Sinraptor (/sɪnˈræptər/) is a genus of metriacanthosauridtheropoddinosaur from the Late Jurassic. The name Sinraptor comes from the Latin prefix "Sino", meaning Chinese, and "raptor" meaning robber. The specific name dongi honours Dong Zhiming. Despite its name, Sinraptor is not related to dromaeosaurids (often nicknamed "raptors") like Velociraptor. Instead, it was a carnosaur distantly related to Allosaurus.[1]Sinraptor and its close relatives were among the earliest members of the Jurassic carnosaurian radiation. Sinraptor still remains the best-known member of the family Metriacanthosauridae,[2] with some older sources even using the name "Sinraptoridae" for the family.[1]

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 Zhao Xijin in 1993.[1] Standing nearly 3 meters (9.8 feet) tall and measuring roughly 7.6 meters (25 feet) in length, two species of Sinraptor have been named. S. dongi, the type species, was described by Currie and Zhao in 1993. A second species, originally named Yangchuanosaurus hepingensis by Gao in 1992,[3] 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 Metriacanthosauridae.[2] Gregory S. Paul proposed that S. dongi would reach 8 metres (26 ft) in length and 1.3 metric tons (1.4 short tons) in body mass,[4] while Holtz estimated it to be 8.8 metres (29 ft) in length.[5]
The dentition of Sinraptor was very similar to that of Allosaurus and indicated that it likely would have preyed upon medium-sized dinosaurs such as stegosaurs by using its blade-like teeth to inflict massive, fatal wounds.[6]
Sinraptor dongi skull specimen IVPP 10600 exhibits "a variety of gently curving tooth drags or gouges, shallow, circular punctures and one fully penetrating lesion." One rib was broken and healed via telescoping of its capitular shaft.[7]
