Szechuanosaurus ("Szechuan lizard") is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic.
Szechuanosaurus is at times regarded as a nomen dubium[5][6] due to the lack of diagnostic features in the fossilized teeth upon which the genus is based.
[7] Although the fossils are too fragmentary for confident identification, Szechuanosaurus is often interpreted as a medium-sized allosaurid[8] or perhaps a metriacanthosaurid,[6] capable of reaching lengths of around 7.3 meters.
Later, Dong Zhiming et alii (1983) described it, and assigned it to Szechuanosaurus campi[13] The affinities of this skeleton are uncertain, and it has only been briefly described.
[16] The third species is Szechuanosaurus zigongensis, named by Gao Yuhui in 1993 for an almost complete skeleton, specimen ZDM 9011.
