Like Tyrannosaurus, Tarbosaurus has a large head capable of crushing bone with up to five tons (10,000 pounds) worth of bite force, with ridges, notches, and grooves that provide Tarbosaurus with a unique jaw-locking mechanism (only shared with Alioramus, a relative of Qianzhousaurus). This feature perhaps evolved as an adaptation for dealing with the sauropods that it coexisted with in Mongolia. (Note: This Is Also My Remake of my old Chat In 2023 too :))
