In Depth Supersaurus is a relative of the ever famous Diplodocus and Apatosaurus (formerly known as Brontosaurus), as these three genera are all described as diplodocid sauropods. Diplodocids are members of the Diplodocidae and are noted for their long necks and tails, the latter of which are very thin and whip-like. Diplodocids can be further … Read more

Pukyongosaurus: Research Database Reptilia (Sauropoda) · Late Cretaceous (~80 MYA) · Asia — South Korea Research Note: Pukyongosaurus was a sauropod dinosaur from the Late Cretaceous of South Korea — significant for representing Asian titanosaur diversity and providing important data on sauropod evolution in East Asia during the Cretaceous. Research Finding Status Grade … Read more
Lourinhasaurus: Research Database Diplodocidae (Sauropoda) · Late Jurassic (~160–145 MYA) · Europe — Portugal (Lourinhã Formation) Research Note: Lourinhasaurus was a diplodocid sauropod from the Late Jurassic Lourinhã Formation of Portugal, one of the few named dinosaur species from the Iberian Peninsula. As a member of the Diplodocidae — a group of long-necked sauropods … 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: Research Database Lambeosaurinae (Hadrosauridae) · Late Cretaceous (~76–73 MYA) · North America — Canada, Alberta; USA, Montana (Dinosaur Park, Two Medicine Formations) Research Note: Lambeosaurus was a lambeosaurine hadrosaurid from the Late Cretaceous of western North America, famous for its elaborate cranial crest — a hollow, helmet-like structure that may have been used … 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.

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.
