Many Triceratops appear in The Rite of Spring segment of Fantasia as adults and babies. They walk in herds to find food. many were seen running when the Tyrannosaurus Rex attacks, 1 of which ran into a lake to swim away as 3 Brachiosaurs dived down to avoid the T-Rex as well. During the drought at the end of the segment, Triceratops walks with other dinosaurs to find more food and water, but all of them end up going extinct from starvation and dehydration.

There are currently two species of Triceratops known from the fossil record, T.horridus and T.prorsus.
At one point in time, Triceratops was often believed to be a younger version of another ceratopsian, Torosaurus. This was mostly due to the fact that they were in the same subgroup of ceratopsians and had lived in the same fossil formations, though Torosaurus was more common in the south and Triceratops being more common in the north. However, a study by Yale University published in 2012 proved that they are distinct species.
In the Hell Creek Formation, a specimen of Triceratops preserved with skin impressions indicates that it may have been covered with quills or bristles in addition to scales. A similar type of pelage was found on Psittacosaurus, a distant relative.
Triceratops was supposed to be on Disney Dinosaur as it was seen in the concept art but was cut.
