In Depth Eromangasaurus was initially known as E. carinognathus, but this was seen as a synonym to the second species of Tuarangisaurus which was also named in 2005. The material became known as Tuarangisaurus australis until further study by Bernjamin P. Kear revealed several key differences. In 2007 Eromangasaurus was resurrected as a distinct genus … Read more
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 Originally thought to be a skull of a pliosaur, the Plesiosuchus holotype remains were originally credited as a species of Steneosaurus by John Hulke in 1870 . Steneosaurus is a genus of teleosaurid crocodile, a type believed to be common in coastal locations such as estuaries where they fed upon fish. Later study … 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 Unfortunately very little fossil material for this pterosaur exists, but the post cranial remains of Hatzegopteryx do bare striking similarities to Quetzalcoatlus, even to point that some consider Hatzegopteryx to be a possible synonym of Quetzalcoatlus. There still is one subtle area of known difference, and this is the way that the jaws … Read more
In Depth Stagonolepis had the typical aetosaur body form, quadrupedal, short legs and osteoderms than ran down the length of the body. This form could be described as crocodile-like, but caution should be exercised before assuming that Stagonolepis lived like a crocodile as well. Stagonolepis had neither piercing or slicing teeth, but peg-like teeth adapted … Read more
