Vitosaura was named in 2025, making it one of the newest dinosaurs discovered.3

Its fossils were found in the Los Llanos Formation, which is about 83 to 72 million years old.3

Vitosaura is the first named theropod dinosaur from the Cretaceous of La Rioja Province.1

The only known specimen includes parts of the backbone, hip bones, and other fragments.1

Scientists are not sure exactly how Vitosaura is related to other abelisaurids, but it might be closely related to dinosaurs from India and Madagascar.1
