In Depth Although very little fossil material has been found, Helioceratops has been identified as a basal (or primitive) form of ceratopsian dinosaur. This means that it is unlikely that Helioceratops sported the elaborate frill and horns of the larger quadrupedal ceratopsians that most people know. Although primitive, Helioceratops seems to have had a body … Read more
In Depth Lasasaurus was a genus of procolophonid parareptile (the type genus of the group being Procolophon) that live in Madagascar during the early Triassic. Further Reading - First procolophonid (Reptilia, Parareptilia) from the Lower Triassic of Madagascar - Comptes Rendus Palevol - J. Falconnet, M. Andriamihaja, �. L�ng & J. -S. B. Steyer - … Read more
In Depth Dilophosaurus is a very distinctive dinosaur that is instantly recognisable by the two crests that are on top of its neck. It must be remembered however that Dilophosaurus never had a neck frill or spat venom, as was depicted in the 1993 film Jurassic Park. Those were the creations of artistic licence, not … Read more
In Depth Like Polacanthus, Gastonia was a low browsing armoured dinosaur, but unlike Polacanthus however it is very well preserved. In fact Gastonia is the best preserved member of its group and this has allowed for what are considered more accurate reconstructions of other lesser known species. It’s quite possible that one of the main … Read more
In Depth Steneosaurus is a genus of teleosaurid crocodile that lived during the late Jurassic of Europe. As a genus Steneosaurus once had a great many species attributed to the genus, but over the years this was a result of what is known as the wastebasket taxon effect This is where a genus is based … Read more
In Depth The history of Piveteausaurus is one that is littered with comparisons to other theropod genera. The braincase that is the holotype fossil of Piveteausaurus was first described in 1923 by Jean Piveteau. Fossils of other dinosaurs had been discovered in the same region as this braincase all the way back to 1808 when … Read more
In Depth Nyctiphruretus is a contender for one of the coolest names of any prehistoric animal since the name translates to English as ‘guardian of the night’. Nyctiphruretus was an herbivorous procolophonomorph, that seems to have had a preference for plants that were either aquatic, or growing in wetlands. This is because all of the … Read more
In Depth Chaohusaurus is a genus of ichthyosauromorph marine reptile that lived in sea waters around Asia during the early/mid Triassic. Chaohusaurus had a similar body plan to other primitive ichthyosaurs being more lizard-like than fish-like as seen in later ichthyosaurs. Still, the limbs of Chaohusaurus were adapted to form paddles, and the rear half … Read more
In Depth Like so many early discovered dinosaurs Thecodontosaurus had more fossils assigned to it than it really warranted. This has led to a re-evaluation of the attributed material, and like so many other studies, has resulted in the reduction of total species to the point that only Thecodontosaurus antiquus is now universally recognised by … Read more
In Depth Berberosaurus will catch the eye of anyone interested in theropod dinosaurs because the genus may represent the oldest ceratosaur, though not everyone is in agreement. The original description of Berberosaurus came to the conclusion that Berberosaurus was an abelisauroid that was more advanced than genera such as Elaphrosaurus and Spinostropheus, though more primitive … Read more
