Microceratus is a genus of small ceratopsian dinosaur that lived in the Cretaceous period in Asia. It would have used its sharp beak to bite off the leaves or needles. In the first Jurassic Park novel, they spend most of their time in the trees.

It became known as Microceratops, but that name was already occupied by a wasp with the same name. The replacement name Microceratus was created by Mateus in 2008 for the type specimen.

Wikipedia has a more detailed and comprehensive article on Microceratus




A herd of Microceratus.

Microceratus was successfully recreated by InGen for Masrani Global Corporation's new dinosaur park Jurassic World. Their skin color came in olive, dark red, turquoise, or all of the above. Each individual had at least one or all of these colors arranged in a unique pattern. They seem to be able to swap between being a quadruped and a biped. They grew a foot longer than the original dinosaur and weighed 10 more pounds. They had low intelligence and would mistake litter of park visitors for food.[1] It lives in the Cretaceous Cruise and is possibly the smallest dinosaur in the Jurassic World park.

Jurassic World: Fallen Kingdom

While not in the trailers so far, it has been revealed that there are surviving Microceratus populations on Isla Nublar, but they and many other dinosaurs will now face an impending danger in the form of an erupting volcano.


Jurassic Park

Microceratus appears in the novel under its old scientific name Microceratops. It was a free-roaming addition to the park. However, they may mainly reside in Sauropod Swamp.

There were exactly 22 Microceratops on Isla Nublar while the park was still in control. At the end of the novel, only 13 remain. They're encountered by the group when Lex points out the dinosaurs are eating berries while riding a raft along the jungle river.

Some editions of the novel (like the Novel bundle) accidentally replace its name with that of Callovosaurus.

Behind the scenes


Microceratus in the Jurassic World storyboard.

In the Jurassic World storyboard, Microceratus was supposed to live in the Gentle Giants Petting Zoo. They were also shown to be a bit aggressive, as show in the storyboard when they are seen jumping on a man's face.[2]

The icon for Microceratus seen on the Holoscape and the Jurassic World website comes from a size diagram of Microceratus from the website DinoPit.
