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 ...
Plesiosaurus (Greek: πλησίος (plesios), near to + σαῦρος (sauros), lizard) is a genus of extinct, large marine sauropterygian reptile that lived during the Early Jurassic. It is known by nearly complete skeletons from the Lias of England.
The fact that the osteology of the plesiosaur's neck makes it absolutely safe to say that the plesiosaur could not lift its head like a swan out of water as the Loch Ness monster does, the assumption that air-breathing animals would be easy to see whenever they appear at the surface to breathe, [146] the fact that the loch is too small and ...

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 ...
Ark: Survival Evolved (stylized as ARK) is a 2017 action-adventure survival video game developed by Studio Wildcard. In the game, players must survive being stranded on one of several maps filled with roaming dinosaurs , fictional fantasy monsters, and other prehistoric animals, natural hazards, and potentially hostile human players.
Plesiosaurs were represented by two groups in the Kristianstad Basin; long-necked elasmosaurids and short-necked polycotylids. [5] The last comprehensive review of the plesiosaur fauna in the Kristianstad Basin was done by paleontologist Per-Ove Persson in the 1960s and his taxonomy is still used with caution, pending a much-needed new review.

Like many plesiosaurs, elasmosaurids are easily recognizable by their compact, streamlined bodies, long paddle-like limbs, short tails, proportionately small heads, and very elongated necks. [2] The oldest known representative, Jucha , dating from the Hauterivian stage of the Lower Cretaceous , [ 1 ] would have measured 5 m (16 ft) long. [ 6 ]
