict . Through UFG12 , 2ID 's War @-@ Path II Exercise , and finally the Full Spectrum Exercise in November 2011 , the 130th Engineer Brigade earned some of the highest marks and accolades ever given to a brigade by the MCTP during a certification war @-@ fighter exercise . Through these series of exercises , the 130th Engineer Brigade helped USFK , 8th Army , and 2ID refine and improve their most significant OPLANs by updating TPFDDs , task organizations , engineer concepts of operations , and combined arms gap @-@ crossing plans . The 130th Engineer Brigade , along with 8th Army and 2ID remain ready to " Fight Tonight " if called upon . |
= = = Operation Enduring Freedom = = = |
The 130th Engineer Brigade Headquarters and Headquarters Company ( HHC ) , and one of their subordinate battalions , the 65th Engineer Battalion ( Combat Effects ) , deployed in support of Operation Enduring Freedom in September and October 2013 . This marked the brigade headquarters ' first deployment to Afghanistan . After a two @-@ week handover period , the 130th Engineer Brigade officially took over on 2 October 2013 from the 555th Engineer Brigade ( from Joint Base Lewis @-@ McChord , WA ) , Joint Task Force Triple Nickel , thus becoming Joint Task Force Sapper , overseeing U.S. Army , Navy , and Air Force engineer units across Afghanistan . A direct subordinate element of ISAF Joint Command and U.S. Forces @-@ Afghanistan , JTF Sapper constituted the fourth largest command in theater , behind only regional commands . The 130th Engineer Brigade became the core of a provisional multi @-@ role brigade headquarters for engineer operations in Afghanistan with seven subordinate battalions , one Naval Mobile Construction Battalion , and one Engineer Prime Beef Squadron consisting of over 4 @,@ 200 Soldiers , Sailors and Airmen operating in each Regional Command . |
From September to December 2013 , Joint Task Force Sapper 's mission in theater was " The Theater Engineer Brigade trains , certifies and advises the ANA Engineers on construction , facility management , and assured mobility capabilities while supporting the retrograde of Coalition Forces through expeditionary construction and assured mobility across the CJOA @-@ A. " |
From January to May 2014 , Joint Task Force Sapper 's mission in theater was " Joint Task Force Sapper partners with ANA engineers to enable their independent operations and support the redeployment and retrograde of Coalition Forces through expeditionary construction and deconstruction across the CJOA @-@ A in order to set the conditions for the resolute support mission . " |
The 130th Engineer Brigade turned over responsibility as Operation Enduring Freedom 's Theater Engineer Brigade to the 2nd Engineer Brigade ( from Joint Base Elmedorf @-@ Richardson , AK ) , Joint Task Force Trailblazer , on 29 May 2014 . The 130th Engineer Brigade returned to Schofield Barracks , Hawaii from Afghanistan on 4 June 2014 . |

= Corythosaurus = |
Corythosaurus / ˌkɒrᵻθoʊˈsɔːrəs / is a genus of hadrosaurid " duck @-@ billed " dinosaur from the Upper Cretaceous Period , about 77 – 75 @.@ 7 million years ago . It lived in what is now North America . Its name means " helmet lizard " , derived from Greek κόρυς . It was named and described in 1914 by Barnum Brown . Corythosaurus is now thought to be a lambeosaurine , related to Nipponosaurus , Velafrons , Hypacrosaurus , and Olorotitan . Corythosaurus has an estimated length of 9 metres ( 30 ft ) , and has a skull , including the crest , that is 70 @.@ 8 centimetres ( 27 @.@ 9 in ) tall . |
Corythosaurus is known from many complete specimens , including the nearly complete holotype found by Brown in 1911 . The holotype skeleton is only missing the last section of the tail , and part of the forelimbs , but was preserved with impressions of polygonal scales . Corythosaurus is known from many skulls with tall crests . The crests resemble the crests of the cassowary and a Corinthian helmet . The most likely function of the crest is thought to be vocalization . As in a trombone , sound waves would travel through many chambers in the crest , and then get amplified when Corythosaurus exhaled . A Corythosaurus specimen has been preserved with its last meal in its chest cavity . Inside the cavity were remains of conifer needles , seeds , twigs , and fruits : Corythosaurus probably fed on all of these . |
The two species of Corythosaurus are both present in slightly different levels of the Dinosaur Park Formation . Both still co @-@ existed with theropods and other ornithischians , like Daspletosaurus , Brachylophosaurus , Parasaurolophus , Scolosaurus , and Chasmosaurus . |
= = Discovery and species = = |
The first specimen , AMNH 5240 , was discovered in 1911 by Barnum Brown in Red Deer River , Alberta , Canada , and secured by him in the Fall of 1912 . As well as an almost complete skeleton , the find was notable because impressions of much of the creature 's skin had also survived . The specimen came from the Belly River Group of the province . The left or underside of the skeleton was preserved in carbonaceous clay , making it difficult to expose the skin . The skeleton was articulated , and only missing about the last 0 @.@ 61 metres ( 2 @.@ 0 ft ) of the tail and the forelimbs . Both scapulae and coracoids are preserved in position , but the rest of the forelimbs are gone , except for phalanges and pieces of humeri , ulnae and radii . Apparently the remaining forelimbs were weathered or eroded away . Impressions of the integument were preserved covering over a large part of the skeletons outlining , and shows the form of the body . Another specimen , AMNH 5338 , was found in 1914 by Brown and Peter Kaisen . Both specimens are now housed in the American Museum of Natural History in their original death poses . |
The type species Corythosaurus casuarius was named by Barnum Brown in 1914 , based on the first specimen collected by him in 1912 . AMNH 5240 is thus the holotype . In 1916 , the original author , Brown , published a more detailed description which was also based on AMNH 5338 , which specimen is therefore the plesiotype . Corythosaurus is among many lambeosaurines that possess crests , and it was the crest that lends Corythosaurus its name . The generic name Corythosaurus is derived from Greek κόρυθος , korythos , " Corinthian helmet " , and means " helmeted lizard " . The specific name casuarius refers to the cassowary , a bird with a similar skull crest . The full binomial of Corythosaurus casuarius thus means " Cassowary @-@ like reptile , with a Corinthian helmet crest " . |
The two best preserved specimens of Corythosaurus found , by Charles H. Sternberg in 1912 , were lost on 6 December 1916 while being carried to the United Kingdom , during World War One . They were being sent to Arthur Smith Woodward , a paleontologist of the British Museum of Natural History in England , when the ship transporting them was sunk by the German merchant raider SMS Möwe in the middle of the ocean . |
There were formerly up to seven species described , including C. casuarius , C. bicristatus Parks 1935 , C. brevicristatus Parks 1935 , C. excavatus Gilmore 1923 , C. frontalis Parks 1935 , and C. intermedius Parks 1923 . In 1975 Peter Dodson studied the differences between the skulls and crests of different species of lambeosaurine dinosaurs . He found that the differences in size and shape may have actually been related to the gender and age of the animal . Now only one species is recognized for certain , C. casuarius , although C. intermedius has been recognized as valid in some studies . It is based on specimen ROM 776 , a skull found by Levi Sternberg in 1920 and was named by William Parks in 1923 , who had originally named it Stephanosaurus intermedius earlier that year . The specific name of C. intermedius is derived from its apparent intermediate position according to Parks . C. intermedius lived at a slightly later time in the Campanian than C. casuarius , and the two species are not identical , which supported the separation of them in a 2009 study . |

Benson et al . ( 2012 ) estimated that Corythosaurus has an average length of 9 metres ( 30 ft ) . Richard Swann Lull 's earlier length estimate , published in 1942 , found a slightly longer total length of 9 @.@ 4 m ( 31 ft ) , a size similar to Lambeosaurus lambei , another Canadian lambeosaurine . In 1962 , Edwin H. Colbert used models of specific dinosaurs , including Corythosaurus , to estimate their weight . The Corythosaurus model used , was modelled by Vincent Fusco after a mounted skeleton , and supervised by Barnum Brown . After testing , it was concluded that the average weight of Corythosaurus was 3 @.@ 82 tonnes ( 3 @.@ 76 long tons ; 4 @.@ 21 short tons ) . More recent size estimates of Corythosaurus , published in 2001 , find the genus to be among the largest hadrosaurids , only smaller than Shantungosaurus and Parasaurolophus . The total length of Corythosaurus specimen AMNH 5240 was found to be 8 @.@ 1 m ( 27 ft ) , with a weight of 3 @.@ 0785 tonnes ( 3 @.@ 0299 long tons ; 3 @.@ 3935 short tons ) . |
Proportionally , the skull is much shorter and smaller than that of Edmontosaurus ( formerly Trachodon ) , Kritosaurus , or Saurolophus , but when including its crest , its superficial area is almost as large . |
= = = Skull = = = |
Over twenty skulls have been found from this dinosaur . As with other lambeosaurines , the animal bore a tall , elaborate bony crest atop its skull , which contained the elongate narial passages . The narial passages extended into the crest , first into separate pockets in the sides , then into a single central chamber and onward into the respiratory system . The skull of the type specimen has no dermal impressions on it . During preservation it was compressed laterally , so now the width is about two @-@ thirds what it would have been in real life . According to Brown , the compression also caused the nasals to shift where they pressed down on the premaxillaries . Because they were pressed on the premaxillaries , the nasals would have closed the nares . Apart from the compression , the skull appears to be normal . Contrary to what Brown assumed , the areas concerned were fully part of the praemaxillae . |
The crests of Corythosaurus resemble that of a cassowary , or a Corinthian helmet . They are formed by a combination of the praemaxillae , nasals , prefrontals and frontals , as in Saurolophus , but instead of projecting backwards as a spine , they rise up to make the highest point above the orbit . The two halves of the crest are separated by a median suture . In front of the orbit , the crest is made of thick bone . |
The nasals make up most of the crest . Brown assumed that they extended from the beaks ' tip to the highest spot along the crest and that , unlike those in other genera , the nasals meet in the centre and are not separated in front by an ascending premaxillary process . Brown however , mistook the praemaxillae for the nasals ; the snout is actually largely formed by them and they do separate the nasals . Brown also thought that on the top and back of the crest , the whole external face is covered by the frontals . Again he made a mistake : what he assumed to be the frontals are in fact the nasals . The nasals end at the back of the squamosals in a hooked , short process . The prefrontals also make up part of the crest ; however , Brown mistook the lower upper branch of the praemaxilla for the prefrontal . The actual prefrontal , triangular in shape , is located at the side of the crest base ; it was by Brown seen as a part of the frontal . The real frontals , largely internal to the crest base structure , are not visible from the side . |
The mouth of the holotype of Corythosaurus is narrow . The praemaxillae each form two long folds . The folds enclose air passages extending the narial passages to the front of the snout . There they end in narrow openings , sometimes called " pseudonares " , false bony nostrils . These were mistaken by Brown for the real nares or nostrils . These are actually situated inside the crest , above the eye sockets . As in Saurolophus , the expanded portion of the premaxillary in front of the pseudonaris ' opening is elongate : by comparison , in Kritosaurus , the bill is short , and the pseudonares extend far forward . At the end of the Corythosaurus bill , the two pseudonares unite into one . Because of his incorrect identification , Brown assumed that the holotype 's inferior process of the premaxillary was shorter than in Kritosaurus and Saurolophus , and that the process does not unite with the lacrimal , another difference from those genera . The praemaxilla actually does touch the lacrimal and extends to the rear until well behind the eye socket . |
The lower jaw of the holotype is 66 @.@ 9 centimetres ( 26 @.@ 3 in ) long , and 10 centimetres ( 3 @.@ 9 in ) deep . The total length of the crest from the beak to the uppermost tip of the type specimen is 83 @.@ 7 centimetres ( 33 @.@ 0 in ) , its total length is 81 @.@ 2 centimetres ( 32 @.@ 0 in ) , and height 70 @.@ 8 centimetres ( 27 @.@ 9 in ) . |
= = = Soft tissue = = = |
In the holotype of C. casuarius , the sides and tail of the body are covered in scales of several types . Polygonal tuberculate scales , covered in small bumps , vary in size over the body . Conical limpet @-@ like scales are only preserved on a fold of skin preserved on the back of the tibia , but which was probably from the bottom of the belly , rather than the leg . Separating the polygonal scales of C. casuarius are shieldlike scales , arranged close together in rows . Ossified tendons are present on all the vertebrae , except for those in the cervical region . On no vertebrae do the tendons extend below the transverse processes . Each tendon is flattened at its origin , and transversely ovoid in the central rod , ending at a rounded point . |
Aside from those found on Corythosaurus casuarius , extensive skin impressions have been found on Edmontosaurus annectens and notable integument has also been found on Brachylophosaurus canadensis , Gryposaurus notabilis , Parasaurolophus walkeri , Lambeosaurus magnicristatus , L. lambei , Saurolophus angustirsotris and on unidentified ornithopods . Of these , L. lambei , C. casuarius , G. notabilis , P. walkeri , and S. angustirsotris have preserved polygonal scales . The scales on L. lambei , S. angustirostris and C. casuarius are all similar . Corythosaurus is one of very few hadrosaurids which have preserved skin impressions on the hind limbs and feet . A study in 2013 showed that amongst hadrosaurids , Saurolophus angustirostris preserved the best and most complete foot and limb integument , although other species like S. osborni , Edmontosaurus annectens and Lambeosaurus lambei ( = L. clavinitialis ) share a fair amount of preserved tissue on those regions . |
It was once thought that this dinosaur lived mostly in the water , due to the appearance of webbed hands and feet . However , it was later discovered that the so @-@ called " webs " were in fact deflated padding , much like that found on many modern mammals . |
= = = Distinguishing characteristics = = = |
A set of characters were indicated by Barnum Brown in 1914 to distinguish Corythosaurus from all other hadrosaurids from Alberta : a comparatively short skull with a high helmet @-@ like crest formed by the nasals , prefrontals and frontals ; the nasals not being separated in front by the premaxillaries ; a narrow beak , with an expansion in front of an elongated naris ; and a small narial opening . |
In 1916 , Brown expanded the character set to include more features ; in the revised version : a comparatively short skull with a high helmet @-@ like crest formed by nasals , prefrontals and frontals ; the nasals not being separated in front by premaxillaries ; a narrow beak , expanded section in front of the elongated nares ; a small narial opening ; a vertebral formula of 15 cervicals , 19 dorsals , 8 sacrals , and 61 + caudals ; possession of dorsal spines of a medium height ; high anterior caudal spines ; long chevrons ; long scapulae , possessing a blade of medium width ; a radius considerably longer than humerus ; comparatively short metacarpals ; an anteriorly decurved ilium ; a long ischium with a foot @-@ like terminal expansion ; a pubis with an anterior blade that is short and broadly expanded at end ; a femur that is longer than the tibia ; the phalanges of pes are short ; that the integument over the sides and tail composed of polygonal tuberculate scales without pattern but graded in size in different parts of the body ; and a belly with longitudinal rows of large conical limpet @-@ like scales separated by uniformly large polygonal tubercles . Again , the presumed traits of the snout are incorrect because Brown confused the praemaxillae with the nasal bones and the nasal bones with the frontals . Most of the postcranial traits are today known to be shared with other lambeosaurines . |
= = Classification = = |
Originally , Brown referred to Corythosaurus as a member of the family Trachodontidae ( now Hadrosauridae ) . Inside Trachodontidae were the subfamilies Trachodontinae and Saurolophinae . Brown classified Hadrosaurus , Trachodon , Claosaurus , and Kritosaurus in Trachodontinae , and Corythosaurus , Stephanosaurus , and Saurolophus in Saurolophinae . |
Later , Brown revised the phylogeny of Corythosaurus , and found that it was closely related , and possibly ancestral to Hypacrosaurus . The only differences he found between them were the development of the vertebrae , and the proportions of the limbs . During a study of dinosaurian ilia in the 1920s , Alfred Sherwood Romer proposed that the two orders of dinosaurs might have evolved separately , and that birds , based on the shape and proportions of their ilia might truly be specialized ornithischians . He used both Tyrannosaurus and Corythosaurus as a base model to analyze which theory is more likely true . He found that even though birds are thought of as saurischians , it is very plausible for them to have evolved their specific pelvic musculature and anatomy if they evolved from ornithschians like Corythosaurus . However , even though Corythosaurus does resemble modern birds in pelvic structure more than saurischians , birds are now thought to have descended from the latter . |
Corythosaurus is currently classified as a hadrosaurid , in the subfamily Lambeosaurinae . It is related to other hadrosaurs such as Hypacrosaurus , Lambeosaurus and Olorotitan , with the exception of Olorotitan they all share similar looking skulls and crests . However , research published in 2003 has suggested that even though it possesses a unique crest , Olorotitan is Corythosaurus closest known relative . Benson et al . ( 2012 ) found that Corythosaurus was closely related to Velafrons , Nipponosaurus , and Hypacrosaurus , and said that they formed a group of fan @-@ crested lambeosaurines . |
In 2014 , a study including the description of Zhanghenglong was published in the journal PLOS ONE . The study included an almost complete cladogram of hadrosauroid relationships , including Corythosaurus as the most derived lambeosaurine , as sister taxon to Hypacrosaurus . The below cladogram is a simplified version including only Lambeosaurini . |
= = Paleobiology = = |
Comparisons between the scleral rings of Corythosaurus and modern birds and reptiles suggest that it may have been cathemeral , active throughout the day at short intervals . The sense of hearing in hadrosaurids , specifically such as Lophorhothon , also seems to have been greatly developed because of an elongated lagena . The presence of a thin stapes ( an ear bone that is rod @-@ like in reptiles ) , combined with a large eardrum implies the existence of a sensitive middle ear . It is possible that hadrosaurid ears are sensitive enough to detect as much sound as a modern crocodilian . |
= = = Crest function = = = |
The internal structures of the crest of Corythosaurus are quite complex , making possible a call that could be used for warning or attracting a mate . Nasal passageways of Corythosaurus , as well as Hypacrosaurus and Lambeosaurus are S @-@ shaped , with Parasaurolophus only possessing U @-@ shaped tubes . Any vocalization would travel through these elaborate chambers , and probably get amplified . Scientists speculate that Corythosaurus could make loud , low pitched cries " like a wind or brass instrument " , such as a trombone . The sounds could serve to alert other Corythosaurus to the presence of food or a potential threat from a predator . The nasal passages emit low @-@ frequency sounds when Corythosaurus exhaled . The individual crests would produce different sounds , so it is likely that each species of lambeosaurine would have had a unique sound . However , even though the range for different lambeosaurine nasal passages vary , they all probable made low @-@ pitched sounds . This might be because low sounds ( below 400 Hz ) travel a set distance in any environment , while higher ( above 400 Hz ) sounds have a larger spread in the distance travelled . |
When they were first described , crested hadrosaurs were thought to be aquatic , an assessment based incorrectly on webbing that is now known to be padding . The theory was that the animals could swim deep in the water , and use the crest to store air to breath . However , it has now been proven that the crest did not have any holes in the end , and the water pressure at even 3 metres ( 9 @.@ 8 ft ) would be too great for the lungs to be able to inflate . |

Corythosaurus casuarius is one of a few lambeosaurines , along with Lambeosaurus lambei , Hypacrosaurus stebingeri and H. altispinus , to have had surviving fossilized juveniles assigned to it . Juveniles are harder to assign to species , because at a young age they lack the distinctive larger crests of adults . As they age , lambeosaurine crests tend to grow and become more prominent come maturity . In the Dinosaur Park Formation , over fifty articulated specimens have been found , coming from many different genera . Among them , juveniles are hard to identify at the species level . Earlier , four genera and thirteen species were recognized from the formation 's area , when paleontologists used differences in size and crest shape to differentiate taxa . The smallest specimens were identified as Tetragonosaurus , now seen as a synonym of Procheneosaurus , and the largest skeletons were called either Corythosaurus or Lambeosaurus ; an adult was identified as Parasaurolophus . Small lambeosaurines from the Horseshoe Canyon Formation were referred to Cheneosaurus . |
Corythosaurus started developing its crest when half the size of adults , but Parasaurolophus juveniles grew crests when only 25 % as long as adults . Juvenile Corythosaurus , along with adults , had a premaxilla @-@ nasal fontanelle . Young and adult Corythosaurus are similar to Lambeosaurus and Hypacrosaurus but dissimilar to Parasaurolophus in that the sutures of the skull are sinuous , and not smooth and straight . This feature helps differentiate parasaurolophins from lambeosaurins . Generally , the crests of juveniles of lambeosaurines like Corythosaurus , Lambeosaurus , Hypacrosaurus stebingeri , parasaurolophines like Parasaurolophus , and primitive lambeosaurines like Kazaklambia are quite alike , although other features can be used to distinguish them . |
Work by Dodson ( 1975 ) recognized that there were many less taxa present in Alberta . Tetragonosaurus was found to be juveniles of Corythosaurus or Lambeosaurus . T. erectofrons was assigned to Corythosaurus based largely on biometric information . The only non @-@ typic specimen of Tetragonosaurus , assigned to T. erectofrons , was found later to be referable to Hypacrosaurus , although the holotype of the species was still found to be assignable to Corythosaurus . |

Corythosaurus was an ornithopod , and therefore a herbivore . Benson et al . ( 2012 ) realized that the beak of Corythosaurus was shallow and delicate , and concluded that it must have been used to feed upon soft vegetation . Based on the climate of the Late Cretaceous , they guessed that Corythosaurus would have been a selective feeder , eating only the juiciest fruits and youngest leaves . Corythosaurus specimens have been preserved with its last meal in its chest cavity . Inside the cavity were remains of conifer needles , seeds , twigs , and fruits , meaning that Corythosaurus probably fed on all of these . |

Fossils have been found in the upper Oldman Formation and lower Dinosaur Park Formation of Canada . The Oldman Formation dates to the Campanian , about 77 @.@ 5 to 76 @.@ 5 million years ago , and the Dinosaur Park Formation dates from 76 @.@ 6 to 74 @.@ 8 million years ago . Corythosaurus lived from ~ 77 – 75 @.@ 7 million years ago . In the Dinosaur Park Formation C. casuarius lived from 76 @.@ 6 to 75 @.@ 9 mya , with C. intermedius living from 75 @.@ 8 to 75 @.@ 7 mya . In the Oldman Formation C. casuarius , the only species of Corythosaurus from the deposits , lived about 77 to 76 @.@ 5 mya . The holotype specimen was clearly a carcass that had floated up on a beach , as Unio shells , water @-@ worn bones , and a baenid turtle were preserved all around . Corythosaurus probably lived in a woodland forest , and might have occasionally wandered into swampy areas . |
A limited fauna is known from the upper section of the Oldman Formation , and Corythosaurus casuarius as well as C. intermedius are among the taxa . Also from the section of the formation are the theropods Daspletosaurus , and Saurornitholestes , the hadrosaurids Brachylophosaurus , Gryposaurus and Parasaurolophus , and the ankylosaurid Scolosaurus , and the ceratopsians Coronosaurus and Chasmosaurus . Other genera are known , but do not persist from the upper section of the formation , and therefore are not contemporaries of Corythosaurus . |
Corythosaurus casuarius is widespread throughout the lower unit of the Dinosaur Park Formation . In it , Corythosaurus was found to be closely associated with the ceratopsid Centrosaurus apertus . Their associating was found in the Dinosaur Park , Judith River , and Mesaverde formations , and also in the Wind River Basin and the Wheatland County area . Corythosaurus lived alongside numerous other giant herbivores , such as the hadrosaurids Gryposaurus and Parasaurolophus , the ceratopsids Centrosaurus and Chasmosaurus , and ankylosaurids Scolosaurus , Edmontonia and Dyoplosaurus in the earliest stages of the formation , Dyoplosaurus , Panoplosaurus and Euoplocephalus in the middle age , and Euoplocephalus alone in later stages of the formation . Studies of the jaw anatomy and mechanics of these dinosaurs suggests they probably all occupied slightly different ecological niches in order to avoid direct competition for food in such a crowded eco @-@ space . The only large predators known from the same levels of the formation as Corythosaurus are the tyrannosaurids Gorgosaurus libratus and an unnamed species of Daspletosaurus . |
Thomas M. Lehman has observed that Corythosaurus hasn 't been discovered outside of southern Alberta even though it is one of the most abundant Judithian dinosaurs in the region . Large herbivores like the hadrosaurs living in North America during the Late Cretaceous had " remarkably small geographic ranges " despite their large body size and high mobility . This restricted distribution strongly contrasts with modern mammalian faunas whose large herbivores ' ranges " typical [ ly ] ... span much of a continent . " |

Ghost in the Shell : Stand Alone Complex - Solid State Society ( Japanese : 攻殻機動隊 STAND ALONE COMPLEX Solid State Society , Hepburn : Kōkaku Kidōtai STAND ALONE COMPLEX Solid State Society ) is a 2006 made @-@ for @-@ television science fiction action spy thriller anime film and is part of the Ghost in the Shell : Stand Alone Complex series based on Masamune Shirow 's manga Ghost in the Shell . It was produced by Production I.G and directed by Kenji Kamiyama . |
The film is set in 2034 , two years after the events of 2nd GIG . Togusa is now the team leader for Public Security Section 9 , which has increased considerably in size . Section 9 deals with a series of complicated incidents , including the assassination of Ka Rum , a former dictator of the Siak Republic , which leads to a terrorist plot using children as vectors for a cybernetic virus . Investigations reveal that a hacker nicknamed the " The Puppeteer " is behind the entire series of events . |
The film , which had a production budget of 360 million yen , debuted in Japan on SKY PerfecTV ! on September 1 , 2006 and it was released in North America in 2007 . A stereoscopic 3D version of the film was released in 2011 . The film received generally positive reviews , but was criticized for being very dialogue heavy and lacking in action . |
= = Plot = = |
In 2034 , two years after the events of 2nd GIG , Public Security Section 9 is investigating a string of mysterious suicides by refugees from the Siak Republic . Chief Aramaki conducts a raid to arrest the refugee dictator only to find him already dead . In retaliation , a Siak operative plans a terrorist attack with a micromachine virus . Batou is sent to intercept the Siak operative and encounters Kusanagi , who is conducting her own investigation . Before they can apprehend the operative , he dies while attacking them . Kusanagi takes a case of virus ampules and warns Batou to stay away from the Solid State Society before leaving . |
Section 9 operatives develop a theory that a hacker known as the Puppeteer is responsible for Siak agents ' forced suicides and Togusa discovers sixteen kidnapped children who were intended carriers of the virus . All the children are listed as the children of Noble Rot Senior Citizens and Section 9 begins to suspect a larger conspiracy when they are part of a larger body of 20 @,@ 000 children . Soon afterwards , the Puppeteer causes the disappearance of the sixteen children and Batou reveals to Togusa that he believes Kusanagi to be the Puppeteer . Section 9 next intercepts a Siak sniper that is targeting the supposed mastermind of Ka Rum 's assassination . After his capture it is revealed the informant and the target are one in the same . The sniper says that the Puppeteer is a mechanism in the Solid State and cannot be killed . |
Togusa tracks down one of the missing children , now assigned to an elderly man in the Noble Rot program . As Togusa tries to take the child , the man awakens and demands the child be left with him as he had named the child as his sole heir . He would rather give his assets to a child off the street and to protect them from abuse than have his assets turned over to the government upon his death . The man immediately dies after warning Togusa not to interfere with the will of the Solid State . Late , Togusa receives a call from the Puppeteer who hacks his brain and forces him to drive to a cyberbrain implant hospital with his daughter . The Puppeteer and Togusa converse , and Togusa is given the option to lose his daughter to the Solid State or commit suicide . He chooses suicide but is saved by Kusanagi who then identifies the Puppeteer as a rhizome formed by the collective consciousness of the Noble Rot Senior Citizens located in a welfare center . |
Kusanagi temporarily rejoins Section 9 and confirms that Ito Munei , an influential politician , was behind the assassination of General Ka Rum . She also confirms that Munei and other politicians use it as a front for a brainwashing facility to create an elite group of pure @-@ blooded Japanese to take control of the country in the next generation and lead it into Munei 's vision of a new Golden Age . The Solid State decided to eliminate Munei for interfering in its plans , but Munei was ignorant of the origin of the abduction infrastructure . |
A designer named Tateaki Koshiki steps forward , claiming he developed the Solid State system before committing suicide . Kusanagi dives into his cyberbrain and into Koshiki 's trap , allowing him to hack her cyberbrain . The Puppetmaster reveals that he was spread across several egos until a collective consciousness emerged and developed into a Solid State , allowing him to move into the society beyond as the vanishing mediator . Later , Batou tells a recovering Kusanagi that the real Tateaki Koshiki used a cybernetic body and built the Solid State after he was hired by Munei . Kusanagi does not reveal that the Puppeteer was a fragment of herself , but Batou already knew from being linked to her during the dive . Batou concludes that the ultimate identity of the Puppeteer will remain unknown and that incident will be written off a scandal . |
