Meet Tarbosaurus

Tarbosaurus bataar was a large tyrannosaur from Late Cretaceous Asia. Its fossil record includes the Nemegt Formation of Mongolia. The skull had deep, powerful jaws, but it was not identical to the head of Tyrannosaurus rex. Detailed comparisons help distinguish these animals rather than treating every huge tyrannosaur as the same dinosaur in a different place. [S1]

Viewed from the side, both skulls look deep. Seen from above, the Tarbosaurus skull is narrower, with less abrupt widening toward the rear. Its lower-jaw bones also fit together in a way the researchers interpreted as producing a more rigid jaw. These are anatomical observations and functional interpretations: they explain how parts could handle biting forces, rather than preserving a direct measurement of a living bite. [S1]

The main Tarbosaurus skull studied in this research was only partly preserved, so preparation, comparison and restoration were important. A scientific reconstruction can be informative without making every part equally certain. The skull gives useful evidence about identity and feeding capability, while nests, parental care, courtship and coordinated hunting remain unresolved in the sources reviewed here. Understanding these distinctive bones helps separate preserved anatomy from a more uncertain whole-body restoration. [S1]
