- The Triceratops was a North
- American herbivore that lived in the
- late Cretaceous period, some 100
- million years ago.
- Its dentition consisted of one row
- of teeth on each side of its mouth
- specialized for slicing, rather than
- grinding plant food.
- It had two long (up to six feet)
- horns above its eyes, and a shorter
- horn (up to three feet) above its
- beaked mouth. Its rear legs had four
- hooved toes and its forelegs had
- five toes with hooves on the three
- larger, central toes. Triceratops
- grew to a length of 24 feet and
- weighed up to 20000 pounds.
- Triceratops may have been a herd
- animal, and was certainly prey for
- the terrible Tyrannosaurus.
- Triceratops was a member of the
- Ceratopsia -- the last of the major
- Dinosaurian groups to appear -- and
- was one of the last surviving
- dinosaurs.
- Ceratopsians appear to have
- descended from the East-Asian
- Protoceratops, which had a fringed
- neck, but no horns. Relatives of the
- Triceratops include Monoclonius
- which had a single horn like that
- of a rhinoceros, and Styracosaurus
- ("Spike Lizard") which, in addition
- to a horn on the nose, had six
- protective horns arrayed on its
- crest.
- Triceratops fossils have been
- discovered in Montana, Wyoming and
- Colorado.^
