They lived during the Late Cretaceous period of the Mesozoic era, 68-65.5 million years ago.
It looks more detailed and scientifically accurate at the Prehistoric Party 2013, whereas the frill and claws looked different in other appearances.
The Triceratops in the game resembles Torosaurus, a close relative of Triceratops. This could be because some consider Torosaurus to be an adult Triceratops, a hypothesis that has been recently put into doubt.
Their name means three-horned face, but the exact species, Triceratops horridus means horrid three-horned face.
They are 9 meters (27 feet) long and 3 meters (9 feet) tall.
They seem to have some feathers or quills along their back. This is may have based on the fact that an early relative of Triceratops, Psittacosaurus, was discovered with quills, though it is unknown if Triceratops had them as well.
In the Prehistoric Party 2013, there are 4 Triceratops eggs: Orange, Aqua, Lavender and Red. The Red is the biggest of them.
