As in the Tyrannosaurus rex, fossil remains of a dinosaur with a strong jaw, a large head, huge legs and scarce arms have been found in China. Like him, he was a predator with a high degree of specialization. However, it had characteristics that differentiated it: He lived 60 million years before T. rex, five times smaller than him.

Raptorex kriegstein has been baptized by paleontologists at the University of Chicago, who have studied footprints. The group leader has stated that Raptorex is in an old branch of the dinosaur group that gave dinosaurs of the species T. rex.
