Ceratosaurus was a medium sized carnivore that lived at the same time as the larger Allosaurus, in the Late Jurassic period. However, it also lived some millions of years before the emergence of the successful allosauroids, being of the more primitive four fingered Ceratosauria. What makes it different and distinctive is the large horn on top of its nose and the two horns over its eyes. The use of it has been debated and is most likely used for display (it can be hypothesized that keratinor soft tissue covered the horns), a weapon, or a special used for courtship battles. About 100 years ago, when it was first discovered, it was one of the most well-known dinosaurs. Other unusual features is that Ceratosaurus had a row of osteoderms running along its spine to the tail and four fingers on its hands, instead of the more common three among the other large meat-eaters during its time. This is typically an indication that this theropod is relatively primitive, whose ancestral relatives are from the earlier times of the Mid Triassic to Mid Jurassic periods when coelophysoideans and ceratosaurians were much more prevalent. Allosaurids and megalosaurian carnosaurs, both kinds tetanurans, were much more advanced, with greater speed and intelligence, as well as the ability in at least allosaurids to form packs.

It is probable that the Ceratosaurus ended up being sidelined by the Allosaurus in North America, as evidenced by the fact that Ceratosaurus is the rarest fossil theropod genus present in the magnificent Cleveland Lloyd Dinosaur Quarry. It probably became a prowler of the forest, using its terrifying dentition when ambushing smaller dinosaurs.

This information is given about Ceratosaurus in Jurassic Park: Explorer:

  • Ceratosaurus - smaller and more bird-like than its cousin Allosaurus.
  • Ceratosaurus was named for the single horn on its snout.
  • It was probably more of a scavenger, but may have also hunted aquatic prey.

Story

Creation

Ceratosaurus was successfully recreated by InGen in the Embryonics Administration lab on Isla Sorna in secret after the acquisition of InGen by Masrani Global Corporation and after the passing of the Gene Guard Act, alongside Corythosaurus, Spinosaurus, and Ankylosaurus.[2][3] The only known Ceratosaurus was parented and fed in captivity until InGen abandoned the lab and released it into the wild.

Like all of InGen's cloned theropods, Ceratosaurus had pronated wrists. The clones had a bright red head and a white body with black striping. The only known individual seen also had small horns over the eyes like a Ceratosaurus juvenile, as well as a longer and more pointed nasal horn like a Triceratops instead of the more rounded bump-like horn of the original Ceratosaurus, and was quite a bit larger than the original, with it was 3 meters in height rather than 2 meters and 9.2 meters in length rather than 8.5 meters.[4][1]

Being bred illegally and long after the Isla Nublar Incident, it was not planned to be an attraction in Jurassic Park.[5]

In the wild

After being cloned and experimented on for a period of 9 months in the late 90's, the unnamed InGen personnel set the dinosaur free alongside the other illegally bred dinosaurs.[3]

Being created illegally and against the knowledge of InGen or Masrani higher ups, it is unknown if the Ceratosaurus and the other new dinosaurs were affected by or were even bred to include the lysine deficiency that affected the original dinosaurs. It is also unknown how many Ceratosaurus lived on the island, but the one known specimen was known to live in the northern portion of the island.[2]

Isla Sorna Incident (2001)

A Ceratosaurus was found on a riverbank by the survivors of the 2001 incident on Isla Sorna.

A Ceratosaurus encountered Dr. Alan Grant and the Kirby family on a riverbank when they were digging through Spinosaurus dung in search of a satellite phone. At first, the humans thought it would attack them, but instead it went away, having been deterred by the Spinosaurus dung that was on them.[2]

Jurassic World: Camp Cretaceous

A Ceratosaurus came face to face with Darius and Kenji in a watering hole.

It is revealed that there were some Ceratosaurus on Isla Nublar at least some time after the destruction of Jurassic World in 2015. However, for unknown reasons, they were not among the dinosaurs mentioned in the park's promotional materials.

The Ceratosaurs on Isla Nublar had two different colors, the first of which corresponded to the Ceratosaurus from Jurassic Park III, while the second was gray. It's not known whether this this is due to gender dimorphism, but if so, the red Ceratosaurus is probably the male, as male animals are often more conspicuously colored than females.

A Ceratosaurus was killed by a hybrid dinosaur in Isla Nublar, the Scorpios Rex.

Darius and Kenji run into a gray Ceratosaurus in the episode Salvation. They thought it would attack them, but it went away to drink water at the watering hole. Later, a red Ceratosaurus attacks the whole group but was warded away by a flare shot by Mitch and Tiff.

In View from the Top a red Ceratosaurus is killed by the Scorpios rex, and its corpse is later dragged away.

Post Isla Nublar Incident (2015)

By the year 2018, Ceratosaurus had apparently been subjected to cruelty sometime before 2018, although it remains unknown if there are any surviving populations remaining.[6]

Behind the scenes

Jurassic Park III Ceratosaurus concept art.

In the script for Jurassic Park III Carnotaurus was originally supposed to be the dinosaur that the group encountered at the Spinosaurus dung site.[7] This could be why the Ceratosaurus in Jurassic Park III has a color scheme similar to the Carnotaurus in Disney's Dinosaur that was released a year before. Its color scheme is also similar to Ceratosaurus in the toy line Die-Cast: Jurassic Park (see the "Toys" tab for a picture). In Jurassic Park III, the Ceratosaurus was a modified T. rex model according to model supervisor Ken Bryan on the DVD commentary.[citation needed]

Trivia

  • The Jurassic Park III Ceratosaurus color scheme also seems to used for the Level 30 Ceratosaurus in Jurassic Park: Builder (see the "Games" tab for a picture).
