Ceratosaurus Facts

Ceratosaurus   >   Facts


Here are some facts about Ceratosaurus:
  1. Ceratosaurus was a genus of dinosaur (for more information see Ceratosaurus Classification).

  2. Five species of Ceratosaurus are currently known: Ceratosaurus dentisulcatus, Ceratosaurus ingens, Ceratosaurus magnicornis, Ceratosaurus nasicornis, and Ceratosaurus stechowi (for more information see Ceratosaurus Classification) - however many scientists dispute the validity of one or more these species.

  3. Ceratosaurus was a carnivore (ate meat).

  4. Ceratosaurus lived in the late Jurassic period, between approximately 156 million and 145 million years ago.

  5. Ceratosaurus lived in what is today North America, Africa, and perhaps Portugal.

  6. Ceratosaurus was probably about 15 to 20 feet (4.5 to 6 meters) long, and probably weighted around 1 ton.

  7. The most noteable feature of Ceratosaurus is the small horn on the end of its snout.

  8. Ceratosaurus had arms with four fingers (which is considered a relatively primitive feature).

  9. Ceratosaurus also had a very powerful tail. Othniel C. Marsh, who discovered the first fossils of the animal, thought it may have been a powerful swimmer because of its crocodile-like tail.

  10. There is still much to discover about Ceratosaurus. For example, because it has a mix of apparently primitive and advanced characteristics, it is not entirely clear which other dinosaurs it is related to.

  11. The first examples of Ceratosaurus were discovered in Dry Mesa Quarry in Colorado, and Cleveland Lloyd Dinosaur Quarry in Utah.

  12. The name "Ceratosaurus" means "horned lizard", and was chosen by its discoverer Othniel C. Marsh.
