Corosaurus is an extinctgenus of pistosauroid known from Wyoming of the United States.[1][2] The holotype measured about 1.65 m (5.4 ft) long, while larger specimens would have belonged to individuals measuring more than 4 m (13 ft) long.[3]
Corosaurus was first named by Ermine Cowles Case in 1936 and the type species is Corosaurus alcovensis. The specific name is derived from the name of the Alcova Limestone Formation, in which the holotype was found.[1]
Classification
Corosaurus was placed in its own family, Corosauridae, which named by Oskar Kuhn, in 1961.[4] After a revision of the holotype and referred material of Corosaurus, Olivier Rieppel found Corosaurus to be the sister-taxon to a clade comprising Cymatosaurus, Pistosaurus and Plesiosauria.[2]
