Teleidosaurus is an extinct genus of carnivorous metriorhynchoid crocodyliform from Middle Jurassic (late Bajocian to early Bathonian stage) deposits of Normandy, France. The name Teleidosaurus means "Complete lizard", and is derived from the Greek Teleidos- ("complete") and σαῦρος -sauros ("lizard").
Discovery
The type species was named Teleosaurus Calvadosii by Jacques Amand Eudes-Deslongchamps in 1866; however, it was his son, Eugène Eudes-Deslongchamps who erected the generic name Teleidosaurus later in 1869 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. 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.
Classification
The only species within Teleidosaurus is the type species T. calvadosii. Both T. bathonicus and T. gaudryi where referred to Eoneustes. All species are from Calvados, Normandy of France. Phylogenetic analyses do not support the monophyly of Teleidosaurus. Once considered a metriorhynchid, Teleidosaurus was later recovered as non-metriorhynchid metriorhynchoid.
