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. ![]() ___________________________________________________________________

It was likely just slightly larger than D. tororus holotype. That's not even close to be T. rex sized theropod. |

I have question. Have you ever seen my scale chart, which is in this topic? Do you think if Zhuchengtyrannus was 11 m with only ~1.1 m skull, would't be skull to small? Edited by 7Alx, Jan 11 2013, 09:04 PM.

I seen your comparison, but it seems that Dave Hone was able to make out an 11-meter tyrannosaur based on known Zhuchengtyrannus remains http://archosaurmusings.wordpress.com/2011/04/03/so-just-how-big-was-zhuchengtyrannus/ Also, do tyrannosaurids even have a consistent skull:body ratio like spinosaurids? Or do they vary greatly? |

I agree this one is a very tough call - since they are so very similar. If I had to guess I would go 50.1 for Tarbosaurus, and 49.9 for Zhuchengtyrannus. |

If the maxilla is proportionally smaller, which isn't ruled...Maybe Edited by 7Alx, Jan 12 2013, 12:19 AM.

The two would be extremely closely matched and it would depend entirely on the individuals particularly as its unknown how powerfully built Zhuchengtyrannus was which means its impossible to know whether it was stronger or weaker than its very close relatives and until then the safest guess is that it was the same build. |

Who sais spinosaurids had a consistent ratio? I don't have the impression that they have, there is some difference between Edited by theropod, Feb 10 2013, 03:31 AM.

oouuups, I meant to write Baryonyx but somehow I often mean baryonyx and type irritator. after all, irritators postcranium isn't even known... |

tarbosaurus wins since its skull is significantly larger.

So, Zhuchengtyrannus was probably only Daspletosaurus-sized? At parity it's going to be very difficult just to think of a winner due to them being so similar, but if Tarbosaurus really was THAT much larger.......

The outcome of this heavily depends on which animal was bigger, as they were both large tyrannosaurids. Unless one animal has a good size advantage, I'm going with 50/50 on this one. |

this was originally posted by 7Alx. according to this, tarbosaurus is the larger animal. |
