Vespersaurus is a genus of noasaurine theropod dinosaur from the Late Cretaceous period, found in the Rio Paraná Formation in the Paraná Basin, Brazil. The type and only species is V. paranaensis, which would have lived in the giant prehistoric Botucatu Desert. The taxon is notable for its distinct, functionally monodactyl foot anatomy, where the singularly large third digit would have borne most of the weight while walking.[1]
