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 Luanchuanraptor can go down in palaeontological history as the first Asian dromaeosaurid found outside of the Gobi Desert. Beyond this however the partial remains of the holotype make it hard to establish details about this genus. Luanchuanraptor was a dromaeosaurid meaning that it was a relatively small theropod dinosaur similar to others such … Read more
In Depth Despite its diminutive size Compsognathus is one of the dinosaurs that are best known to science. Not only was the skeleton well persevered but the remains of its last meal, a small lizard named Bavarisaurus were also found inside the specimen proving without doubt that Compsognathus was a carnivore. At the time of … Read more
In Depth Supersaurus is a relative of the ever famous Diplodocus and Apatosaurus (formerly known as Brontosaurus), as these three genera are all described as diplodocid sauropods. Diplodocids are members of the Diplodocidae and are noted for their long necks and tails, the latter of which are very thin and whip-like. Diplodocids can be further … Read more
In Depth Although only known from partial remains, Patagonykus is confirmed to have been an alvarezsaur, small bipedal dinosaurs that are thought to have specialised in hunting insects. Dinosaurs like Patagonykus were once thought to have been restricted to the lower stages of the upper Cretaceous, however the discovery of Bonapartenykus in 2012 has revealed … Read more

In Depth Fossils of Lourinhasaurus were first described in 1957, but were initially thought to be a species of Apatosaurus. A second individual described in 1983 led to the notion that the fossils were not of a new species but an entirely new genus. Fossils of Lourinhasaurus have also previously been labelled as species of … 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
