Teleosaurus (from Greek: τέλειος téleios, 'perfect' and Greek: σαῦρος saûros, 'lizard')[1] is an extinct genus of teleosaurid crocodyliform found in the Middle Jurassic Calcaire de Caen Formation of France.[2] It was approximately 3 metres (10 ft) in length.[3] The holotype is MNHN AC 8746, a quarter of a skull and other associated postcranial remains, while other fragmentary specimens are known.[4] The type species is T. cadomensis,[5] but a second species, T. geoffroyi may also exist.[6] It was previously considered a wastebasket taxon, with many other remains assigned to the genus.[7][4]
