       Vespersaurus is a genus of noasaurine theropod dinosaur that lived in South America during the Late Cretaceous.‭ ‬At the time of its description Vespersaurus is notable for two reasons.‭ ‬First is that the Vespersaurus holotype fossils were discovered in an area that back in the early Cretaceous was part of a huge desert,‭ ‬suggesting that Vespersaurus was more of a desert dwelling dinosaur.‭ ‬Second is that the third toe of the foot is enlarged and bore all of the body weight.‭ ‬This might reflect a specialist adaption to its environment and/or lifestyle.
