Corosaurus is an extinct genus of pistosauroid known from Wyoming of the United States. The holotype measured about long, while larger specimens would have belonged to individuals measuring more than long.
==History of discovery== Corosaurus is known from the holotype UW 5485, a partial skeleton which includes the skull. 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.
