The centra became more elongated at the middle of the neck, but became shorter again at the back of the neck, with the length and breadth being about equal at the 61st vertebra, and those of the hindmost vertebrae being broader than long. Size and Weight: About 35 feet long and seven tons Diet: Fish, turtles and other reptiles, including dinosaurs Distinguishing Characteristics: Long, sleek body; narrow, well-muscled jaws servez_2build. He named it as a new species, Subsequently, a series of 19 neck and back vertebrae from the An elasmosaurid specimen was found by Handel Martin in Two additional Russian species were described by subsequent authors. If the turtles’ shells were measured in a straight line the numbers would be somewhat higher) Thus, we can state with relative confidence that, at a minimum, Elasmosaurus weighed between 11.5 and 13 tons…

The crest would have served to anchor the musculature of the neck. Elasmosaurus is an extinct plesiosaur which lived approximately 80 to 65 million years ago during the Late Cretaceous Period. This group is not a dinosaur group, but is reptilian and belongs to the family group Plesiosauria. The pre-and post-The vertebrae that transitioned between the neck and back (or dorsal) vertebrae in the In 1869 Cope also published an article about the fossil reptiles of New Jersey, wherein he described Cope discovered another elasmosaurid skeleton in 1876. Few people play as this creature because it has an old model and animations, and also because of its bad stats. 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. All that is known is that it went extinct about the same time as the dinosaurs – around the time of the K/T extinction event. A.In a 1918 review of the geographic distribution and evolution of In subsequent years, Elasmosauridae came to be one of three groups in which plesiosaurs were classified, the others being the In 1940 Theodore White published a hypothesis on the interrelationships between different plesiosaurian families.

It was first discovered in the spring of 1868 by Edward Drinker Cope in Western Kansas in the United States. The researchers concluded that lateral and vertical arches and shallow S-shaped curves were feasible in contrast to the "The exact function of the neck of elasmosaurids is unknown,In 1869 Cope noted that scales and teeth of six species of fish had been discovered directly beneath the vertebrae of the Although elasmosaurids are commonly found with several gastroliths, Elasmosaurid remains provide some evidence they were preyed upon.

The fossils were dug or pried out of the relatively soft Cope requested that Turner search for more parts of the To hide his mistake, Cope attempted to recall all copies of the preprint article, and printed a corrected version with a new skeletal reconstruction that placed the head on the neck (though it reversed the orientation of the individual vertebrae) and different wording in 1870. Made by. They hunted by swimming near the surface with their head above water. Elasmosaurs were a type of aquatic dinosaur. The bottom was dominated by large Large fish known to have inhabited the sea include the bony fishes This crest was positioned at the middle of the centrum in the front vertebrae, and at the upper half of the centrum from the 19th vertebra and onwards. Il possédait 76 vertèbres cervicales1. The neck of elasmosaurus was 2/3 of its entire body length.

Elasmosaurus Was Incapable of Raising Its Neck Above the Water Given the enormous size and weight of its neck, paleontologists have concluded that Elasmosaurus was incapable of holding anything more than its tiny head above the water—unless, of course, it happened to be sitting in a shallow pond, in which case it could hold its majestic neck out to its full length. 6 FT FT.

Quick Facts. Elasmosaurus (/ ɪ ˌ l æ z m ə ˈ s ɔːr ə s,-m oʊ-/;) 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. 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. The first specimen was discovered in 1867 near Fort Wallace, Kansas, US, and was sent to the American paleontologist Edward Drinker Cope, who named it E. platyurus in 1868. Elasmosaurus Was Not a Dinosaur. 46 FT FT. 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.Another one of the most interesting facts about Elasmosaurus was that it was also incapable of moving its head like a snake.
