Model of a Nasutoceratops skull

Nasutoceratops is a genus of ceratopsid dinosaur that lived in North America about 76.0 to 75.5 million years ago. The first known specimens were discovered in Utah in 2006. A subadult skull with a partial postcranial skeleton and rare skin impressions was made the holotype of the new genus and species Nasutoceratops titusi. It later featured in the Jurassic World films. The holotype skull of Nasutoceratops is approximately 1.5 m (4.9 ft) long, and its body length has been estimated at 4.5 m (14.8 ft) and its weight at 1.5 tonnes. Its brow horns are notable for pointing forward and being approximately 40 percent of total skull length. The functions of ceratopsian frills and horns have been debated: suggestions include signalling, combat, and species recognition; the forward oriented brow horns of Nasutoceratops may have enabled interlocking with opponents. During Nasutoceratops's lifetime its environment was dominated by wetlands supporting a diverse fauna, including other ceratopsians. (Full article...)
