What’s wrong with the Teleosaurus and Plesiosaurus from Crystal Palace Park?

Much like the Mosasaurus, Plesiosaurus more than likely could not crawl onto land either. The actual animal itself is not known from very good remains and has sort of become a wastebucket taxon for different plesiosaurs, so I’ll have to be general with the critique. Basic physics tells us that the necks of plesiosaurs were too heavy to be lifted up like that, and were much more movable under the water, where it could be used to catch fish and squid. Beyond that, the body itself was probably not so stretched out and would’ve been more streamlined. Teleosaurus… actually looks very close to the real animal, although the snout wouldn’t have been so long and gharial-like.
