Paul the Pentaceratops

~One of the many Pentaceratops sternbergii~

Nahaal B. T4

Pentaceratops sternbergii mainly lived in Northwestern New Mexico, North America. Paul the Pentaceratops was one example of this interesting species. He is sometimes referred to as “Five-Horned Face” because of the five horns on his face; a feature Pentaceratops are well known for. He lived approximately 75 - 65.5 million years ago, which was during the Late Cretaceous Period and the End of the Mesozoic Era; the Age of Reptiles. The cause of his and his extended family's extinction is unknown, but scientists have discovered many aspects of how he lived.

He was a herbivorous organism, which means that he only ate plants. Since the location in which he lived in had a limited amount of plants at the time, it is most likely that he ate the predominant plants, such as: ferns, cycads, and conifers. Also, he benefitted from the five horns on his face to charge into his enemy, just like rhinoceroses. Furthermore, he used them to help retrieve plants from branches. Then, he would use his incredibly sharp teeth to shred it, and finally eat it. In addition, since they laid eggs and he became a parent for a short period of his life, he would use his horns to protect his babies from any possible harm—before and after they hatched.

Height Compared to Average Human

Paul, like the rest of his species, was approximately 6 - 7 meters long and 4 meters tall. This is about 2 times the height of an average 1.8 meter human being. He weighed around 6.5 tons. Pentaceratops were the second heaviest dinosaurs of all of the ceratopsians.
Paul was a ceratopsian, which is a group of animals that have three qualifications: he was from the Cretaceous Period, has a bony frill on the back of his head, and has a unique upper beak bone (called the rostral). In addition, he has five horns on his face—one horn on his snout, one above each eye, and one on each side of his neck frill (the back of his skull). As a result of the protective horns, he had few enemies. The behavior of Pentaceratops was very close to that of rhinoceroses. These organisms are very closely related to Triceratops, which lived in the same time period, so they are also nonexistent. Pentaceratops had the largest known skull ever found, and were the last dinosaur species to evolve before the Cretaceous-Tertiary extinction.
