In Depth Silvisaurus is to date only known by a partial skeleton, and this is in a poor state of preservation that was weathered and trampled by cattle for a long time before it was discovered. Despite the poor state of preservation, Silvisaurus is considered to have been a primitive form of nodosaur that maybe … Read more
In Depth With an estimated length of around three meters long Anserimimus was towards the smaller end of the scale in terms of ornithomimosaur size. Other related dinosaurs from the same area such as Gallimius would have been at least double this size, while the very incomplete Deinocheirus would have been even larger than this. … Read more
In Depth Atsinganosaurus is named from the Ancient Greek word atsinganos which means ‘gypsy’, and is a reference to a proposed east to west migration for these dinosaurs. The known remains of Atsinganosaurus are fragmentary but in otherwise a good state of preservation. Unfortunately the overall lack of them means that it is hard to … Read more
In Depth Initially considered to be a Southern population of Massospondylus, Adeopapposaurus was established as an independent genus in 2009. Adeopapposaurus is an unusual sauropodomorph since it appears to have had a keratinous beak to its mouth. If correct, then this may have been a feeding specialisation for snipping off foliage from plants. Further Reading … Read more
In Depth With its incredibly long neck Omeisaurus is both a relative and possible comtempory to the more famous Mamenchisaurus. However previous Upper Shaximiao Formation fossils of Omeisaurus are now considered indeterminate. If Omeisaurus really does only exist in Lower Shaximiao deposits, then it may confirm that Mamenchisaurus replaced Omeisaurus since the former is only … Read more
In Depth Mendozasaurus is a genus of titanosaur that lived in South America during the late Cretaceous. Although only known from incomplete remains, Mendozasaurus is thought to have had quite a long neck as well as osteoderms in the skin. Osteoderm armour in the skin has been observed in some other South American titanosaurs, with … Read more

In Depth Epichirostenotes was originally discovered in 1923 before being described in 1997 as a specimen of Chirostenotes pergracilis by Hans-Dieter Sues. Further study and description in 2011 saw this specimen described as its own genus. The type species E. curriei is in honour of the palaeontologist Philip Currie. Although only known from incomplete material, … Read more
In Depth Sarcolestes is a genus of ankylosaur that lived in England during the mid-Jurassic. Unfortunately the only part of this dinosaur that is known is a lower jaw bone, so it is difficult to infer much more about this dinosaur. The lack of fossil remains has also cast doubt upon the validity of this … Read more
