In Depth Fossils of Lourinhasaurus were first described in 1957, but were initially thought to be a species of Apatosaurus. A second individual described in 1983 led to the notion that the fossils were not of a new species but an entirely new genus. Fossils of Lourinhasaurus have also previously been labelled as species of … Read more
In Depth Although two species have been named for this genus of sauropod dinosaur, they have both been established upon the description of teeth. For this reason Asiatosaurus is usually treated as a highly dubious genus of sauropod. Further Reading - Sauropoda and Theropoda from the Lower Cretaceous of Mongolia.

In Depth Described from a partial skeleton, Seitaad is one of the few North American sauropodomorphs currently known. It is widely believed that the individual that is now the Seitaad holotype was buried in a landslide from a collapsing sand dune, and hence this is the inspiration for the genus name.

In Depth Daliansaurus is a genus of small troodontid dinosaur that lived in China during the early Cretaceous. Many trrodontid dinosaurs are known to have been living in the same approximate time and location as Daliansaurus, but the describing paleontologists identified several features that differentiate this genus from others. Some of the clearer differences are … Read more
In Depth Named in 1890 from a partial hand and foot, Ornithomimus became the first known ornithomimid, which is why it is considered the type genus of the Ornithomimidae. The ornithomimds (also sometimes called ‘ostrich dinosaurs’) were small dinosaurs that usually ranged between three and four meters long, although some were slightly larger. During the … Read more
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
