In Depth Although known from very well preserved remains, there is still quite a bit of mystery surrounding Limusaurus. Study of the bones has revealed that it is a member of the Ceratosauria (the first one known from Asia), a group of theropods defined by the type genus Ceratosaurus. However the one specimen where the … Read more
In Depth The holotype fossils of Kayentavenator were originally described as Syntarsus kayentakatae until later study declared them to represent a distinct genus of theropods (additionally Syntarsus has now been declared a synonym of Megapnosaurus). Not a lot can be said for Kayentavenator because the skeletal remains are incomplete and of a juvenile dinosaur; combined … Read more
In Depth Although so far only known from partial remains, Qiupalong has been identified as a distinct ornithomimid genus on the basis of differences in the tibia from other known genera of this group. Further analysis has led the team that described Qiupalong to consider it to be similar to Struthiomimus altus and Ornithomimus edmontonicus, … Read more
In Depth Riojasaurus was and still often is credited as being related to Melanorosaurus, though detailed study of the two genera does turn up some key differences. These two genera are both significant in the development of the sauropodomorphs into the large sauropods common by the late Jurassic in that they are both large and … 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. This assessment was seconded in 1932 when Friedrich von Huene classified Gryponyx in with the Carnosauria. By 1976 Gryponyx was realised to actually be a sauropodomorph dinosaur (the group ancestral to … Read more
In Depth Since the naming of the genus in 1893, Microcoelus has become something of a dubious genus of titanosaur. This is because at the time if writing only a single dorsal (back) vertebra is known. A humerus (upper arm bone) that was once assigned to the genus has now been moved to the genus … Read more
