In Depth Although only known from partial remains, Patagonykus is confirmed to have been an alvarezsaur, small bipedal dinosaurs that are thought to have specialised in hunting insects. Dinosaurs like Patagonykus were once thought to have been restricted to the lower stages of the upper Cretaceous, however the discovery of Bonapartenykus in 2012 has revealed … Read more

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 Alocodon is considered to be highly dubious genus of dinosaur since its description is based upon only teeth. In the past the teeth of Alocodon have been interpreted as being both a hypsilophodontid and a thyreophoran, two very different kinds of ornithischian dinosaurs. This is why the genus is considered a nomen dubium, … Read more
Lambeosaurus the dinosaur Lambeosaurus is one of the hadrosaurs that is frequently depicted in dinosaur books and toys, and study of this genus is required learning for anyone who wishes to know more about the hadrosaurs in general. Lambeosaurus is best known from Canada and upper Montana USA, although other attributed fossils in the past … 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 Pedopenna is a genus of small maniraptoran dinosaur that lived in China during the end of the Mid Jurassic. Pedopenna is classed as a member of the Deinonychosauria, the group that incorporates later dromaeosaurs and troodonts, as well as the ancestors of birds. Pedopenna already displays some features that would be common in … Read more
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
