Tyrannosaurs—meaning"tyrant lizards"—were a family of large, carnivorous dinosaurs which lived in North America, Europe and Asia near the end of theTyrannosaurs tended to have massive skulls with large teeth and walked using their two long legs.
When De Groot first came across the fossils, he found several skull fragments. By analyzing these bones, the paleontologists were able to identify several unique features, such as prominent vertical ridges running along the length of the upper jaw, enabling them to confirm the specimen as a new species.
