Summary:
- This article describes the discovery of a new species of dinosaur called Meraxes gigas, a giant carnivorous theropod that lived in what is now Argentina during the Late Cretaceous period, around 90 million years ago.
- Meraxes gigas was a massive predator, measuring up to 10 meters long and weighing an estimated 4 tons, making it one of the largest known carnivorous dinosaurs.
- The discovery of this new dinosaur species provides important insights into the evolution and diversity of large theropod dinosaurs during the Late Cretaceous period, just before the mass extinction event that wiped out the non-avian dinosaurs.
