In Depth In terms of paleontological study, Hadrosaurus was a genus of firsts. One of the things that the genus is famous for is that it was the first dinosaur to have a skeleton mounted for public display. Earlier reconstructions such as the now outdated dinosaurs of Crystal Park in England are brick and concrete … Read more
In Depth Hadrosaurs have a long association with North America, but they are known from other areas like Asia where they are usually represented by incomplete remains. Olorotitan however was almost complete and became widespread through palaeontology circles as the most complete lambeosaurine hadrosaurid outside of North America. With eighteen vertebrae Olorotitan is also remarkable … Read more
In Depth In the closing years of the twentieth century a bone bed containing the remains of at least twenty-seven juvenile dinosaurs was excavated in South Africa. The 2022 study describing the genus (Forster et al.) considers these juveniles to represent everything from hatchlings to subadults, Possibly located at a nesting site. The 2022 description … Read more
In Depth Orodromeus was a small ornithopod dinosaur of the late Cretaceous that had boss-like growths on the jugals (cheek bones). Orodromeus has been considered to be similar to another small ornithopod named Oryctodromeus, which itself is considered to have been a burrowing dinosaur. It is still not known for certain if Orodromeus burrowed and … Read more

In Depth Cionodon is a dubious genus of hadrosaur that is based only upon very partial and fragmentary remains. So far two species of Cionodon continue to exist, but because of the poor quality of their fossils, it is next to impossible to assigned further remains to them, or even to identify them as synonymous … Read more
In Depth Barsboldia is so far only known from vertebrae and some fragmentary remains of other parts of the post cranial skeleton. At the time of writing no skull is known for the genus, yet the original describers still chose to class Barsboldia as a lambeosaurine hadrosaurid dinosaur. Later studies however have cast doubts about … Read more
In Depth Originally named as a species of Iguanodon, Dakotadon is so far only known from a partial skull. Like other ornithopods, Dakotadon would have fed upon plants growing at varying heights, adjusting its stance and posture to reach.

In Depth Penelopognathus is a genus of hadrosauroid dinosaur that lived in Mongolia during the early Cretaceous. Unfortunately, because only a partial jaw of this dinosaur has been recovered, not much is known about Penelopognathus.
