The bottom was dominated by large Large fish known to have inhabited the sea include the bony fishes They had four flippers used for swimming; and their long tail is also believed to have at least 18 vertebrae. Elasmosaurus was a genus of Plesiosauria that lived around 80.5 million years ago. A bizarre creature whose body was dwarfed by its long, thin neck and tail, Elasmosaurus swam using four flippers. 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. The cited variability in the number of heads on the neck ribs arises from his inclusion of Welles took issue with White's classification in his 1943 revision of plesiosaurs, noting that White's characteristics are influenced by both preservation and Carpenter's 1997 phylogenetic analysis of plesiosaurs challenged the traditional subdivision of plesiosaurs based on neck length. Elasmosaurus 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. Elasmosaurus es un género de plesiosaurio conocido por un cuello increíblemente largo.

It also had four paddles which helped it glide though the water like a dolphin would today. Elasmosaurus Kingdom Animalia Phylum Chordata Class Reptilia Superorder Sauropterygia Order Plesiosauria Family Elasmosauridae Genus Elasmosaurus Species E. platyurus (Cope, 1868) Characters Elsie Miscellaneous This is a very large type of Plesiosaur. This would help them digest their food the way seals, sea lions, and crocodiles do today.Just like other Plesiosaurs the Elamosaurus lived in the water for it’s entire life, only coming to the surface for air. The articular surfaces of the vertebrae in the front of the neck were broad oval, and moderately deepened, with rounded, thickened edges, with an excavation (or cavity) at the upper and lower sides. It was given its name that very year a name which means ribbon lizard. It would occasionally dive down to the seabed in shallow areas to find rounded pebbles. During the Late Cretaceous Period when Elasmosauruspaddled the earth, the Western Interior Sea sat upon the land of … Habitat Just like other Plesiosaurs the Elamosaurus lived in the water for it’s entire life, only coming to the surface for air.
A more recent date of 26,000 BP is considered less reliable. They had four flippers used for swimming; and their long tail is also believed to have at least 18 vertebrae.Its aquatic adaptation restricted it to the marine environment. After its discovery in 1868, the first scientists to study this animal thought the long neck was its tail and so put the head at the wrong end. Elasmotherium is an extinct genus of large rhinoceros endemic to Eurasia during the Late Pliocene through the Pleistocene, existing from 2.6 Ma to at least as late as 39,000 years ago in the Late Pleistocene. 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. There is a lot to know about these neat Plesiosaurs.
It appears looking at the fossils that the dinosaur had to have gotten air from the surface like a dolphin. Elasmosaurus had a long neck (around 25 feet) with 71 neck vertebrae that offered a great flexibility to control their head. It was first discovered in the spring of 1868 by Edward Drinker Cope in Western Kansas in the United States. They had strong jaws and very sharp teeth. 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 spent all its time in the water, often cruising coastal waters for shoals of fish.
It is believed that their population went extinct around 65 million years ago during the Cretaceous–Tertiary (K–T) extinction event.
