In Depth The material of Vagaceratops was first removed from its block in 2001 when palaontologists identified it as a species of Chasmosaurus, C. irvinensis. Further study in 2010 however revealed it to be different enough to give it its own genus. Normal procedure for this occurrence is to take the specific species name of … Read more
In Depth Out of all the hadrosaurs (popularly known as duckbilled dinosaurs) Aralosaurus is noted for having extremely little in the way of fossil material attributed to it; a piece of the skull. This piece however does suggest the presence of an arched nasal area similar to that seen in other genera such as Gryposaurus … Read more

In Depth Changmiania is a genus of small ornithopod dinosaur that lived in Asia during the early Cretaceous. The genus was described in 2020 upon the description of two individuals whose level of preservation can only be described as exceptional. The describers speculated that these individuals may have been buried alive in their own burrows, … Read more
In Depth Known mostly from skulls, Prenocephale seems to have been a fairly large pachycephalosaur that lived in what is now Mongolia. The snout of Prenocephale is narrower than that of many other pachycephalosaur genera, suggesting that it was more of a selective browser. While Prenocephale is considered to be a valid genus, two others … Read more
In Depth Invictarx is a genus of nodosaurid dinosaur that lived in North America during the Late Cretaceous. Fossils so far associated with Invictarx are partial bones and osteoderms (bony plates of the skin that would have served as armour), so details as to a precise size are elusive. But the size of these remains … Read more
In Depth Alocodon is considered to be highly dubious genus of dinosaur since its description is based upon only teeth. In the past the teeth of Alocodon have been interpreted as being both a hypsilophodontid and a thyreophoran, two very different kinds of ornithischian dinosaurs. This is why the genus is considered a nomen dubium, … Read more
