In Depth Kaijiangosaurus is only known from very fragmentary remains, so it is difficult to establish exactly where it belongs in relation with other dinosaurs. Further remains have been attributed to the genus but are currently undescribed, but some palaeontologists have leaned towards a classification within the Megalosauridae (the theropod dinosaur group typified by Megalosaurus). … Read more
In Depth Koreaceratops made headlines in 2011 for two reasons, the first being that this was the first ceratopsian dinosaur to be discovered in South Korea. The second is the theory that Koreaceratops may have been semi aquatic. The latter is idea is based upon the observation of the tall neural spines of the recovered … Read more
In Depth Sarahsaurus is currently one of the few known basal sauropodomorphs from North America, with other genera including Anchisaurus and Seitaad. The sauropodomorphs were the forerunners to the later giant sauropods that would become dominant as the Jurassic era progressed on. As a basal sauropodomorph, Sarahsaurus is thought to have been a plant eating … Read more
In Depth Halszkaraptor is without doubt one of the most interesting dromaeosaurid dinosaurs ever discovered. Although a dromaeosaurid dinosaur, Halszkaraptor seems to have lived more like a modern day semi aquatic bird. Halszkaraptor could still walk about on land, the rear legs were easily strong enough for this. But the tail was not stiffened like … Read more
In Depth Fossils of Cruxicheiros were first discovered in 1960 when they were discovered in the Cross Hand Quarry of Warwickshire, which as you have no doubt already realised is the inspiration for the name Cruxicheiros which means ‘Cross Hand’. At the time the fossils were just lumped in with Megalosaurus, which has for a … Read more
In Depth Named after the Mapuche word for the Colorado River (Muyelen) Muyelensaurus was a genus of titanosaur that lived in Argentina during the Coniacian of the Cretaceous. Muyelensaurus is notable by being a particularly gracile genus of titanosaur. Further Reading A new titanosaur sauropod from the Late Cretaceous of Neuqu�n, Patagonia, Argentina. - Arquivos … Read more
In Depth First named as a species of Stegoceras, Colepiocephale appears to have been a small genus of pachycephalosaur dinosaur that lived in Canada during the late Cretaceous. Unfortunately Colepiocephale is still only known from a partial skull dome, so the exact size of the living dinosaur is still unknown, but estimated to be around … Read more
In Depth The description of Loricosaurus was first based upon the discovery of osteoderm armour that was initially perceived to have come from an ankylosaur. Later it was realised that these osteoderms actually came from a titanosaur, however, by themselves they are not very diagnostic of a distinct genus, which is why Loricosaurus is widely … Read more
In Depth By the start of the Late Cretaceous the central portion of North America had been submerged by a shallow sea. This created two landmasses out of the North American continent, Laramidia in the west and Appalachia in the east. Most Cretaceous era dinosaurs from North America have been found in what was once … Read more
In Depth At eight meters long Rocasaurus was actually quite small for a sauropod, though it still would have been one of the larger dinosaurs on the landscapes of late Cretaceous Argentina. However if the holotype is correctly interpreted as that of a juvenile, then adults of the genus would have certainly grown larger. Another … Read more
