Nasutoceratops (76 mya)

Nasutoceratops was one of the most unusual horned dinosaurs that lived in what is now Utah (USA). Its discovery in 2013 became one of the notable paleontological finds of the decade.

This powerful herbivorous dinosaur moved on four sturdy limbs. The broad pelvis indicates that the hind limbs were particularly well developed, helping to support its massive body. The tail of Nasutoceratops was relatively short, while its long, curved horns and large bony frill likely served as effective defensive structures. Although it was not especially fast, its defensive adaptations made it dangerous prey even for large predators.

Researchers were especially interested in its anatomy: numerous air-filled cavities were discovered within the nasal bones of Nasutoceratops. Such a structure, known as pneumaticity, had not previously been described in other known ceratopsids. Scientists continue to debate the function of these cavities — they may have reduced the weight of the skull or helped amplify sounds used in communication.

More than 75 million years ago, the region inhabited by Nasutoceratops consisted of an extensive floodplain with a network of river channels, lakes, and swamps, bordered by uplands. It was here that the famous Kaiparowits Formation developed — one of the richest paleontological sites in North America. Thanks to it, scientists have gained a rare opportunity to reconstruct Late Cretaceous life in remarkable detail: from giant predators to the smallest herbivorous inhabitants of the ancient continent.
