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 Aorun was a genus of coelurosaurian theropod that lived in China during the late Jurassic period. The holotype remains of are those of an individual which means that adults would have been a bit bigger and a little different, though the holotype remains of this genus are still enough to identify a new … Read more
In Depth In terms of size, Anchiornis was a very small dinosaur indeed, though this is not the claim to fame for the genus. Anchiornis is known to have been feathered and one specimen is so well preserved that palaeontologists have been able to determine what colour and pattern these feathers were in life. Anchiornis … Read more
In Depth Adasaurus is a genus of dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous. Like with its relatives, Adasaurus was a hunter of other animals, quite possibly including other dinosaurs. The primary killing weapons for Adasaurus would have been the two enlarged sickle claws on its feet, which may have been used … 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 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
