The most well-known dinosaur on this list has to be the Triceratops. This dinosaur lived in North America during the Late Cretaceous Period roughly 68 million years ago. The Triceratops gets its name from the Ancient Greek words for “three-horned face.” Triceratops is unique in that it is one of the last known dinosaur species that are not related to birds.
The first Triceratops fossil was uncovered in Denver, Colorado in 1887. Triceratops is known for the large frill and three horns on the top of its skull. Its stocky four-legged body closely resembles the modern rhinoceros. These large animals could be upwards of thirty feet long and ten feet tall. Triceratops was extremely heavy, weighing between 13,000 and 26,000 pounds. Because their heads were low to the ground, paleontologists believe that these herbivores feasted on low-growing plants.
