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 has 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 Park franchise[]

Monolophosaurus was among the many species of dinosaurs that appeared in the Dinopedia section of Jurassic Park Institute.


The Monolophosaurus clones were gray, yellow and green variants. Like all of InGen’s theropods, they had pronated wrists. The clones also seem to have a thin stretch of skin crossing their nostrils, giving it the appearance of having two pairs of nose holes. These Monolophosaurus were also observed for their preference for small prey and solitary nature.


According to Darius, Monolophosaurus is believed to be a solitary hunter. However, it is possible that this carnivorous dinosaur's behavior of hunting in packs could have been influenced by the presence of Scorpios rex, a predator that caused fear and disrupted the natural behavior of many dinosaurs. Alternatively, it is also plausible that the genetic makeup of the Monolophosaurus clone could have contributed to its pack hunting tendencies, which Darius may not have been aware of at the time.

Monolophosaurus has demonstrated a patient hunting strategy, where they wait for their prey to gather together or for favorable conditions to arise. They have been observed targeting smaller prey, including humans, by patiently waiting for them to fall asleep or for larger individuals to separate from the group, thus making them easier targets for the predator's hunting approach.


Jurassic World: Camp Cretaceous[]

Monolophosaurus was one of the dinosaurs cloned for Jurassic World. At some point, they survive after the fall of the park and were encountered by park survivor Darius Bowman. At another point, a Monolophosaurus was caught and killed by a Tarbosaurus.

Season 3[]

Casa De Kenji[]

Darius' group encountered a Monolophosaurus on their way to Kenji's dad's penthouse, but Darius reassures the group it is of no threat and moves on. As the kids search the penthouse, a mob of Monolophosaurus follow them to the building and break in via an air vent. As the dinosaurs search the building, two of them find Ben Pincus, Sammy Gutierrez, and Yasmina Fadoula in one of the building's hallways, forcing them to climb into an air vent to escape, but the dinosaurs manage to follow them inside. The group manages to briefly lose the dinosaurs and get into the penthouse's garage, but the Monolophosaurus eventually catch up, forcing the group to hide within the limos. Having just taken the gas out of all but one of the limos, the kids are forced to sneak through the limos and past the dinosaurs until they reach the final limo, and use it to drive off and escape the mob.

Meanwhile, another Monolophosaurus breaks into the penthouse suite, where Darius, Brooklynn, and Kenji Kon were waiting, and forces them to retreat down the elevator shaft. As they climb down, two more Monolophosaurus ambush them from the air vents. One of the dinosaurs causes Brooklynn to fall to the bottom of the shaft before falling itself and falling unconscious until Darius falls on top of it. As it prepares to attack them, Kenji saves them by a sculpture he was caring onto the dinosaur's head, knocking it unconscious again. Exiting the penthouse, the group are attacked by more Monolophosaurus until Ben, Yaz, and Sammy find them with their commandeered limo, and the group's Ankylosaurus Bumpy slams into the predators, leaving them disoriented. As the kids escape, Darius voices his confusion over the more social behavior shown by the Monolophosaurus.

A Shock to the System[]

After being informed about the existence of a wild hybrid, the Scorpius rex, Darius theorizes the hybrid's existence is what's causing the behavioral changes in Monolophosaurus and other dinosaurs.

Stay on Mission[]

Two Monolophosaurus enter Dr. Henry Wu's private lab and investigate the building until Brooklynn lures them in by banging an umbrella against a pipe. The dinosaurs attack her captors, mercenaries Hawkes and Dawson as well as Henry Wu himself until Brooklynn uses the opportunity to attempt an escape, which draws the attention of the Monolophosaurus towards her. Pursued by the dinosaurs, she quickly finds the building's exit and shuts it on the approaching predators.

It is unknown whether these dinosaurs were either rescued off the island or went back into extinction by the eruption of Mount Sibo on Isla Nublar.
