Cryptoclididae is a family of medium-sized plesiosaurs that existed from the Middle Jurassic to the Early Cretaceous. 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. The earliest members of the family appeared during the early Bajocian, and they represented the dominant group of long-necked plesiosaurs during the latter half of the Jurassic.{{Cite journal|last1=Fischer|first1=Valentin|last2=Weis|first2=Robert|last3=Thuy|first3=Ben|date=2021-02-22|title=Refining the marine reptile turnover at the Early–Middle Jurassic transition|journal=PeerJ|language=en|volume=9|pages=e10647|doi=10.7717/peerj.10647|issn=2167-8359|pmc=7906043|pmid=33665003 |doi-access=free }}

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.{{Cite journal|author1=Ketchum, H. F. |author2=Benson, R. B.
