  Although its teeth were sharp and plentiful, they were not large so Yangchuanosaurus was unable to inflict the kill through its bite alone. Yangchuanosaurus likely also used the massive claws on its hindlimbs to slash and tear. As the largest late Jurassic theropod in China, Yangchuanosaurus was a powerfully-built dinosaur, in many ways resembling the fearsome Allosaurus. The long low crests over the snout may have been an indication of health to a potential mate.
