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 ...
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.
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 ...
Dinosaurs that lived in the Ross Dependency, a part of Antarctica within the Realm of New Zealand, include the tetanuran Cryolophosaurus.The Ross Dependency, unlike the Chatham Islands, is not actually part of New Zealand, and this is why it is excluded from the list above until sufficient evidence shows that it entered what was the sector of Gondwana that is now New Zealand.
