This gives it its dinosaur name, which means 'three-horned face'. By studying a dinosaur’s teeth, scientists can estimate what type of food they likely ate. We know that this species was herbivorous because they had flattened teeth perfect for grinding plant matter. Researchers also believe that these dinosaurs fed on low vegetation, because their heads were rather low on their body.Marsh, O.C. (1887). "Notice of new fossil mammals".

It was not only an adorable dinosaur but also very well protected against predators, which made it easier for him to walk around in herds without having to fear that much about what he would encounter. The cladogram below follows Longrich (2014), who named a new species of Pentaceratops, and included nearly all species of chasmosaurine. [47] Chasmosaurinae Holtz, Thomas R. Jr. (2012).
