Plesiosaurus is the archetypical genus of Plesiosauria and the first to be described, hence lending its name to the order. Conybeare and De la Beche coined the name for scattered finds from the Bristol region, Dorset , and Lyme Regis in 1821. [ 6 ]
A new genus was named, Plesiosaurus. The generic name was derived from the Ancient Greek πλήσιος, plèsios, "closer to" and the Latinised saurus, in the meaning of "saurian", to express that Plesiosaurus was in the Chain of Being more closely positioned to the Sauria, particularly the crocodile, than Ichthyosaurus, which had the form of ...
Elasmosaurus differed from all other plesiosaurs by having 72 neck vertebrae; more may have been present but were later lost to erosion or after excavation. Only Albertonectes had more neck vertebrae, 76, and the two are the only plesiosaurs with a count higher than 70; more than 60 vertebrae is very derived (or "advanced") for plesiosaurs. [14 ...
This list of plesiosaurs is a comprehensive listing of all genera that have ever been included in the order Plesiosauria, excluding purely vernacular terms.The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that ...
All plesiosaurs, including Thalassiodracon were faunivorous, but widely ranged in their diets. Animals such as ammonites, cephalopods, and other invertebrates were often found in plesiosaur remains. [20] With the bones of dinosaurs and pterosaurs being found in plesiosaur remains, these animals are also possibilities for their diets. [20]
The thigh bone was longer than the upper arm, which is unusual for an elasmosaurid, and the right thigh bone was broken and healed. [ 1 ] Terminonatator is significant because of its late age, its inclusion of a skull with most of a skeleton, and its nature as an elasmosaurid (the remains of short-necked plesiosaurs are more common in ...
Plesiosaur fossils can be found all over the world, Marx said. The combination of both smooth and scaly skin is unusual, and it had different functions, the researchers said.
Another of the specimens Linder described was a well-preserved skull (GPIT RE/3409), [2] also from the University of Tübingen, preserving a sclerotic ring (the set of small bones that support the eye), only the fourth time these bones had been reported in a plesiosaur. [13]
