In Depth The name Koparion is based upon the comparison of the serrated teeth (currently the only known parts of this dinosaur) to ancient versions of scalpels. Despite the lack of overall remains, Koparion is widely regarded as being a troodontid and if this is correct, it would be one of the if not the … Read more
In Depth Although Sinotyrannus has been described from very incomplete material, the palaeontologists who described this dinosaur have managed to conclude that it is a close relative of the primitive tyrannosaurs. Additionally they have also compared the remains to similar dinosaurs and come up with a rough length estimate of up to ten meters long … Read more

In Depth The first genus of theropod dinosaur to ever be named from India’s Lameta Formation, Orthogoniosaurus has often been considered to be a senior synonym for other theropod genera that were later discovered. However the holotype of Orthogoniosaurus is only a tooth, and because of this no other fossil remains have been attributed to … Read more
In Depth Archaeornithoides has proven to be a problematic genus since it has been very difficult to ascertain exactly what it was. Only known from partial paired maxilla and dentaries, Archaeornithoides was first considered to be a primitive bird because of what were considered distinct bird-like features. Later discoveries however proved that these distinct bird … Read more
In Depth Originally named as Elaphrosaurus gautieri in 1960, a 2004 analysis of the remains by P. C. Sereno, J. A. Wilson and J. L. Conrad concluded that they belonged to a different genus of dinosaur. Hence forth this fossil material now goes by the name of Spinostropheus based upon the shape of the vertebrae, … Read more
In Depth Magyarosaurus is considered the smallest titanosaur, and is regarded as a fine example of insular dwarfism. This is where animals that live in an area of limited size, such as an island, grow smaller so as not to use up the available food supply. Although some have made the suggestion that Magyarosaurus specimens … Read more

In Depth Although based only upon the description of the braincase, it has been enough to not only identify Nebulasaurus as a new eusauropod dinosaur, but also further hints that during the middle Jurassic Asia had a very diverse range of sauropod dinosaurs. By the late Jurassic this diverse range seems to have thinned out … Read more
In Depth Originally attributed as juvenile Saurornithoides mongoliensis, the partial left hind limb of this troodontid was firmly established as being of a different genus thanks to an osteohistological analysis of the bone. This revealed that the fossils were closer to Linhevenator tani, yet the team studying the remains concluded that while similar, the remains … Read more
