Mapusaurus was a large theropod dinosaur that lived during the Late Cretaceous Period, approximately 97–93 million years ago. It was discovered in Argentina, within the Huincul Formation of Patagonia, a region that preserved many large South American dinosaurs.
Mapusaurus belonged to the family Carcharodontosauridae, a group of giant predatory dinosaurs that included Giganotosaurus and Carcharodontosaurus. It had a long, narrow skull filled with blade-like teeth designed for slicing flesh, making it an effective predator of large herbivorous dinosaurs.
Reaching an estimated length of 10–12 meters (33–39 feet) and weighing several tonnes, Mapusaurus was one of the largest meat-eating dinosaurs known from South America. It had powerful hind legs, a long balancing tail, and strong arms with clawed fingers.
A large number of Mapusaurus fossils were discovered together at the same site, leading scientists to suggest that it may have hunted in groups. This behavior may have allowed it to attack enormous prey such as Argentinosaurus, one of the largest dinosaurs ever discovered.
