Trivia

 * Triceratops was incorrectly shown to have legs that sprawled out like those of a lizard. In real life, Triceratops had legs directly underneath its body like those of a rhino.
 * 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.
