In Depth Noasaurus is the type genus of the noasauridae, a side group of theropod dinosaurs that are thought to have had the same immediate origins as the abelisaurids (such as Abelisaurus and Aucasaurus). Noasaurus however is only known by very partial remains which makes it difficult to ascertain specific details about this dinosaur. At … Read more
In Depth Ubirajara is a genus of compsognathid dinosaur that lived in South America during the early Cretaceous. At the time of its description Ubirajara is unique amongst the compsognathids due to the elaborate feather covering. This is mainly from a bushy mane of hair like proto-feathers that measured up to 11 centimetres long over … 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 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
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
In Depth Dating from the Bathonian period, Kileskus is even older than Guanlong making it a contender for one of the earliest tyrannosaurs. The partial skull remains have revealed the presence of a crest that rose up from the snout. Beyond this the only thing that can be said about Kileskus is that it appears … Read more

Owen however did not realise that he was dealing with a dinosaur, he actually thought that he was dealing with a giant marine crocodile. The first sauropod to actually be identified as a dinosaur was … Read more
In Depth Pyroraptor acquired its name from the circumstances of its discovery. In 1992 the partially preserved remains of this dinosaur where discovered after a forest fire had swept through the area. Despite the very incomplete remains it has been possible to identify Pyroraptor as a distinct genus from the unique form of the sickle-shaped … Read more
In Depth The holotype fossils of Duriatitan have were previously considered to be species of the genera Ornithopsis and Pelorosaurus, finally settling in Cetiosaurus, by John Hulke all the way back in 1874, before finally being named as a distinct genus in a 2010 re-description. Duriatitan however still suffers from a distinct lack of fossils, … Read more
In Depth Way back during the 1890s, a fossil collector named Phillip James Rufford discovered a partial dorsal vertebrae near Hastings in East Sussex, England. Eventually catalogued as BMNH R2095, the vertebrae was first thought to belong the genus Cetiosaurus by Richard Lydekker, before eventually becoming Pelorosaurus conybeari. That was about it for well over … Read more
