Summary:
- The article discusses the discovery of a new species of dinosaur called Meraxes gigas, which was a large carnivorous dinosaur that lived in what is now Argentina during the Late Cretaceous period, around 90 million years ago.
- The Meraxes gigas had a large, heavily-built skull and strong jaws, suggesting it was a top predator in its ecosystem. Researchers believe it could have grown up to 9 meters long and weighed over 4 tons.
- The discovery of this new dinosaur species provides important insights into the diversity and evolution of large carnivorous dinosaurs in South America during the Late Cretaceous period, just before the mass extinction event that wiped out the dinosaurs.
