Tarbosaurus bite marks have also been identified on hadrosaur and sauropod fossils, but theropod bite marks on bones of other theropods are very rare in the fossil record. [65] A 2020 study involving stable isotopes found that Tarbosaurus primarily hunted large dinosaurs in its environment, most notably titanosaurs and hadrosaurs. [66]
The Subashi Formation (Chinese: 苏巴什组) is a Late Cretaceous (Campanian to Maastrichtian) [1] formation from the Xinjiang Autonomous Region of western China. [2] Initially described by Dong Zhiming in 1977, the formation contains remains of Tarbosaurus which were initially described as a separate taxon Shanshanosaurus huoyanshanensis.

Researchers are now proposing a surprising location for the birthplace of dinosaurs, based on the locations of the currently oldest-known dinosaur fossils, the evolutionary relationships among ...
Thomas Holtz found Appalachiosaurus to be an albertosaurine in 2004, [5] but his more recent unpublished work locates it just outside Tyrannosauridae, [18] in agreement with other authors. [19] The other major subfamily of tyrannosaurids is the Tyrannosauridae , including genera such as Daspletosaurus , Tarbosaurus , and Tyrannosaurus .
The skulls and skeletons of enormous carnivorous dinosaurs found in the Cretaceous rocks of the Gobi Desert are also among the exhibits at the museum, and they are on show in a separate exhibition hall. The main attraction is two skeletal mounts of the Tarbosaurus, an Asian relative of the well-known Tyrannosaurus rex. The present understanding ...
Many phylogenetic analyses have found Tarbosaurus bataar to be the sister taxon of T. rex. [61] The discovery of the tyrannosaurid Lythronax further indicates that Tarbosaurus and Tyrannosaurus are closely related, forming a clade with fellow Asian tyrannosaurid Zhuchengtyrannus, with Lythronax being their sister taxon.
Fossils have been found in different formations in what is now east Asia and western North America. While the Asian alioramins are the basal most group of the tyrannosaurines, the geographic placement of albertosaurines and other eutyrannosaurian tyrannosauroids found in North America suggests greatly the tyrannosaurines are North American in ...
