In Depth An interesting little dinosaur, Dracoraptor was a small theropod dinosaur that roamed around what is now Wales during the early Jurassic. The holotype (first found) individual of Dracoraptor has been reconstructed at just over two meters in length, however, the holotype was a juvenile animal, and adults would have been larger. Dracoraptor was … Read more
In Depth Discovered in 2009 and described in 2012, Eoabelisaurus was a ground breaking discovery in our understanding of the abelisaurid theropods. So far most abelisaurids are known from the later stages of the Cretaceous period, yet the holotype Eoabelisaurus has been confidently assigned to the early stages of the Mid Jurassic. Also at around … Read more
In Depth Huaxiagnathus is one of the larger members of the compsognathid group of dinosaurs, although it is smaller than the related Sinocalliopteryx which is also from the Yixian Formation. The fore limbs of Huaxiagnathus are proportionately larger and more developed than other related dinosaurs suggesting that they had a greater role in prey capture … Read more
In Depth Afrovenator is one of the most complete theropod dinosaurs so far discovered in Africa, the harsh environmental conditions of which can quickly erode fossils exposed to the elements. Since this time Afrovenator has had a muddled taxonomic history with it being described as a relative of Spinosaurus, Eustreptospondylus, Dubreuillosaurus, Megalosaurus and even Allosaurus. … 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

Further Reading - A new caudipterid from the Lower Cretaceous of China with information on the evolution of the manus of Oviraptorosauria. - Scientific Reports. 9: Article number 6431. - Rui Qiu, Xiaolin Wang, Qiang Wang; Ning Li, … 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 Originally thought to be a juvenile of a species of Megalosaurus, Nuthetes was later established as a distinct genus. Today Nuthetes is thought to represent a possible dromaeosaurid dinosaur, but the key word here is ‘possible’. So far Nuthetes is only known from teeth and a fragment of jawbone, making such things as … Read more
In Depth There is not a lot of information about Sarcosaurus due to the relatively incomplete remains from only the pelvic region of the body. This makes it impossible to ascertain the form and structure of other body parts such as the head, hands and feet, something that makes exact classification of this dinosaur near … Read more
In Depth The Introduction of Megalosaurus to Science Megalosaurus was the dinosaur that started a great many things including the science of palaeontology, the debate about if dinosaurs should be called names that end with ‘saurus’ because they are not ‘lizards’, to lifetimes of fascination about the creatures that once walked the Earth when we … Read more
