Pentaceratops
Pentaceratops was a large, four-legged herbivorous dinosaur that lived during the Late Cretaceous period. Its name, meaning "five-horned face," reflects its distinctive features, although it actually possessed three prominent horns—two above the eyes and one on the nose. Pentaceratops could grow to lengths of 18 to 20 feet (5.5 to 6 meters) and weighed approximately 2.75 tons (2.5 metric tons). A notable characteristic of this dinosaur was its large bony frill, which extended from the back of its head and served to anchor jaw muscles rather than provide protection.
Despite its size and formidable horns, Pentaceratops faced threats from predators such as Tyrannosaurus rex. Its frill, while impressive, featured large holes that limited its protective capabilities. Instead, the dinosaur relied on its sharp horns and powerful beak for defense. Fossil evidence of Pentaceratops has primarily been uncovered in New Mexico, marking it as an important specimen in the study of dinosaur evolution. Although little is known about its breeding habits, Pentaceratops remains a fascinating subject for paleontological research.

Pentaceratops
Pentaceratops was a four-legged plant eater. It had three horns which grew up from its head depsite its name which means five. It also had a large frill or plate of bone which stood up above its neck.
Kingdom: Animalia

Species: Sternbergii
Pentaceratops was a large dinosaur. An adult could grow to a length of 18 to 20 feet (5 1/2 to six meters). It weighed 2 3/4 tons (2 1/2 metric tons). At the top of its head behind its eyes was a large plate of bone called a frill. It was not used as protection by the animal but instead to connect the animal's jaw muscles.
Pentaceratops had a long head with three large, brown horns on it. One was located above each eye and the other, shorter horn, at the tip of the animal's nose. Pentaceratops had a small round body. It walked on four, thin legs. The front legs were short so when the animal walked, its head was close to the ground. Pentaceratops had a horny beak like that on a turtle with very powerful jaws. Its skin was covered by large, round bumps called tubercles.
Pentaceratops was an herbivore, or plant eater. Its strong jaw muscles allowed it to eat many different types of vegetation. This included grape leaves, figs, cottonwoods, viburnum, palms, and pines.
When attacked by a large, meat-eating predators like Tyrannosaurus-rex, Pentaceratops was not able to use the frill on its neck for protection. The large, thinly covered holes in the frill made it useless against a large enemy. This frill was used to connect the animal's jaw muscles but not to fight. The animal could defend itself with its sharp horns and beak.
Very little is known about the breeding habits of Pentaceratops.
Fossil remains of Pentaceratops have been found in New Mexico. Pentaceratops are extinct.
