Monolophosaurus was a medium sized Theropod from the Middle Jurassic period. It was named for the single crest on top of its skull. The only known species, Monolophosaurus jiangi, measured 7.5 metres in length and weighed 1,565 pounds. Monolophosaurus may have hunted in packs to take down Sauropods like Mamenchisaurus, although no evidence have been found of Monolophosaurus hunting in packs. 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.

Jurassic World: Camp Cretaceous

It is revealed that there were some wild Monolophosaurus on Isla Nublar some at least some time after the destruction of Jurassic World in 2015. Darius didn't seem to be surprised about the Monolophosaurus, so it can be assumed that he already knew about them, although the species was not mentioned in any of the official brochures for the park.

Monolophosaurus appeared in the third season of Jurassic World: Camp Cretaceous. Its shadow is cast as it roams in a location around the corner in a long hallway where Ben, Sammy, and Yasmina are. There was a mob of Monolophosaurus in Camp: Cretaceous Season 3. At least 9 Monolophosaurus were cloned for Jurassic World with grey, yellow and green variants, although it's not known whether this is a gender dimorphism. Darius said that they are loners and keep to themselves.

It is not known whether the species was survived on Isla Nublar until 2018. If so, it is also unknown whether they became extinct in the Mount Sibo eruption or were among the dinosaurs brought to the Lockwood Manor.
