PentaceratopsThe Pentaceratops is an herbivorous dinosaur that lived in North America approximately 75 million years ago, during the Late Cretaceous period. It could reach up to 8 meters in length and was recognizable by its large frill and five horns. Interesting fact: its wide frill likely served as a defense mechanism against predators, but also to attract attention during mating displays. Its spectacular horns made it one of the most impressive ceratopsians.
