It is a giant carnivorous dinosaur that lived in the late Cretaceous period, belonging to the theropod dinosaurs. Fossils were mainly found in Argentina and are one of the largest terrestrial carnivores discovered in South America. Huge in size, comparable to the famous Tyrannosaurus rex. The head is large, with strong jaws and sharp teeth, suitable for tearing prey. The forelimbs are relatively small, while the hind limbs are very developed, supporting its massive body. The tail is long and heavy, and may play an important role in balancing the body and making quick turns. Living in the late Cretaceous period approximately 97 to 93 million years ago, he was the top predator in the ecosystem at that time. They feed on other large dinosaurs.
