mapusaurus roseae

Mapusaurus was a formidable and massive carnivorous theropod that roamed what is now Argentina around 95 million years ago, during the Late Cretaceous period. It is believed to have reached lengths of up to 33 feet (10 meters) and weighed between 3 to 5 tons, making it one of the largest theropods of its time. Distinguished by its long, slender body, sharp teeth, and powerful jaws, Mapusaurus was an apex predator in its environment, preying on large herbivorous dinosaurs. What sets Mapusaurus apart from many other large theropods is evidence suggesting it may have exhibited social behaviors, with fossilized remains of multiple individuals found in close proximity to each other, hinting that it might have hunted in packs, much like modern-day wolves. This behavior would have provided significant advantages in taking down large prey, such as sauropods, which were abundant in the region. Its discovery has offered important insights into the social dynamics and hunting strategies of Cretaceous theropods.
