Yangchuanosaurus is a member of the allosaurid family. It is slightly smaller than Allosaurus, but has more teeth. Like most classic large predators, Yangchuanosaurus has two strong legs, smaller arms and a large head. It is big enough to prey on most of the plant-eaters of the period -and other meat-eaters for that matter - including some sauropods.

No one has spotted one yet, but some palaeontologists think that Yangchuanosaurus might have a head crest - maybe only the males. This crest could be used in courtship displays, much like a peacock's tail, or to intimidate male rivals.
