In Depth Hypsilophodon is one of the more famous dinosaurs that have been discovered in the Isle of Wight, however its discovery was delayed by the fact that for the first twenty years of the first fossils discovery, Hypsilophodon was actually believed to be a juvenile Iguanodon. This is of course in reference to … Read more
In Depth Kukufeldia is a genus of ornithopod dinosaur that is known only from a partial jawbone. Most researchers have considered the genus to be a nomen dubium while others have proposed a synonymy with Barilium.

In Depth Unfortunately like with so many other Australian dinosaurs, Atlascopcosaurus is based upon the description of very incomplete remains, in this case part of a jaw. This jaw was been compared to other dinosaur types which has yielded the conclusion that Atlascopcosaurus was probably a member of the Euornithopoda. Also a very rough estimate … Read more
In Depth At around three meters long, Secernosaurus was very small for a hadrosaur, though its claim to fame is not size, but the fact that it was the first hadrosaur known to come from South America. In addition Secernosaurus seems to represent a saurolophine hadrosaurid similar to Kritosaurus, and saurolophines are best documented in … Read more
In Depth First named as a species of Hadrosaurus by Othniel Charles Marsh in 1872, Marsh later renamed this species as a distinct genus, Claosaurus in 1890. A second species, C. affinis, is now considered to be highly dubious, not only upon the grounds that it was based upon very fragmentary toe bones, but that … Read more

In Depth Once again the term ‘wastebasket taxon’ looms like a spectre over another dinosaur. Many of the fossils that were once attributed to Camptosaurus have since been found to represent other dinosaurs, and this is especially true for the European species that were once assigned to Camptosaurus. Despite this reduction in species and geographic … Read more
In Depth Notohypsilophodon is a genus of small ornithopod dinosaur that lived in South America during the late Cretaceous. Notohypsilophodon is so named based upon a superficial similarity to the genus Hypsilophodon while also recognising the more southern occurrence of this individual. Notohypsilophodon is so far only known from the partial remains of a juvenile, … Read more
In Depth Lapampasaurus is a late Cretaceous era genus of hadrosaur. Although only named from partial remains, the discovery is of yet another hadrosaur from South America. The continent of South America has long been assumed to have been isolated from North America during the Cretaceous, but the presence of hadrosaur genera such as Lapampasaurus, … Read more
