Aucasaurus

Aucasaurus was a meat-eating dinosaur that roamed Argentina during the Late Cretaceous. Smaller than its cousin Carnotaurus, it had tiny arms with barely any fingers—almost like little nubs. One fossil shows skull damage, hinting this fierce predator might have gotten into a fight before it died.

• Belonged to the abelisaurid family, known for their short arms and strong legs.
• Lived in what is now Argentina's Anacleto Formation around 80 million years ago.
• Had one of the most complete abelisaurid skeletons found when discovered in 2002.
