Cretaceous plesiosaurs of Europe

Brancasaurus (meaning "Branca's lizard") is a genus of plesiosaur which lived in a freshwater lake in the Early Cretaceous of what is now North Rhine-Westphalia, Germany. With a long neck possessing vertebrae bearing distinctively-shaped "shark fin"-shaped neural spines, and a relatively small and pointed head, Brancasaurus is superficially similar to Elasmosaurus, albeit smaller in size at in length as a subadult.

Aptychodon (meaning "unwrinkled tooth") is an extinct genus of plesiosaur from the Late Cretaceous of the Czech Republic. The type species is A. cretaceus.
