Tarbosaurus bataar Tarbosaurus belongs in the subfamily Tyrannosaurinae within the family Tyrannosauridae, along with the earlier Daspletosaurus, the more recent Tyrannosaurus and possibly Alioramus. Animals in this subfamily are more closely related to Tyrannosaurus than to Albertosaurus and are known for their robust build with proportionally larger skulls and longer femurs than in the other subfamily, the Albertosaurinae. Although many specimens of this genus have been found, little definite data was confirmed on the dinosaur as of 1986, though it was presumed to share many characteristics with other tyrannosaurids. The close similarities have prompted some scientists to suggest a possible link between the North American and Eurasian continents at that time, perhaps in the form of a land bridge. As with most dinosaurs, Tarbosaurus size estimates have varied through recent years. It could have been 10 meters long, with a weight of 4 to 5 - 7 tons. ![]() Zhuchengtyrannus magnus Zhuchengtyrannus (meaning "Zhucheng tyrant") is an extinct genus of carnivorous theropod dinosaur from the Late Cretaceous period. It is a tyrannosaurine tyrannosaurid which lived during the late Cretaceous period in what is now Zhucheng, Shandong Province of China. It is known from the holotype ZCDM V0031, a nearly complete right maxilla and associated left dentary (lower jaw, both with teeth) recovered from the Wangshi Group, dating to about 70 million years ago. It is one of the largest known Tyrannosaurid theropods, and the holotype has been estimated to have been 10–12 m (33–39 ft) in length and up to 6 short tons (5.4 t) in weight. The holotype dentary is slightly smaller than that of most specimens of Tyrannosaurus rex and slightly bigger than most of Tarbosaurus bataar, but significantly smaller than the corresponding bones of the largest Tyrannosaurus specimen ("Sue"). The dinosaur was found in an area that was a floodplain in the Cretaceous period and which contains one of the highest concentrations of dinosaur bones in the world. ![]() ___________________________________________________________________

Aren't they pretty much the same animal? |

They're too similar, and the size difference is too small to make a difference. 50/50 |

50/50 slightly leaning towards Tarbosaurus. |

tarbo imo, but it rather depends on the figures we take

They are mor or less the same animal, so it totally depends on the size. what we have of Zuchengtyrannus doesn´t indicate a particularly huge animal, at best comparable to small T. rex specimens... EDIT: And that of Tarbosaurus isn’t that huge either! Edited by theropod, Apr 14 2014, 02:09 AM.

Maybe this size comparison will help to decide. The Zhucheng skull is like only ~110 cm. Tarbosaurus holotype skull looks much bigger here. Also IGM 107/2 (1.22 m skull) would be bigger too. Zhuchengtyrannus might be comparable to PIN 551-3. Sorry guys but i couldn't find better Zhuchengtyrannus skull reconstruction. http://img51.imageshack.us/img51/7567/tarbosauruszhucheng.png |
