Referred species

Sinraptor is a genus of theropod dinosaur from the Late Jurassic. The name Sinraptor comes from the Latin suffix. "Sino", meaning "Chinese", and "Raptor" meaning "Thief". The specific name dongi honours Dong Zhiming. Despite its name, Sinraptor is not related to dromaeosaurids (often nicknamed "raptors") like Velociraptor. It probably even hunted the largest dinosaur to walk on Asia; Mamenchisaurus.


The holotype specimen of Sinraptor was uncovered from the Shishugou Formation during a joint Chinese/Canadian expedition to the northwestern Chinese desert in 1987, and described by Philip J. Currie and Xian Zhao in 1994. Standing nearly 3 meters tall (10 ft) and measuring roughly 7.6 meters (25 ft) in length, two species of Sinraptor have been named. S. dongi, the type species, was described by Currie and Zhao in 1994.

A second species, originally named Yangchuanosaurus hepingensis by Gao in 1992, may actually represent a second species of Sinraptor. Whether or not this is the case, Sinraptor and Yangchuanosaurus were close relatives, and are classified together in the family Sinraptoridae. The skeleton of Sinraptor hepingensis (formerly referred to Yangchuanosaurus) is on display at the Zigong Dinosaur Museum, Zigong , China.

In the Media

  • Sinraptor appeared in Dinosaur Revolution, where they are depicted living only alongside Shunosaurus. In reality, they would co-exist with both Mamenchisaurus & Shunosaurus. A pair of Sinraptors hunted a toxinated young male Shunosaurus named Shroomo, but are both defeate. One killed and the other driven off.
  • They also appear in Planet Dinosaur, where one juvenile tries to attack and eat an Epidexipteryx, but fails. But when another, larger Epidexipteryx comes down to the ground, it attacks, kills, and eats it.
  • Sinraptor also appeared in the TV series, Ancient Earth, where it is depicted with feathers and is shown co-existing alongside Kulindadromeus, when the episode itself takes place in Siberia, Russia.
