Cryptoclidia is a clade of plesiosaurs.
Cryptoclidia was named and defined as a node clade in 2010 by Hilary Ketchum and Roger Benson: the group consisting of the last common ancestor of Cryptoclidus eurymerus and Polycotylus latipinnis; and all its descendants.[1]
The following cladogram follows an analysis by Benson & Druckenmiller (2014).[2]
