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
