Quick Summary

Kosmoceratops was a plant-eating dinosaur from the Cretaceous Period, belonging to the group known as ceratopsians. These dinosaurs are characterized by a bony frill at the back of their skull and a unique upper beak bone called a rostral.1

Kosmoceratops is notable for its ornate skull, featuring a broad frill and hooks projecting forward from the top of its head, which some paleontologists consider the most elaborate of any known dinosaur. It was a close relative of Triceratops but possessed a more decorated frill and lacked the large horns found on some other ceratopsians.12
