In Depth Vayuraptor is a genus of coelurosaurian theropod dinosaur that lived in Thailand during the Early Cretaceous. With the first fossils of the genus being discovered in the Sao Khua Fomation, Vayuraptor possibly shared its habitat with the dinosaurs Phuwiangvenator (which was also named in the same paper as Vayuraptor), Kinnareemimus, Siamosaurus, Siamotyrannus and … Read more
In Depth Originally thought to be a species of Stegosaurus at the time of the first description in 1901, the partial post cranial remains were soon identified as being a distinct genus and renamed Hoplitosaurus in 1902. The species name which honours the famous American palaeontologist Othniel Charles Marsh, who actually named the genus Stegosaurus, … Read more
In Depth Mononykus has a close relationship with another genus of alvarezsaur named Shuvuuia in that many of the fossils once attributed to Mononykus olecranus were found to be of a distinct genus, and these were moved to their own genus named Shuvuuia. Hence many of the older reconstruction and information resources about Mononykus are … Read more
In Depth Nanosaurus used to be an uncertain genus of ornithopod dinosaur. In the past three species have been named for Nanosaurus, N. agilis, N. rex and N. Victor. The holotype of N. rex was used to create the genus Othnielia in 1977, while N. victor was later realised to be based upon crocodilian remains. … Read more
In Depth Geranosaurus was an ornithischian dinosaur that lived in South Africa during the early Jurassic. Because Geranosaurus is known from only very fragmentary fossil remains, many consider it a dubious genus as it will likely be very difficult to attribute further remains to the genus given there is so little to compare new discoveries … Read more
In Depth Since it was named in 1989, the dinosaur genus Bruhathkayosaurus has attained almost mythical status. The original description of the bones of this dinosaur were originally interpreted as belonging to a theropod dinosaur, though later study of the description has led readers to conclude that the remains were actually of a titanosaurid … Read more
In Depth Since the genus was named in 2003, there has been some speculation that Lamaceratops may in fact be based upon fossils referable to Bagaceratops. This is because there is very little difference between known fossils of Bagaceratops and the holotype fossils for Lamaceratops, though Lamaceratops may also represent a species of Bagaceratops not … Read more
In Depth The larger an animal becomes in life, the more likely it is that it will only be represented by a few bones, and this is because the body is usually scattered by the actions of scavengers as well as environmental factors such as floods and wind storms long before the body can be … Read more
In Depth Nemegtomaia was originally named Nemegtia in 2004, but it was soon realised that this name had already been used to name another animal. So in 2005 the describers renamed it Nemegtomaia to avoid confusion. Nemegtomaia is a genus of oviraptorid dinosaur that lived in what is now Mongolia during the late Cretaceous. At … Read more
In Depth Nankangia is a genus of oviraptorid dinosaur that lived in China during the late Cretaceous. Although only known from partial remains, Nankangia has been speculated to have been more inclined to eating plants because the jaw symphysis is not downturned. However the exact diet for Nankangia, like with many other oviraptorid genera is … Read more
