Aucasaurus (meaning "Auca Lizard", after the Auca Mahuevo in South America.) is an abeliosaur which lived in South America during the late Cretaceous period. It was closely related to Carnotaurus, which lived in the same place and same time as Aucasaurus, although it was half the size. Aucasaurus ate eggs. They often hunted in packs to overtake nesting dinosaurs. They can't bend their elbows, so their arms always remained straight. The only discovered fossil of an Aucasaurus had a fracture on it's head, which might have occured during a fight.
