Albertonectes

Albertonectes vanderveldei, a large Elasmosaurine Plesiosaur from the late Cretaceous. This Elasmosaurine Plesiosaur has the longest neck of all plesiosaur, about 7m neck on 11.6m long animal. Albertonectes feed on fish and cephalopods. But their diet are likely more diverse, as Elasmosaurs have been found with small mosasaur, pterosaur, and shark in their belly
