There were two types of tyrannosaurids in North America-the northern type (including Albertosaurus, Gorgosaurus, and Daspletosaurus ) and the southern type (including Teratophoneus and Lythronax ). Southern-type North American tyrannosaurid This idea is correspondent with the hypothesis proposed by paleontologist Phil Currie that Tyrannosaurus’s ancestor was actually Tarbosaurus. ![]() rex specimens are 68 million years old.Īccording to a study from 2013 by paleontologist Steve Brusatte, Tyrannosaurus rex was most likely an invasive species in North America, probably arriving from Asia. All specimens are dated to be approximately 70 million years old, or slightly less. Tarbosaurus remains were excavated from the Nemegt formation in Mongolia. The fact that these two animals are so similar has led some paleontologists to conclude that Tarbosaurus may just be a junior synonym of Tyrannosaurus, although not many agree with this hypothesis today. rex), a proportionally longer and narrower skull (resulting in eye sockets that are further back in the skull, giving Tarbosaurus a considerably smaller field of binocular vision), and a less massive body. The only notable morphological differences between it and Tyrannosaurus are that Tarbosaurus has proportionally smaller front limbs (yes, there are dinosaur species with even smaller arms than T. Tarbosaurus is probably the closest relative of Tyrannosaurus discovered so far. There are three main contestants: (1) Tarbosaurus bataar, (2) southern-type North American tyrannosaurid, or (3) Daspletosaurus torosus. rex’s ancestor? What dinosaur species has the honor to be called “the King’s” grandparent? However, one important question hasn’t yet been answered-who was T.

The oldest human ancestor remains we have found is called Lucy - and she is estimated to be an amazing 3.2 million years old. One of the earliest prehistoric caveman remains we have found is called “Ötzi the Iceman” and he was estimated to be over 7,000 years old. We are also digging on the names of the raptors from Jurassic World: Blue, Delta and Echo.īlue, Delta Charlie or Echo?
