Monolophosaurus was a medium size Theropod dinosaur from the Middle Jurassic 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.
Monolophosaurus is no. 010 of the Carnivore Twos that can be created in Jurassic Park III: Park Builder.
Monolophosaurus appears in Jurassic World: The Game. It originally wasn't in the game but since August 4, 2015 it can be created for the player's park by unlocking it in the Level 55 battle arena.
Monolophosaurus will be in Jurassic World: Alive.
A Monolophosaurus figure was released as part of the toy-line for Jurassic World: Fallen Kingdom, as part of the "Battle Damage" line. This is the first time it has ever physically appeared in any Jurassic Park toy set. A new repainted and retooled version of this figure will be part of the new "Savage Strike" assortment of the "Dino Rivals" line.
