Nanshiungosaurus
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
Ornithostoma
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
Kalaallitkigun
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
Barrosasaurus
In Depth Barrosasaurus is a genus of sauropod dinosaur that lived in South America during the late Cretaceous. At the time of its description, the genus is only represented by three dorsal vertebrae. Further Reading - Barrosasaurus casamiquelai gen. et sp. nov., a new titanosaur (Dinosauria, Sauropoda) from the Anacleto Formation (Late Cretaceous: early Campanian) … Read more
Kosmoceratops
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
Labocania
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
Rhabdodon
In Depth Rhabdodon is for lack of a better term a puzzle. Although usually described as an iguanodont, Rhabdodon has also been considered as a hypsilophodont, and on top of this it has also been described as a ‘missing link’ between these two groups of dinosaurs. To further the confusion however, Rhabdodon lived in the … Read more
Protostega
In Depth Protostega is one of the largest turtles to ever swim in the ocean and so far is only eclipsed by Archelon in terms of overall size. Like with Archelon, Protostega is thought to have had a ‘soft’ shell similar to the modern leatherback turtle (Dermochelys coriacea). Also like with Archelon, Protostega is thought … Read more
Sinotherium
In Depth Sinotherium is a genus of extinct rhinoceros that seems to have been broadly spread across Eurasia between what is now Russia and northern China. The Sinotherium genus is has been believed to have evolved from the earlier Iranotherium. In turn Sinotherium is believed to have given rise to the much better known Elasmotherium. … Read more
