In Depth Originally named as a species of Mosasaurus, Goronyosaurus was a medium sized mosasaur that lived in the waters of Africa. So far fossils of Goronyosaurus have been found in Niger and Nigeria. The key thing here is that Niger is a land locked country, so this may actually be an indicator that Goronyosaurus … Read more

In Depth The modern history of the sauropod dinosaur Barosaurus begins in 1889 with the discovery of the first Barosaurus fossils by a Ms E. R. Ellerman in South Dakota. Six caudal (tail) vertebrae were subsequently recovered by the famous American palaeontologist Othniel Charles Marsh later that year, though other remains were left at the … Read more
In Depth Eosipterus has enjoyed a variable position amongst the pterosaurs first being thought to be similar to Pterodactylus, then thought to have been a member of the filter feeding ctenochasmid pterosaurs, perhaps like Gnathosaurus, to ultimately being declared to be similar to Germanodactylus. The overall physiology of Eosipterus is quite robust, especially the wings. … Read more
In Depth Sachicasaurus is a genus of large brachauchenine pliosaur that lived in waters around South America during the early Cretaceous. Like other similar pliosaurs, Sachicasaurus is noted for having shorter jaws, and hence reduced number of teeth. Further Reading - A new large pliosaurid from the Barremian (Lower Cretaceous) of S�chica, Boyac�, Colombia. Earth … Read more
In Depth Lophorhothon was first discovered in the US state of Alabama in the Mooreville Chalk Formation. During the Cretaceous, this area was known as a region of Appalachia (the eastern landmass of North America at the time separated from Laramidia in the West), and what is significant about this is that when Lophorhothon was … Read more

Like relatives, Coahomasuchus had plate like osteoderms that ran down the length of the back and under the throat. With a length of about one and a half meters, Coahomasuchus is one of the smaller aetosaurs. Further Reading … Read more
In Depth Fodonyx is a genus of rynchosaur that lived in England during the early part of the Mid Triassic. The genus was born out of the decision to move a species of the Rhynchosaurus genus on the basis of differences from the type species that by todays taxonomic standards would warrant a new … Read more
In Depth Gobisaurus is very similar to another earlier named ankylosaur called Shamosaurus, yet there are enough differences in the skull features to be certain that these are separate genera, but ones that seem to be closely related. New analysis of the Ulansuhai Formation has also indicated that Gobisaurus may have lived around the Turonian … Read more
In Depth First described in 1842, Rhynchosaurus was the first ever rhynchosaur to be named, which is exactly why rhynchosaurs are called rhynchosaurs. Rhynchosaurus had a squat low slung body that was supported by all four legs. Rhynchosaurus is famous for the enlarged shearing teeth at the front of the mouth which would have easily … Read more
