In Depth At the time of the genus being named, Orovenator is the oldest neodiapsid reptile known to science. The neodiapsids are the ancestral reptile group which includes most modern reptile forms. Further Reading - A new Early Permian reptile and its significance in early diapsid evolution. - Proceedings of the Royal Society B 278 … Read more
In Depth The holotype fossils of Kayentavenator were originally described as Syntarsus kayentakatae until later study declared them to represent a distinct genus of theropods (additionally Syntarsus has now been declared a synonym of Megapnosaurus). Not a lot can be said for Kayentavenator because the skeletal remains are incomplete and of a juvenile dinosaur; combined … Read more
In Depth Although so far only known from partial remains, Qiupalong has been identified as a distinct ornithomimid genus on the basis of differences in the tibia from other known genera of this group. Further analysis has led the team that described Qiupalong to consider it to be similar to Struthiomimus altus and Ornithomimus edmontonicus, … Read more
In Depth A not very well known genus of mosasaur, Ectenosaurus has still helped us to confirm that older ideas about how mosasaurs swam are simply wrong. Over a hundred years ago mosasaurs were thought to have been close relatives of snakes (again an idea that is now seen as wrong), and like them the … Read more
In Depth Riojasaurus was and still often is credited as being related to Melanorosaurus, though detailed study of the two genera does turn up some key differences. These two genera are both significant in the development of the sauropodomorphs into the large sauropods common by the late Jurassic in that they are both large and … Read more

In Depth Kaikaifilu is certainly an interesting genus of mosasaur. First it was one of the larger mosasaurs known to have been hunting in the waters of the Southern hemisphere. Also, the teeth of Kaikaifilu were heterodont, meaning that there were different forms of teeth within the mouth. This makes Kaikaifilu to be the only … Read more
In Depth Nesodactylus was actually collected way back in 1918 by Barnum Brown, but it was not until the limestone blocks that the remains were in cased were dissolved in acid in 1966 that the remains became known. Not much can be said about the diet and lifestyle of Nesodactylus except that it was a … Read more
In Depth To begin with, one of the most interesting facts about Revueltosaurus is that the genus was first believed to have represented a very primitive orithischian (bird-hipped) dinosaur. This is because when Revueltosaurus was first discovered the genus was only described by teeth, and these were very similar to the ornithiscian dinosaurs of the … Read more
