Ferrucutus ("Horned Iron-Hide") is a descendant of the Ceratopsidae family, which includes creatures such as the famous Triceratops.


It is about 24-36 feet (7.2 to 10.8 meters) long and stands about 10 feet tall. Physically, it resembles its ancestors; it has a stout, powerful body with strong, elephantine legs. The basic layout of the skull is also similar; it consists of a powerful, parrot-like beak capable of slicing through tough vegetation, horns on the head, and a large frill at the back of the head which has two large openings in it, covered by skin (these become brightly colored during the mating season). However, like all ceratopsians, Ferrucutus has its own unique array of horns, having far more than any other species. Two medium-size horns and several more smaller ones sprout from the snout, and the crest also sports several large horns, similar to the extinct ceratopsian Styracosaurus. Ferrucutus also has a bony bulge between the nasal horns, similar to Pachyrhinosaurus. Bulls have the longest horns, and they increase in length by age. The two small horns facing towards each other atop the crest often cross each other in old males. Ferrucutus resemble an Achelousaurus with spikes on its face.Ferrucutus are herbivores, grazing in small herds across the lowlands and in the waterways of the island. They often use their horns to uproot trees with leaves too high to reach. The horns are also used by males in the breeding season; they often fight with each other over the females' attention, interlocking their horns and pushing each other with full force. Injuries and deaths are not uncommon. The horns are also used to intimidate and sometimes attack predators. Coupled with the creature's aggression, these formidable weapons cause many predators, apart from the mighty Vastatosaurus rex, to think twice before attacking adult Ferrucutus. When attack does come, the herd forms a protective circle around the youngsters, effectively shielding them from any possible danger.


  • The Ferrucutus that appears in the extended cut of the Peter Jackson version was made as a homage to the Stegosaurus attack from the 1933 film, but instead of being knocked out by the bombs like in the original, the ceratops was shot to death.
  • The ceratops' design was based mostly on a Styracosaurus with minimal influences from Paleoscene era mammals.
