Kosmoceratops (76 mya)

Kosmoceratops was a remarkable representative of horned dinosaurs that lived about 70 million years ago, in the Late Cretaceous, in what is now the state of Utah (USA). This large herbivorous dinosaur reached approximately 4.5 meters in length and weighed around 2.5 tonnes.

The most striking feature of Kosmoceratops was its unusual skull. Like other ceratopsians, it possessed three primary horns—one above the nose and two above the eyes. However, it was the bony frill that made it truly unique: it was decorated with numerous additional horns and protuberances, curved in various directions. Two small horns even projected from the cheek region. In total, this dinosaur bore up to fifteen horns of different shapes and lengths—one of the highest counts known among ceratopsians.

Researchers suggest that this elaborate “crown” served not only a defensive function but also a display role, possibly helping males attract mates or intimidate rivals.

Kosmoceratops fed on vegetation. Using its powerful beak, it cropped leaves and shoots, while teeth positioned deep within the jaws efficiently ground tough, fibrous plant material. It cannot be ruled out that it occasionally consumed other organic matter—such as small animals or carrion—but such behavior was likely rare and did not form a significant part of its diet.
