Select locations now offer curbside pickup & … [22], Unlike those of many other long-necked animals, the individual neck vertebrae were not particularly elongated; rather, the extreme neck length was achieved by a much increased number of vertebrae. The neck anatomy of elasmosaurids was capable of making a gentle slope to allow them to breathe at the surface but would have required them to engage in energy-expensive swimming at the sub-surface. The mandibular symphysis (where the two halves of the lower jaw connected) was well ossified, with no visible suture. Marsh returned to the issue during their controversy in the New York Herald in the 1890s (Marsh claimed he had pointed out the error to Cope immediately), when their dispute gained widespread public attention. Elasmosaurus is a genus of plesiosaur with an extremely long neck that lived in the Late Cretaceous period, 80.5 million years ago. Thought to be the lochness monster. We can’t wait to continue making a huggable world together! Discover (and save!) Only one incomplete Elasmosaurus skeleton is definitely known, consisting of a fragmentary skull, the spine, and the pectoral and pelvic girdles, and a single species is recognized today; other species are now considered invalid or have been moved to other genera. They were herbivorous and possessed strong cheek teeth to help them chew tough, fibrous plants. Each plush comes with a Certificate of Authenticity tag. [16] While he initially assigned it in 1890 to a new species of Cimoliasaurus, C. snowii,[44] he subsequently recognized the elasmosaurid nature of its humerus and coracoids. By the 63rd vertebra, the articular facet was also quadratic in shape with rounded edges, whereas the centra of the hindmost vertebrae had a broad oval outline. The type remains were discovered by him in the same 1874 expedition with Mudge. Suitable for ages 3 plus including educational information in five languages. Contrary to earlier depictions, their necks were not very flexible, and could not be held high above the water surface. Figurice strip junaka, likova iz serija i filmova Hulk, Hobit - pogledaj ponudu prodavnica i uporedi cene figurica. While they were incomplete, Persson recognized that their proportions and the shape of their articular ends differed greatly from pliosauroids, and instead agreed well with elasmosaurids. Elasmosaurus (/ɪˌlæzməˈsɔːrəs, -moʊ-/;[1]) is a genus of plesiosaur that lived in North America during the Campanian stage of the Late Cretaceous period, about 80.5 million years ago. [47] As of 2013, this questionable attribution remains unchanged. [2] Since the last tail-vertebrae of elasmosaurids were fused into a structure similar to the pygostyle of birds, it is possible this supported a tail-fin, but the shape it would have had is unknown. [34] In 1962 Welles further subdivided elasmosaurids based on whether they possessed pelvic bars formed from the fusion of the ischia, with Elasmosaurus and Brancasaurus being united in the subfamily Elasmosaurinae by their sharing of completely closed pelvic bars.

[8], The flexion ranges of Elasmosaurus necks would have allowed the animal to employ a number of hunting methods including "benthic grazing", which would have involved swimming close to the bottom and using the head and neck to dig for prey on the sea floor. [74][75][38] Their analysis also moved Muraenosaurus to the Cryptoclididae, and Microcleidus and Occitanosaurus to the Plesiosauridae;[73] Benson and Druckenmiller isolated the latter two in the group Microcleididae in 2014, and considered Occitanosaurus a species of Microcleidus.

Son of Kong (also known as The Son of Kong) is a 1933 American Pre-Code adventure monster film produced by RKO Pictures.Directed by Ernest Schoedsack and featuring special effects by Willis O'Brien and Buzz Gibson, the film stars Robert Armstrong, Helen Mack and Frank Reicher.The film is the sequel to (and was released nine months after) King Kong [8], In subsequent years, Elasmosauridae came to be one of three groups in which plesiosaurs were classified, the others being the Pliosauridae and Plesiosauridae (sometimes merged into one group). In early 1867, the American army surgeon Theophilus Hunt Turner and the army scout William Comstock explored the rocks around Fort Wallace, Kansas, where they were stationed during the construction of the Union Pacific Railroad. Fiesta’s story began in California on the Santa Monica Pier, and has since evolved to become a premier plush toy company. Not for children under 3 yrs.. The fish remains were identified as Enchodus and other clupeomorph fish. The head and shoulders of the Elasmosaurus probably acted as a rudder. Until now, you had to spend all day building a time machine just to hang out with a brachiosaurus but now all you have to do is grab this large brachiosaurus stuffed animal and get down to business. marshii to a genus of its own, Thalassonomosaurus;[37] however, Carpenter sunk T. marshii into Styxosaurus snowii in 1999. From Aardvarks to Zebras and everything in between, everyday we strive to … [49] However, the validity of all these species has been questioned. [92], Elasmosaurid remains provide some evidence they were preyed upon. Sea Monsters. More than half of its length was neck, which had more than 70 vertebrae, more than any other animal. The only way it could have done something like that was if it was in a shallow lake, otherwise, it would’ve been impossible for it to lift anything other than its small head above the waves. Plesiosaur anatomy was sufficiently well known at the time that Cope should not have made the mistake, according to Davidson. It became broader towards the front, where it was almost the same breadth as the centrum of the atlas. [22], Following the description of the type species, E. platyurus, a number of other Elasmosaurus species were described by Cope, Williston, and other authors. Cope had apparently concluded that the tail vertebrae belonged to the neck, since the jaws had been found at that end of the skeleton, even though the opposite end terminated in the axis and atlas bones that are found in the neck. At its deepest, it may have been only 800 or 900 meters (2,600 or 3,000 ft) deep. [72] However, Ketchum and Benson's analysis instead included it in the Leptocleidia,[73] and its inclusion in that group has remained consistent in subsequent analyses. [34] In 1995 Nathalie Bardet and Pascal Godefroit also recognized it as an elasmosaurid, albeit indeterminate. 4.9 out of 5 stars with 84 reviews. we put the extraordinary into everything we do, trailblazing the way for innovative and award-winning toys. Nicholas Buesen. Blogger. Travel to ancient oceans with Elmer, or ride the rails in his fanciful train car. In June, Turner gave three fossil vertebrae to the American scientist John LeConte, a member of the railway survey, to take back east to be identified. The usual number of trail vertebrae in elasmosaurids is 30. Approximately 23 kilometers (14 mi) northeast of Fort Wallace, near McAllaster, Turner discovered the bones of a large fossil reptile in a ravine in the Pierre Shale formation, and though he had no paleontological experience, he recognized the remains as belonging to an "extinct monster". The pre-and post-zygapophyses of the neck vertebrae, processes that articulated adjacent vertebrae so they fit together, were of equal length; the former reached entirely over the level of the centrum whereas the latter reached only with their back half. [50], In a 1918 review of the geographic distribution and evolution of Elasmosaurus, Pravoslavlev provisionally assigned three other previously named species to Elasmosaurus;[48] his taxonomic opinions have not been widely followed. These are by Geoworld. [41], Subsequently, a series of 19 neck and back vertebrae from the Big Bend region of the Missouri – part of the Pierre Shale formation – were found by John H. Charles. He divided plesiosaurs into two superfamilies, the Plesiosauroidea and Pliosauroidea, based on neck length, head size, ischium length, and the slenderness of the humerus and femur (the propodialia). Along with its relative Albertonectes, it was one of the longest-necked animals to have lived, with the second largest number of neck vertebrae known, 72, 4 less than Albertonectes. Cope was only in his late twenties and not formally trained in paleontology, and may have been influenced by Leidy's mistake of reversing the vertebral column of Cimoliasaurus. marshii. Jellyray Elasmosaurus is the 2rd skin for Elasmosaurus. Elasmosaurus, like many plesiosaurs, had a small head at the end of a long neck and a mouth full of needle-like teeth. Further back in the front part of the neck, around the 25th vertebra, the lower edge of the articular facets became more concave, and the facet shaped like a quadrate with rounded edges. He considered Elasmosauridae to be closest to the Pliosauridae, noting their relatively narrow coracoids as well as their lack of interclavicles or clavicles. Also, with their long, slender teeth adapted for seizing prey and not tearing, elasmosaurids most certainly swallowed their prey whole. [81][88], Although elasmosaurids are commonly found with several gastroliths, Elamosaurus has only been found uncontroversially with a pebble lodged in the neural arch of one of its hindmost tail-vertebrae.

The neck could have had other vulnerabilities, for example being a target for predators. [2], Today, the incomplete holotype specimen, catalogued as ANSP 10081, is the only definite specimen of Elasmosaurus. Discover (and save!) [16] He again made reference to a new species of Elasmosaurus, from Kansas, in 1908. Free weblog publishing tool from Google, for sharing text, photos and video. Elasmosaurus ("plate lizard") is one of the more famous members of the Plesiosaurs, or near lizards, a major group of Mesozoic Era marine reptiles. $26.38. [17], Fossils that may have belonged to the holotype were found by the American geologist Benjamin Franklin Mudge in 1871, but have probably been lost since. He considered this to be partially an artifact of preservation, but could not understand how the compression affected only the central portion and not the articular ends of the centrum. [38] Danielle Serratos, Druckenmiller, and Benson could not resolve the position of Elasmosaurus in 2017, but they noted that Styxosaurinae would be a synonym of Elasmosaurinae if Elasmosaurus did fall within the group. Seventy-five million years ago, there really were sea monsters, and this long-necked Elasmosaurus from was one of them. ", "Computer Simulations Imply Forelimb-Dominated Underwater Flight in Plesiosaurs", "The four-flipper swimming method of plesiosaurs enabled efficient and effective locomotion", "An integrated approach to understanding the role of the long neck in plesiosaurs", "Functional morphology and hydrodynamics of plesiosaur necks: Does size matter? [67][68] Although the placement of Elasmosaurus in the Elasmosauridae remained uncontroversial, opinions on the relationships of the family became variable over subsequent decades.

The skull would have been slender and triangular, with large, fang-like teeth at the front, and smaller teeth towards the back. Cope had loaned these elements to the English sculptor Benjamin Waterhouse Hawkins to help prepare them out of their surrounding concretions. Olorotitan is a genus of hadrosaurid dinosaur that originated from Late Cretaceous Asia. Dolichorhynchops plush by Wild Republic; Elasmosaurus with Pteranodon in mouth, by Bandai ; Elasmosaurus? The argument was part of the "Bone Wars" rivalry between the two, and is well known in the history of paleontology. A ridge ran along the top of these vertebrae, and the lower sides of the centra were rounded, and bore pairs of nutritive foramina, separated by low ridges. Most Elasmosaurus pictures have this animal with its head sticking out of the waves, which paleontologists now know is an impossibility for this animal to have done that. Most terrific Dinosaur who eats leaves & swims in the ocean. Often pictured raising his long neck above the water, scientists still don’t know why his neck was so long! Elasmosaurus had a long neck (around 25 feet) with 71 neck vertebrae that offered a great flexibility to control their head.

R Exclusive, only available at Toys R Us Canada. His diagnosis of the Elasmosauridae also noted the moderate length of the skull (i.e., a mesocephalic skull); the neck ribs having one or two heads; the scapula and coracoid contacting at the midline; the blunted rear outer angle of the coracoid; and the pair of openings (fenestrae) in the scapula–coracoid complex being separated by a narrower bar of bone compared to pliosaurids.

Feb 20, 2013 - Animal Planet Deep Sea Exploration Playset Elasmosaurus with Exploration Raft by Toys R Us. The vertebrae were, according to Cope, the shortest among members of the genus (approaching Cimoliasaurus in this condition), but he still considered them as belonging to Elasmosaurus due to their compressed form. [53] Wilhelm Deecke moved chilensis to Pliosaurus in 1895,[54] a classification which was acknowledged by Pravoslavlev. [15][2], The atlas and axis bone complex, consisting of the first two neck vertebrae and articulated with the back of the skull, was long, low, and horizontally rectangular in side-view. [78] In 2020, O'Gorman formally synonymized Styxosaurinae with Elasmosaurinae based on the inclusion of Elasmosaurus within the group, and also provided a list of diagnostic characteristics for the clade. The largest Pachyrhinosaurus species were 8 meters (26 ft) long, stood about 7-10 feet tall and weighed about as much as 4-5 tons. If more remains showed E. orientalis to have had a long neck like Elasmosaurus, he stated the image may instead represent Cimoliasaurus better.
