In Depth To begin with, one of the most interesting facts about Revueltosaurus is that the genus was first believed to have represented a very primitive orithischian (bird-hipped) dinosaur. This is because when Revueltosaurus was first discovered the genus was only described by teeth, and these were very similar to the ornithiscian dinosaurs of the … Read more

In Depth Most nimravids were relatively small cat-like mammals that ranged between one and two metres in length, but Quercylurus was a giant when compared to these, something which leads to the popular comparison of Quercylurus being the size of a brown bear. This size would make Quercylurus comparable to some of the larger creodont … Read more

In Depth Daanosaurus is based upon the description of a partial skeleton with some skull bones that have been confirmed to be those of a juvenile. This has been confirmed by the complete lack of fusion in the holotypes vertebrae. Daanosaurus has been identified as a member of the Brachiosauridae sauropods, and may be a … Read more
In Depth Wintonotitan and Diamantinasaurus were the first major sauropod discoveries in Australia since the discovery of Austrosaurus seventy-five years earlier. In fact when the first fossils of Wintonotitan where recovered they were actually taken to be further remains of Austrosaurus. Although Wintonotitan and Diamantinasaurus are of comparable size and from the same area, Wintonotitan … Read more

In Depth Gryponyx was first named by Robert Broom in 1911who when he described this dinosaur thought that he was naming a theropod dinosaur.

By 1976 Gryponyx was realised to actually be a sauropodomorph dinosaur (the group ancestral to … Read more
