The Triceratops is commonly known as the "three-horned face." This dinosaur, which lived during the Late Cretaceous period, is characterized by its distinctive three facial horns and a large bony frill at the back of its head. The horns were likely used for defense against predators, and possibly in mating displays or social interactions. Despite its formidable appearance, the Triceratops was herbivorous, primarily feeding on low-lying vegetation. Its fossils have been discovered in North America, and it remains one of the most recognized dinosaurs in popular culture.
