Ceratosaurus

Ceratosaurus was a predatorial Theropod Dinosaur that lived during the late Jurassic Period in the American West. It sported a nose crest that may have glown a bright color during mating season to attract members of the opposite sex.it was relatively small and often hunted in pairs(male and female). often one of the pair was hiding, when the mate drove the prey to the hiding one. at late jurassic, allosaurus took their place in America, but there still were some in Europe.

In Jurassic Park
Ceratosaurus was in the third Jurassic Park movie, making a brief appearance on the river bank, sniffing the dung-covered main characters, then walking away in disgust. you stink.

In Operation Genesis
Ceratosaurus is also available as a two-star small carnivore, appearing as it does in the movie, and hunting larger herbivores in packs. In the game as well as the movie, this dinosaur is shown to be smaller than it was in real life, though it is possible that in the movie that the one encountered was not yet fully grown.

Real Information
Ceratosaurus lived during the Late Jurassic period, and would have hunted in packs alongside Allosaurus, the apex predator of the time. Ceratosaurus measured around 20 feet and had a horn which was used to attract mates. Ceratosaurus was said to weigh half its larger relative, A. fragilis. Ceratosaurus means "horned lizard".

On a different note, Ceratosaurus was recycled from a T. rex.
