Hadrosauroids were the descendants of the iguanodonts that were common in the late Jurassic/earliest Cretaceous, and the precursors of the hadrosaurids that were common during the final ten-fifteen million years of the Cretaceous.

In Depth Emausaurus is a primitive genus of thyreophoran dinosaur that lived in Europe during the early Jurassic. Emausaurus was first described by a description of the skull, though osteoderms (bony plates that were in the skin) are also known. Emausaurus seems to have been a small to mid-sized dinosaur that would have relied upon … Read more
In Depth Eousdryosaurus is a genus of small ornithopod dinosaur that lived in Portugal during the late Jurassic. The name Eousdryosaurus means ‘eastern Dryosaurus’, a reference to how Eousdryosaurus is similar to the genus Dryosaurus, but globally lived further to the east, Eousdryosaurus in Portugal, and Dryosaurus in North America.

In Depth Crichtonsaurus seems to have been a fairly small genus of ankylosaur that lived in China during the earlier stages of the Late Cretaceous period. As an ankylosaur Crichtonsaurus would have been a squat quadrupedal dinosaur that browsed upon low growing plants. At the time of writing two species of Crichtonsaurus have been identified … Read more
In Depth Fossils sitting in a museum and sometimes thought to belong to one kind of ceratopsian dinosaur are sometimes found to actually represent another upon later examination. This is how others such as Mojoceratops and Spinops were discovered, and is also how Ojoceratops was discovered. Ojoceratops was classed as Torosaurus, but is thought to … Read more
In Depth Originally named as a species of Camptosaurus, Uteodon was a fairly primitive iguanodont dinosaur that lived in what is now Utah during the late Jurassic. As an iguanodont, Uteodon would have been a primarily quadrupedal plant eater, though it may have still reared up on its hind legs to reach higher vegetation. Possible … Read more
In Depth Kelumapusaura is a genus of hadrosaurid dinosaur that lived in South America during the late Cretaceous. The establishment of Kelumapusaura was born out of the discovery of a bone bed of at least several individuals. Further reading - A new hadrosaurid (Dinosauria: Ornithischia) from the Late Cretaceous of northern Patagonia and the radiation … Read more
In Depth The description of the ceratopsian dinosaur Udanoceratops is based upon the discovery of an almost complete sixty centimetre long skull. This in turn led to size estimates for the missing body leading all the way up to four meters long; however it would be interesting to see how Udanoceratops compares to other later … Read more
In Depth Spiclypeus is a genus of ceratopsian dinosaur that lived in North America during the late Cretaceous. Further Reading - Spiclypeus shipporum gen. et sp. nov., a boldly audacious new chasmosaurine ceratopsid (Dinosauria: Ornithischia) from the Judith River Formation (Upper Cretaceous: Campanian) of Montana, USA. - PLoS ONE 11(5). - J.

In Depth Sometimes dubbed the ‘Asian Iguanodon’, Probactrosaurus is no way near as well-known as its older and far more famous relative (which was actually the second dinosaur genus named, and the first one named that ate plants). At roughly five and a half meters in length Probactrosaurus was actually quite small when compared to … Read more
