In Depth Deltadromeus was a mid-sized theropod that lived in North Africa, but while the time period it is known from places it in the late (or alternatively upper) Cretaceous, it actually roughly lived during the middle of this period. The skull of this dinosaur is so far unknown but the recovered post cranial remains … Read more

In Depth The Carbonemys holotype remains were first discovered in a coal mine, and since coal is essentially fossilised carbon, the name Carbonemys was chosen for the genus. The form of the shell is very interesting as it indicates that Carbonemys would have been a member of the Pleurodira, a group better known as the … Read more
In Depth Othnielosaurus is a genus of small ornithopod dinosaur that seems to have been widespread across Central North America during the late Jurassic. Othnielosaurus would have been a bipedal dinosaur relying more upon speed and agility to stay out of the mouths of predatory dinosaurs. Othnielosaurus like other ornithopods were herbivorous dinosaurs that would … Read more
In Depth The holotype specimen of Callovosaurus, an almost complete femur, was first described as a species of Camptosaurus all the way back in 1889 by Richard Lydekker. By 1909 doubts were already being cast as to whether or not this bone actually came from an iguanodontid dinosaur. In 1980 Peter M. Galton took this … Read more
In Depth Even though the name Eocarcharia means ‘dawn shark’, it was actually a theropod dinosaur. This name came about from the serrated slicing teeth that are thought to have sliced through flesh as easily as a shark. The dawn part is a reference to its early appearance to some other related genera. Although only … Read more

In Depth Selmasaurus is unusual amongst mosasaurs because it has an akinetic skull, which means that its jaws were incapable of widening to swallow larger prey. This strongly suggests that Selmasaurus restricted itself to small prey species that were easily swallowed. This would infer behaviour similar to other plioplatecarpine mosasaurs such as Platecarpus and Plioplatecarpus … Read more
