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. © TotalDino · CC BY 4.0 · Wikimedia
