In Depth The type fossil material was originally assigned to the sauropod genus Bothriospondylus. However, not only is Bothriospondylus considered a dubious genus of sauropod because of the lack of identifiable features upon the type material, but the type material came from England, a long way from Madagascar. For this reason the palaeontologist Jose Bonaparte … Read more
In Depth Soriatitan is a genus of sauropod dinosaur that lived in Spain during the early Cretaceous. Although only known from partial remains, Soriatitan has been identified as a brachiosaurid sauropod, with features seen in both European and North American brachiosaurid dinosaurs.

In Depth Taveirosaurus is a tooth taxon of ornithischian dinosaur that lived in Portugal during the late Cretaceous. A tooth taxon is an animal that has only been described by teeth, and in the case of Taveirosaurus there have been many attempts to define what type of ornithiscian dinosaur that it was, almost always with … Read more
In Depth To date Ekrixinatosaurus is without doubt one of the largest abelisaurid theropods that we currently know about, and even at the lower estimate of ten meters long, Ekrixinatosaurus was still bigger than the far more famous Carnotaurus which at the time of writing seems to have had a maximum size of nine meters … Read more
In Depth Although still often regarded as a valid genus, Indosuchus is considered by some to be a nomen dubium. This is because in 1933 Charles Matley and Friedrich von Huene not only named Indosuchus, but also Indosaurus and Compsosuchus, also from partial remains. Many palaeontologists consider these three genera to possibly be the same … Read more
In Depth Buitreraptor was small, even for a dromaeosaurid dinosaur. Buitreraptor however is markedly different to most other currently known dromaeosaurid genera, especially by its skull. The jaws of Buitreraptor are long and slender, both advantages that could theoretically help in seizing prey like small lizards and mammals that might be hiding amongst rocks. The … Read more
In Depth Microceratus was actually first named all the way back in 1953 as Microceratops from partial remains discovered in the Gobi Desert of Mongolia. Just over fifty years later however it was realised that Microceratops had already been used to name a genus of wasp, and so this dinosaur was renamed as Microceratus. Microceratops … Read more
In Depth When the description of Pegomastax was first publically released news headlines of ‘Dracula dinosaur’ and ‘Fanged vampire parrot’ soon flooded the internet. Pegomastax however seems to be one of the heterodontosaurid dinosaurs, and although some palaeontologists have speculated that these kinds of dinosaurs used their teeth to eat small prey like lizards and … Read more
In Depth When Richard Owen first established the Dinosauria, and thus creating the term dinosaur in 1842, Hylaeosaurus was one of the three genera used to establish the group (the others were Megalosaurus and Iguanodon). Several species of Hylaeosaurus have been named over the years, but the only species currently thought to be valid is … Read more
In Depth Mongolostegus is a genus of stegosaurid dinosaur that lived in Asia during the early Cretaceous. Unfortunately details about Mongolostegus are hard to determine due to the overall lack of fossil remains for the genus.
