Cryptoclididae
Cryptoclididae is a family of medium-sized plesiosaurs that existed from the middle Jurassic to the early Cretaceous period. They had long necks, broad and short skulls and densely packed teeth. They fed on small soft-bodied preys such as small fish and crustaceans.

Classification
In 2010, two supposed late Cretaceous members of the group were reclassified as other kinds of plesiosauroids. Kaiwhekea was reclassified to Leptocleididae, and Aristonectes was transferred to Elasmosauridae.[3]

gollark: That confirms nothing, however.
gollark: It would be really stupid to do so, from basically all perspectives.
gollark: And I won't negotiate with you on this, see.
gollark: As I said, you merely need to utilize an I-Q modulator to generate a 72THz phase-shft-modulated gamma ray beam.
gollark: Again, I do not negotiate with people within the set of real numbers.
