Corosaurus is an extinct genus 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]
History of discovery
Corosaurus is known from the holotype UW 5485, a partial skeleton which includes the skull . [1] Later, the referred specimens YPM 41030-41068, FMNH PR 135, FMNH PR 1368-1369, FMNH PR 242-246 and FMNH PR 1382-1383 were described by Glenn William Storrs in 1991. All specimens were collected in Jackson Canyon, Natrona County , from the Chugwater Group of the Alcova Limestone Formation , dating to the late Olenekian stage of the late Early Triassic , about 247.4-245 million years ago . [4]
Etymology
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]
