In Depth Fossils of Citipes were first described in 1933, but as a species of Ornithomimus. After this they subsequently moved into the Elmisaurus and Leptorhynchos genera respectively, before finally being described as a distinct genus in 2020. Citipes is a genus of oviraptosaur dinosaur that lived in North America during the late Cretaceous. Further … Read more
In Depth With a name that translates to English as ‘Monstrous murderer’, Teratophoneus has arguably one of the most apt names of any dinosaur, although the remains suggest that it was smaller than many of the other tyrannosaurids. The species name, T.curriei, is in honour of palaeontologist Philip J. Currie. Teratophoneus was a very interesting … Read more
In Depth The holotype fossils of Antetonitrus were originally found in 1981, but were thought to be further fossils of the genus Euskelosaurus. It was not until over two decades later that they would be correctly described as a distinct genus. Antetonitrus is a very interesting sauropod dinosaur, as while it was quadrupedal (walked on … Read more
In Depth In 1876 Richard Owen named a new species of Poekilopleuron called P. pusillus. In 1879 this species was adjusted to P. minor by Edward Drinker Cope. Then in 1887 Harry Govier Seeley renamed this species as a new distinct genus, Aristosuchus. However, despite the name ‘suchus’ which is Ancient Greek for crocodile, this … Read more
In Depth Daemonosaurus has a distinguished skull that is unlike any other dinosaur currently known from the time. The upper teeth are mounted in a short snout and protrude forwards from the tip. This is mirrored in the lower jaw and was the inspiration for the type species name D. chauliodus that loosely translated means … Read more
In Depth Dahalokely is so far only known by very incomplete remains, but if it’s identification as an abelisauroid is correct, then it certainly was very small for its type. Alternatively, if Dahalokely turns out to be a noasaur, a group of theropods closely related to abelisaurs, then it would be expected to have a … Read more
In Depth Dyslocosaurus is a genus of diplodocid sauropod dinosaur that lived in North America during the late Jurassic. It is unknown exactly where the type fossils of Dyslocosaurus are known from as when they were first discovered they only had ‘Lance Creek’ written on them. There is a Lance Formation that is named after … Read more

In Depth Based upon the description of a partial skull, the validity of the Stormbergia genus has been questioned as some have proposed that the skull may represent the fully grown adult form of Lesothosaurus. If this is correct then Stormbergia would actually be a synonym to Lesothosaurus. Further Reading - The ‘fabrosaurid’ ornithischian dinosaurs … Read more
In Depth Chenanisaurus is a genus of abelisaurid dinosaur that lived in North Africa towards the end of the Cretaceous period. Chenanisaurus is named from the description of a partial lower jaw, and while this does not give us much to go on, it does reveal a few things. While the jaw is incomplete, it … Read more
