In Depth The holotype individual of Microvenator was first discovered by the famed American palaeontologist Barnum Brown in 1933. Brown noted that the holotype individual had what he thought was a disproportionately large head, and so came up with the name Megadontosaurus. A reference to the large head, but also the teeth found near it. … Read more
In Depth When first described in 1988 by Zhang Yihun this sauropod dinosaur genus was named as Protognathus. However it was soon realised that the name Protognathus had already been used to name a genus of beetle, so the dinosaur was renamed buy George Olshevsky to become Protognathosaurus in order to make it distinct from … Read more
In Depth Named after Erlik, the demon king in Mongolian mythology, Erlikosaurus was a ground breaking discovery as it was the first therizinosaurid skull known to science. Despite the overall lack of other skeletal material, this skull made Erlikosaurus a model for other therizinosaurids, which at the time were only known from their post cranial … Read more
In Depth Originally named Coloradia, it was later discovered that the genus name had already been assigned to a type of moth, hence the revision and change to Coloradisaurus in 1983. Identified as a massospondylid sauropodomorph, Coloradisaurus has been considered as a synonym to the genus Mussaurus. However, Mussaurus has been established only upon hatchlings, … Read more
In Depth Living in India during the early Jurassic, the dinosaur Lamplughsaura has been the source of some head scratching amongst palaeontologists. The two main options at the moment are that either Lamplughsaura represents a very advanced sauropodomorph, or a primitive sauropod dinosaur. What can be established however is that Lamplughsaura does represent a transitional … 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 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 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 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
