Alcione is noted for having very short wings, something that could aid either flapping flight, or perhaps streamlining for use after entering water. This feature combined with the knowledge of the Alcione fossils coming from a … Read more

In Depth Nipponosaurus is classed as a lambeosaurine hadrosaurid because of the hollow head crest that rises up from the top of the snout, though the incomplete nature of the known remains makes it hard to establish fine details, and reconstructions are usually completed with comparisons to other better preserved genera. Also, because the fossils … Read more
In Depth Hulitherium is a genus of diprotodont wombat that lived in New guinea during the Pleistocene. Not much is known about Hulitherium, though the arm structure suggests that this genus was significantly more mobile than other diprotodonts.

In Depth A very small sauropod, Rayososaurus is considered to be very similar to another genus called Rebbachisaurus. Because Rayososaurus is from South America and Rebbachisaurus is from Africa, this has given rise to the notion that these two continents were joined for much longer than previously thought back in the Cretaceous.

In Depth Although not as famous as some sauropods like Apatosaurus and Diplodocus, Camarasaurus actually appears to have been the most common judging by the large numbers of remains. Some Camarasaurus specimens are actually almost complete and the genus also has one of the largest numbers of sauropod skulls attributed (for those who haven’t realised … Read more
In Depth An often included genus in dinosaur books, Arrhinoceratops is another example of a popular dinosaur known by very little fossil material. In this case Arrhinoceratops has been based upon the description of only a single partially preserved skull. Arrhinoceratops was named because William Parks thought that it lacked a nasal horn, and too … Read more

In Depth Parvicursor is a genus of alvarezsaur known to have lived in Mongolia during the Late Cretaceous. Like with some relatives, Parvicursor had hands reduced to a single stubby horn which was likely used to punch holes into termite mounds so that an individual Parvicursor could feed upon the termites within.

Discovery and Early Reconstruction of Iguanodon Iguanodon has a firm place within dinosaur history books, not just because of the large expanse of fossil material attributed to it, but because it was the second dinosaur to ever be identified and named. The first dinosaur was actually Megalosaurus which was named a year earlier, and back then the term … Read more
