A dinosaur with three horns

One of the most recognisable dinosaurs is the mighty Triceratops. Its name means “three-horned face”, which describes its most famous features: two long horns above its eyes and a smaller one on its nose. It also had a large bony frill at the back of its head.

Triceratops lived around 68 to 66 million years ago, during the late Cretaceous period. At that time, North America, where they mostly lived, was full of forests, rivers and many different types of dinosaurs.

Triceratops was one of the last dinosaurs to live on Earth before the mass extinction about 66 million years ago, when a huge asteroid is thought to have hit the planet, dramatically changing the climate.

A powerful plant-eater

Unlike predators, Triceratops was a plant-eating dinosaur. Scientists believe it used its strong beak to bite plants and its powerful teeth to chew tough leaves and branches.

The dinosaur could grow up to 9 metres long and weigh about 6 to 12 tonnes, which is roughly the weight of two elephants. Its huge skull, which included the horns and frill, could grow more than 2 metres long.

Those horns were probably useful for defence. During the late Cretaceous period, dangerous predators lived in the same environment, including the famous Tyrannosaurus Rex. The horns probably helped Triceratops protect itself from attacks.

Some scientists also think the horns and frill may have been used in fights between Triceratops, just as many modern-day animals do today.

Did Triceratops live alone?

Scientists are still learning about how Triceratops lived. Some discoveries suggest these dinosaurs may have lived alone or in small groups. Unlike some other plant-eating dinosaurs, there is no strong evidence that they travelled in huge herds.

Like other dinosaurs, Triceratops reproduced by laying eggs. Scientists believe a female probably laid a clutch of eggs in a nest, although the exact number is not known. The baby dinosaurs would have hatched and then grown quickly.

Young Triceratops probably looked a little different from adults. Their horns and frills were smaller, and these features likely grew larger as the dinosaur matured.

Fun facts about Triceratops

Here are some interesting facts about this famous dinosaur:

• The name Triceratops means “three-horned face.”
• Its skull is one of the largest skulls of any land animal ever discovered.
• The frill at the back of its head may have helped protect its neck.
• Triceratops lived at the same time as T. rex.
• Some Triceratops fossils show injuries on the horns, which may have come from fights with other dinosaurs.
• Its beak was similar to the beak of a modern parrot, but much bigger.
• The first Triceratops fossils were discovered in the late 1800s.
• Hundreds of fossils have been found, making it one of the best-known dinosaurs.
