Ceratosaurus was a carnivore (meat-eater) that lived in North America, Africa, and possibly Portugal, during the late Jurassic period, about 156 to 145 million years ago.

Ceratosaurus was about 15 to 20 feet (4.5 to 6 meters) long and may have weighed up to 1 ton.

Ceratosaurus can be recognized by the short horn on its snout, its massive tail, and its four-fingered hands (a primitive configuration). Ceratosaurus was first discovered by Othniel C. Marsh who choose the name which means "horned lizard", referring to the horn on the animal's nose. Marsh speculated that Ceratosaurus was a good swimmer because of its crocodile-like tail.

The earliest examples of Ceratosaurus were found in Cleveland Lloyd Dinosaur Quarry in Utah and Dry Mesa Quarry in Colorado. At least four, and perhaps as many as six, distinct species Ceratosaurus are now known from the fossil discoveries to date.

There is still many issues to research and debate about Ceratosaurus, not least of which is how exactly to classify it. One of the mysteries about the creature is that it has a mix of advanced and primitive characteristics, and it is not entirely clear which other dinosaurs it is related to.

Ceratosaurus Facts

Here is a summary of some of the key facts about Ceratosaurus:
  1. Ceratosaurus was a genus of dinosaur.

  2. "Ceratosaurus" means "horned lizard" (after the horn on the animal's snout). The name was chosen by Othniel C. Marsh in 1884.

  3. Ceratosaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Ceratosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.

  4. Ceratosaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Ceratosaurus was not itself an ancestor of birds).

  5. Ceratosaurus lived between about 156 million years ago and 145 million years ago, during the Jurassic period.

  6. Ceratosaurus lived in North America, Africa, and at least parts of Europe (there is some evidence that Ceratosaurus lived in Portugal).

  7. Ceratosaurus was a carnivore (meat-eater).

  8. Ceratosaurus was about 15 feet (4.5 meters) to 20 feet (6.1 meters) long.

  9. Ceratosaurus weighed up to 1 ton.
