The fossil includes the complete upper jaw of the dinosaur and all the teeth are still intact. The remains also include the backbone, the foot, hips, and skull of the animal, according to KU News . Based on the appearance of the fossil, there's a high likelihood that it's that of a baby tyrannosaur. However, there's a possibility it's that of another carnivorous dinosaur.
Remains Are Most Likely That Of A Tyrannosaurus Rex
University of Kansas Biodiversity Institute's David Burnham revealed that the teeth from the fossil suggest that the remains are that of a T. rex ,
Researchers can compare the remains of T. rex and they also have the fossils of the dinosaur's younger version on loan.

In 2003, Gregory Erickson of Florida State University received permission to slice a fibula of the dinosaur remains and compare it to the bones of T. rex. Rex and is not a Nanotyrannus.
The fossil uncovered in Montana could not shed light on this controversy. Burnham and the researchers involved in the study, which includes Kyle Atkins-Weltman, wants to publish the results of the investigation in the next few months.
The University of Kansas researchers also believe that there could be more dinosaur remains in the Hell Creek Formation, aside from the baby Tyrannosaurus rex, and they will be back to excavating the site by summer.
