Vitosaura is an abelisaurid theropod dinosaur that lived in what is now Argentina. It was a medium sized bipedal carnivore reaching around 6 m in total body length. Though only known from the pelvic girdle, Vitosaura likely had a blunt rugose snout, and extremely short arms, as these are typical traits of abelisaurs.

Rhamphinion with Dilophosaurus in the background. While the pterosaur was identified as Dimorphodon by the artist, that genus is not known to have coexisted with Dilophosaurus, so the identity is here changed to its closest contemporary relative, which is possibly which was meant to begin with.
