趣味知識

Sinraptor was named in 1994 by Philip Currie and Zhao Xijin after a fossil was found in the Gobi Desert of China in 1987.3 1

Despite its name, Sinraptor is not a close relative of Velociraptor. It belongs to a different group called carnosaurs.1

A single Sinraptor tooth found in the same rocks is 10 cm (3.9 in) long. If it belonged to Sinraptor, that animal might have been up to 12 m (39 ft) long.1

The holotype skeleton of Sinraptor dongi is nearly complete but missing most of the tail and arms. It is kept at the Royal Tyrrell Museum in Canada.3 1

Sinraptor had a large air-filled hole in its cheek bone (jugal), which helped lighten its skull.3

One Sinraptor skeleton shows a broken rib that healed by telescoping, meaning the broken ends slid together. It also has tooth marks from other dinosaurs.1

Sinraptor lived about 160 million years ago, during the Oxfordian stage of the Late Jurassic.1
