Qianzhousaurus (meaning "Qianzhou lizard") is a genus of tyrannosaurid dinosaur that lived in Asia during the Maastrichtian age of the Late Cretaceous period. There is currently only one species named, the type species Qianzhousaurus sinensis, which is a member of the tribe Alioramini and most closely related to Alioramus, the only other known alioramin.
Described as lacking advanced tail feathers and long "hind wings", unlike other paravians, but this may be an artifact of preservation [41] Epidexipteryx: 2008 Haifanggou Formation (Middle Jurassic, Callovian) China: Supported four long feathers coming out from an abbreviated tail Equijubus: 2003 Xinminbao Group (Early Cretaceous, Albian) China
In all examples, the evidence described consists of feather impressions, except those genera inferred to have had feathers based on skeletal or chemical evidence, such as the presence of quill knobs (the anchor points for wing feathers on the forelimb) or a pygostyle (the fused vertebrae at the tail tip which often supports large feathers).

Hence, the clade Alioramini consists of three species, namely Alioramus altai, Alioramus remotus, and Qianzhousaurus sinensis. [2] Some researchers have tried to synonymize Qianzhousaurus with Alioramus, [9] but many others maintain that they are separate genera. Alioramini is usually considered to be a part of the Tyrannosaurinae subfamily ...

The Asiatyrannus holotype is about half the length of the contemporary Qianzhousaurus. However, the holotype of Asiatyrannus did not belong to a skeletally mature individual, and as such, it would have been larger when fully grown. Nevertheless, it had probably passed through the life stages of most rapid growth, and other tyrannosaurines in ...
