“Now this dinosaur is something special. Well, they’re all special, but this one stands out because of the horns on top of its head. It’s called Ceratosaurus. It kinda looks like a slightly smaller T. rex. But its bite is probably about the same.”Claire Dearing

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.
