Tarascosaurus (“Tarasque lizard”) is a genus of, perhaps abelisaurid, theropod dinosaur from Late Cretaceous of France.
The holotype PSL 330201 was found in the Fuvelian Beds, dating from the lower Campanian. It consists of the upper part of a thigh bone, 22 centimetres (8.7 in) long. PSL 330202, consisting of two dorsal vertebrae, was made a paratype; these bones may belong to the same individual. Referred was PSL 330203, a damaged tail vertebra. The femur, with an undamaged length estimated at 35 centimetres (14 in), indicates a body length of two and a half to three metres. Some fossils from Spain were also referred to the genus.
In 2003 Oliver Rauhut concluded that Tarascosaurus itself was also a nomen dubium because the material was not diagnostic.
Tarascosaurus was placed in the Abelisauridae in 1991. It was then seen as the only known abelisaurid from the Northern Hemisphere apart from Betasuchus of the Maastrichtian of the Netherlands. However, in 2003 Ronan Allain et al. concluded that the type lacked any uniquely abelisaurid traits.
