Teleidosaurus is an extinct genus of carnivorous metriorhynchoid crocodyliform from Middle Jurassic (late Bajocian to early Bathonian stage) deposits of Normandy, France.[1][2] The name Teleidosaurus means "Complete lizard", and is derived from the Greek Script error: No such module "Lang".- ("complete") and Script error: No such module "Lang". -sauros ("lizard").

Restoration

The type species was named Teleosaurus Calvadosii [Sic] by Jacques Amand Eudes-Deslongchamps in 1866;[3] however, it was his son, Eugène Eudes-Deslongchamps who erected the generic name Teleidosaurus later in 1869[4] for Teleosaurus calvadosii. Teleidosaurus joberti from the Great Oolite Formation is a junior synonym of T. calvadosii. T. calvadosii is known from the plastotype NHM R.2681, a complete skull and mandible and from NHM 32612, the plastotype of T. joberti, fragmentary right mandible. The holotype lost during the Second World War.[5][6] However, some plastoholotypes of T. calvadosii were saved in the Natural History Museum, London, (NHMUK PV R 2681), the National Museum of Natural History, France, and the Museum of Nancy.[6]

Classification

The only species within Teleidosaurus is the type species T. calvadosii. Both T. bathonicus and T. gaudryi where referred to Eoneustes.[5] All species are from Calvados, Normandy of France. Phylogenetic analyses do not support the monophyly of Teleidosaurus.[1][7] Once considered a metriorhynchid, Teleidosaurus was later recovered as non-metriorhynchid metriorhynchoid.[6]
