Yangchuanosaurus was a large carnivorous dinosaur that once terrorized the floodplains of China during the Jurassic period. It was similar in size to its American cousin Allosaurus, another large predator.

Yangchuanosaurus dongi
gchuanosaurus was relatively large as a carnivorous dinosaur. It was at the top of the chain of its area, as its prey were the sauropods Mamenchisaurus and Omeisaurus as well as the stegosaurids Chialingosaurus, Toujiangosaurus and Chungkingosaurus. Its massive tail was almost half its length, as it had a bony knob on its nose and multiple hornlets and ridges, making it slightly resemble Ceratosaurus.
