(SALT LAKE CITY, UT) – Fossils similar to a T-Rex found in southern Utah have proven that the ancestors of the most famous of all dinosaurs lived much earlier than researchers assumed. During an unveiling at the Natural History Museum of Utah on Wednesday, scientists argued that the fossils were 10 million years older than any T-Rex they’ve found before. The dinosaur, which they named “Lythronax argestes,” was found in the Grand Staircase-Escalante National Monument. At more than 80 million years old, it’s likely that the tyrannosaur died during the late Cretaceous period, which ended 70 million years ago.
