In Depth Unfortunately like with so many other Australian dinosaurs, Atlascopcosaurus is based upon the description of very incomplete remains, in this case part of a jaw. This jaw was been compared to other dinosaur types which has yielded the conclusion that Atlascopcosaurus was probably a member of the Euornithopoda. Also a very rough estimate … Read more
In Depth Wuerhosaurus is currently the latest surviving known member of the stegosaur group. In being so, the temporal range of these kinds of dinosaurs has been significantly extended up to the middle Cretaceous, forty-five million years after their Jurassic heyday. Unfortunately Wuerhosaurus is only represented by partial remains, making accurate reconstruction of this stegosaurid … Read more
In Depth The problem with most dinosaur remains from the Cambridge Greensand is that they are incomplete representations of a living animal, and collections of fossils can often be the mixed up remains of more than one genus. In the past the genus of Anoplosaurus has been accused of being partially composed of ornithopod dinosaur … Read more
In Depth At around three meters long, Secernosaurus was very small for a hadrosaur, though its claim to fame is not size, but the fact that it was the first hadrosaur known to come from South America. In addition Secernosaurus seems to represent a saurolophine hadrosaurid similar to Kritosaurus, and saurolophines are best documented in … 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 First named as a species of Hadrosaurus by Othniel Charles Marsh in 1872, Marsh later renamed this species as a distinct genus, Claosaurus in 1890. A second species, C. affinis, is now considered to be highly dubious, not only upon the grounds that it was based upon very fragmentary toe bones, but that … Read more

In Depth Liaoceratops was a fairly small neoceratopsian dinosaur that is nonetheless a good example of the ancestors of the later and larger ceratopsian dinosaurs such as Triceratops and Styracosaurus that lived during the late Cretaceous. Liaoceratops had the beginnings of a neck frill, though nothing like the same scale as later descendants, and no … 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
In Depth Texasetes was the first armoured nodosaurid dinosaur to be named from the Paw Paw Formation of Texas. However a year later a second genus of nodosaur called Pawpawsaurus was named, though only represented by a skull. There has now been suggestions that these two are the same genus, and if proven true, then … Read more
