Pentaceratops, or “five-horned” in Latin, is a genus that includes herbivorous ceratopsid dinosaurs from North America’s late Cretaceous Period. The fossils of this animal were discovered for the first time in 1921. However, the genus was first named in 1923 after its type species, Pentaceratops sternbergii was described. Pentaceratops lived between 76 and 73 million years ago. Its remains were mostly found in New Mexico’s Kirtland Formation. A total of twelve skulls and skeletons were found, which means that anatomical knowledge of Pentaceratops has been fairly extensive. Titanoceratops was later named after an exceptionally large specimen. This is due to its more complex morphology, similarity to Triceratops and lack of unique characteristics.

Pentaceratops measured 6 meters (20 ft) in length and weighed approximately 5 metric tons (5.5 short tonnes). It had a small nose horn, long brow horns and long horns at the jugal bones. The skull was very long with triangular triangular hornlets at the edges.
