In Depth Compsosuchus is considered to be a very dubious genus of dinosaur, not only due to the incomplete remains but the fact that Charles Alfred Matley and Friedrich von Huene also named two other dinosaurs, Indosaurus and Indosuchus that combined with Compsosuchus may actually represent the same genus. Compsosuchus has been considered to be … Read more
In Depth Neimongosaurus is a genus of therizinosaur that lived in Asia during the late Cretaceous. Like other therizinosaurs, Neimongosaurus was descended from meat eating theropods, though the teeth in the lower jaw of Neimongosaurus which have coarse serrations which indicate that Neimongosaurus were plant eaters. Neimongosaurus has occasionally been classed as a member of … Read more
In Depth Mierasaurus is a genus of turiasaurian sauropod dinosaur that lived in Western North America during the early Cretaceous.

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
