Zhuchengtyrannus

Zhuchengtyrannus (meaning "Zhucheng tyrant") was a genus of tyrannosaurids that lived in the Late Cretaceous of Shandong, China. Its only species is Zhuchengtyrannus magnus.

 Description 
Zhuchengtyrannus, a large theropod, is estimated to be comparable in size to both Tarbosaurus and Tyrannosaurus.

The size of Zhuchengtyrannus is estimates in 10 and 11 meters (33 to 36 ft) in lenght, with a weight of 4.1 and 5 metric tons (5.9-6 shorts tons). A specimen recently discovered in 2025, containing a vertebra that appears to belong to Z. magnus, is comparable in size to large Tyrannosaurus rex specimens. It is estimated to have measured 12 meters (39 ft) and weighed 8 tonnes (8.5 short tons).

Zhuchengtyrannus is often depicted in life as resembling its close relatives, such as the Asian Tarbosaurus and the North American T. rex.

 Classification 
The firts fossil of Zhuchengtyrannus was been found in China, in Zhucheng Formation. He was named firts as a species of Tyrannosaurus genus, like Tyrannosaurus zhuchengensis.

In 2010, the same discoverer renamed it Tarbosaurus zhuchengensis, considering it a second species within the same genus. However, that same year, it was reclassified as a species belonging to a new genus, and thus Zhuchengtyrannus magnus was born.

He is believed to belong to the family Tyrannosauridae, belonging to the tribe Tyranosaurini, which includes T. rex itself and its closest relatives.
