[1] Sinraptor and its close relatives were among the earliest members of the Jurassic carnosaurian radiation.
[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 1994.
[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.
[9] Sinraptor dongi skull specimen IVPP 10600 exhibits "a variety of gently curving tooth drags or gouges, shallow, circular punctures and one fully penetrating lesion."
