Sinosaurus, also known as Sinosaurus triassicus, is known to have inhabited present-day China and the fossil remains were found in Lufeng Formation. It belongs to the Dinosauria, Theropoda, and Neotheropoda clade. It existed in the Early Jurassic period. No information is available about the habitat of this theropod.

Not a lot is known about the appearance of this dinosaur but whatever is known about this animal is based on the fossils that consisted of two upper jaws (maxillary) fragments, a lower fragment that consisted of three teeth, and four maxillary teeth.

The teeth of this dinosaur were known to be compressed laterally and have serrations at their anterior and posterior edges and are curved towards the back.

The braincase of this specimen is known to be almost complete and lacked only a few bones. It is related to a similar specimen named Dilophosaurus sinensis and both of them were known to have crests.

Dilophosaurus sinesis and Sinosaurus triassicus can be differentiated on the basis of the vertical groove that was there on the lateral premaxilla adjacent to the maxilla. Based on the jaws and teeth structure and reconstructed skeleton, it has been recorded that the diet of this animal was carnivorous or it was a scavenger.

The name and description of this dinosaur were done by Dong Zhinming who is considered to be the father of Chinese vertebrate paleontology. The fossil material found in the red beds that were initially named Sinosaurus was later reassigned as Jingshanosaurus.

Sinosaurus means 'Chinese lizard'. The skeleton of this specimen is known to be the only dilophosaurid that is known from the entire braincase.

It is quite fascinating to discover more about this theropod and if you are interested, read about Atrociraptor and Ludodactylus, too.
