In Depth Surprisingly what is perhaps the most important ornithomimosaur so far discovered by the early twentyfirst century is also one of the least known outside of palaeontology. Initially thought to be a primitive ornithomimosaur, Sinornithomimus is now thought to be quite a bit more advanced than early ornithomimosaurs like Harpymimus, but not quite as … Read more
In Depth Xixiposaurus is a genus of sauropodomorph dinosaur that lived in China during the early Jurassic. Further Reading - [A new prosauropod dinosaur from Lower Jurassic in Lufeng of Yunnan]. - Global Geology 29(1):6-15. - T. Sekiya - 2010.
In Depth Dallasaurus was a fascinating discovery, especially for lovers of the marine reptiles that swam the Mesozoic oceans, more particularly the mosasaurs of the Cretaceous. The skeletal features of Dallasaurus have helped to further cement the theory that the mosasaurs evolved from terrestrial (land living) reptiles like monitor lizards during the early/mid Cretaceous. A … Read more

In Depth Today Antarctica is often referred to as a frozen wasteland, but back in the Jurassic it actually had an extensive covering of forest, something which is confirmed by the presence of fossilised tree trunks found near the remains of Cryolophosaurus. Many of the early Jurassic theropods had display features on top of their … Read more
In Depth Eohupehsuchus is a genus of hupehsuchian reptile that lived in China during the early Triassic. The name Eohupehsuchus means ‘dawn Hupehsuchus’, a reference to its similarity but earlier appearance to the Hupehsuchus genus. Further Reading - A Small Short-Necked Hupehsuchian from the Lower Triassic of Hubei Province, China. - PLOS ONE 9 (12. … Read more

In Depth Garudimimus is considered to be an ornithomimosaur, but unlike others of its kind it had shorter ilia, the legs were shorter and the muscles not as well developed. This has led to speculation that Garudimimus would have actually been quite slow for an ornithomimosaur, although it could still probably out pace a human … Read more
In Depth Originally thought to be a cynodont, Lycorhinus was not realised to be a dinosaur until 1962 when Alfred Walter Crompton studied the holotype. Many remains have been attributed Lycorhinus in the past, but most of these have now been moved to other species of different genera, two examples being UCL A100 and UCL … Read more
In Depth The discovery of Padillasaurus has been a very important step in South American palaeontology as it represents the first confirmed genus of a brachiosaurid sauropod dinosaur that is known on this continent (though isolated and very fragmentary remains have been found before, they were not complete enough to name a genus). Unfortunately the … Read more
