This web-page explains children about Triceratops. Who were these creatures? Triceratops are plant eating (herbivorous) dinosaurs which lived in Late Cretaceous period.
This was about 65 to 68 million years ago. That's how his skeleton looks like -
Triceratops had three horns on its head. No wonder why it was called Triceratop then. "Triceratop" means "three horned face" in Greek.
So, how big was this dinosaur? Scientists think that it was about 8 to 9 meters in length (25-30 feet) and about 3 meters (10 feet) in height. Overall, it was an impressive dinosaur with a very large skull. Here is another picture of this dinosaur walking around in the Late Cretaceous period.
When in danger, Triceratops could give a fight using their horns as dangerous weapons. Their biggest enemy was the mighty T-rex (http://www.michaellandia.com/Trex.html). This is a picture of the fight between a triceratop and an T-tex which happened 65 million years ago.
There were other predators looking for an easy prey. One had to be careful in the late Cretaceous period! Other predators, such as this Pterodactyl (http://www.michaellandia.com/Pterodactyl.html), could be hunting in one of the evenings of a late Cretaceous preriod.
Luckily, a little baby triceratop noticed the danger and alterted all family. When prompted, Triceratops would give a good fight. The strong horns of Triceratops in such fights were very handy and dangerous.
Here is another picture of the animal.
