In Depth Yehuecauhceratops is a genus of ceratopsian dinosaur that lived in North America during the late Cretaceous. The holotype individual of Yehuecauhceratops was discovered in the Aguja Formation of Mexico, and in life is thought to have been similar to nasutoceratopsine ceratopsian dinosaur genera such as Nasutoceratops and Avaceratops. Unfortunately because of the lack … Read more
In Depth Centrosaurus acquired its named from the numerous bony projections that run along the edges of its frill. Aside from these a large nasal horn extends upwards from the top of the snout, and a pair of small horns project from the eyebrow. Two more hornlets hook down from the top of the frill, … Read more
In Depth Officially named and described in 2015 from a single skull, Regaliceratops has already gone down as a particularly interesting ceratopsian dinosaur. The larger ceratopsians of the late cretaceous are usually divided into centrosaurines and chasmosauines, the former having large nasal horns and reduced frills, while the latter usually have reduced nasal horns and … Read more
In Depth Named in 2010, Kosmoceratops has quickly become a dinosaur fan favourite, thanks largely to the highly ornate form of the skull, which was also the inspiration for the genus name. To start, the frill section of the skull is twice as wide as it is long, which by physical proportions, means that it … Read more
In Depth Brachyceratops is regarded as a highly dubious genus of ceratopsian dinosaur that may represent the juvenile form of another already named genus, and indeed one specimen of Brachyceratops (USNM 14765, a sub adult referred to the original five juveniles) has already been moved to the Rubeosaurus genus. This would normally raise speculation that … Read more
In Depth Torosaurus was first named upon the description of two partial skulls by Othniel Charles Marsh all the way back in 1891, two years after he had named the much more famous Triceratops. The most common mistake regarding the name Torosaurus is the meaning, with many people misquoting it as meaning ‘bull lizard’ after … Read more
In Depth Nasutoceratops was the second genus of centrosaurine ceratopsian dinosaur to be discovered in the south west of the USA, the first genus being Diabloceratops that was named three years earlier. Back in the Cretaceous the South-west of what is now the USA was the southern portion of Laramidia, an island landmass extending from … Read more
In Depth Navajoceratops is a genus of ceratopsian dinosaur that lived in North America during the late Cretaceous. At the time of the description Navajoceratops is known only from a partial skull bones that a reveal a little of the shape of the neck frill. These suggest that Navajoceratops was a chasmosaurine ceratopsian dinosaur. Further … Read more
In Depth The fact that Albertaceratops has large and well developed brow horns on what is in essence a centrosaurine skull has led to the thinking that Albertaceratops is a basal centrosaurine ceratopsian. Later members of the group would develop considerably reduced brow horns. Albertaceratops had no nasal horn but instead had a bony growth … Read more
In Depth With holotype fossils initially described as specimens of Rubeosaurus, Stellasaurus is a genus of centrosaurine ceratopsian dinosaur that lived in North America during the late Cretaceous. Although little fossil material exists of Stellasaurus at the time of writing, the dinosaur has been reconstructing as having two large upwards pointing spikes rising from the … Read more
