Monolophosaurus

Monolophosaurus (MON-oh-LAW-foe-SORE-us) was a medium size Theropod dinosaur from the period. It was named for the single crest on top of its skull. The only known species, Monolophosaurus jiangi, measured 5 metres in length and weighed 1,500 pounds. Monolophosaurus may have hunted in packs to take down Sauropods like Mamenchisaurus, although no evidence have been found of Monolophosaurus hunting in packs, it may have hunted in packs like many other Theropods. Monolophosaurus was a crested dinosaur, but it wasn't closely related to other crested dinosaurs like Dilophosaurus. In fact, it was closer related to the more advanced tetanurans, like Allosaurus.
