In Depth Shanxia is a genus of ankylosaur that lived in China during the Late Cretaceous. However not much fossil material is available and there is speculation that Shanxia may actually just be further remains of the genus Tianzhenosaurus. Further Reading - A new ankylosaurian dinosaur (Ornithischia: Ankylosauria) from the Upper Cretaceous of Shanxi Province, … Read more

In Depth Nanshiungosaurus was first described from partial remains mostly consisting of vertebrae in 1979. To begin with Nanshiungosaurus was thought to be a titanosaurian sauropod dinosaur, a bit later it was realised to be a therizinosaur. As a therizinosaur, Nanshiungosaurus was a theropod dinosaur that had adapted to a herbivorous diet instead of a … Read more
In Depth Ornithostoma was once considered to identical to Pteranodon, although modern thinking has it recognised as its own genus. Unfortunately Ornithostoma has suffered from the wastebasket effect with numerous poorly preserved remains being attributed to it. Although not much is known for certain, the toothless beak of Ornithostoma likely indicates a fish eating piscivorous … Read more
In Depth Kalaallitkigun is a genus of cynodont that lived in Greenland during the Triassic. At the time of its description Kalaallitkigun is known only from a partial lower jaw bone and a premolar and molar tooth. The teeth structure of the molar suggests that Kalaallitkigun was intermediate in its development lying somewhere between more … Read more

Further Reading - Barrosasaurus casamiquelai gen. et sp. nov., a new titanosaur (Dinosauria, Sauropoda) from the Anacleto Formation (Late Cretaceous: early Campanian) … Read more
In Depth Named in 2010, Kosmoceratops has quickly become a dinosaur fan favourite, thanks largely to the highly ornate form of the skull, which was also the inspiration for the genus name. To start, the frill section of the skull is twice as wide as it is long, which by physical proportions, means that it … Read more
In Depth The few scant fragmentary remains of Labocania make it very difficult to classify, but analysis of the post cranial elements suggest that it was a tyrannosaurid. What parts of the skull which are known are more robust however suggesting that Labocania had a differently shaped skull. It is easy to see why Labocania … Read more
