Nasutoceratops


Nasutoceratops (Na-su-to-seh-ra-tops), Wandering Horned Face, lived in the late Campanian of western North America. It looks very different, representing a new type of centrosaurine dinosaur with a short nose horn and brow long-horns. The Kaiparowits Formation in Utah where it was discovered has a different dinosaur population from the better-known finds in Montana and Canada.

Genera and Species

Classification: ‬Ornithischia,‭ ‬Ceratopsia,‭ ‬Ceratopsidae ‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬

Species: N. titusi.

Characteristics Nasutoceratops had horns, which measured 3.5 feet. It was a deep-snouted dinosaur with a set of long U-shaped brow-horns, curved over the eyes. There was a small horn on the oversize nose, a simple frill without hooks, and spikes decorating the frill. The headgear likely evolved by natural selection to reflect a survival strategy that differed from its northern relatives.

Size Length 15 feet. Weight 2.5 tons.


Behavior

Nasutoceratops was slow-moving, wandering in big herds for protection and feeding on plants in a swampy bayou with many other dinosaurs near the coast. They used their "headgear" to compete for mates, locking those curved horns in battles for dominance competitions and defense from predators.


History of Discovery

Described by Sampson, Lund, Loewn, Farke and Clayton, in 2013. It is known from a fragmentary skull, vertebrae, a left forelimb and a right forelimb.

Paleoenvironment Found in southern ranges of Laramidia, an isolated landmass that formed when a shallow sea flooded central North America during the Cretaceous. It lived in the southern Utah coastal swamps about 75 million years ago. Based on the difference in dinosaurs, there was some type of geographic or environmental barrier separating the northern parts of Laramidia that kept the dinosaur populations separate.
