In Depth The name Leinkupal means ‘vanishing family’, and this is a reference to the observation that the diplodocid sauropods seemed to have died out during the early Cretaceous. Indeed, at the time of its description, Leinkupal seems to have been one of the last diplodocid sauropods known to live, though other types of sauropods, … Read more

In Depth Cionodon is a dubious genus of hadrosaur that is based only upon very partial and fragmentary remains. So far two species of Cionodon continue to exist, but because of the poor quality of their fossils, it is next to impossible to assigned further remains to them, or even to identify them as synonymous … Read more
In Depth Lukousaurus is a little known reptile that is probably a theropod dinosaur, possibly of the Ceratosauria. The overall lack of fossil remains for the genus however makes it very difficult to be certain about exactly what kind of creature Lukousaurus was. Further Reading – Preliminary notes on the Lufeng vertebrate fossils. – Bulletin … Read more
In Depth Fossils of Kaatedocus were first recovered in 1934 and subsequently assigned to the genus Barosaurus. Later study of the fossils revealed them to actually represent a distinct genus of diplodocid sauropod. Further Reading - The skull and neck of a new flagellicaudatan sauropod from the Morrison Formation and its implication for the evolution … Read more
In Depth One of the earliest known ankylosaurs, Shamosaurus is regarded as being very similar to Gobisaurus, however there is enough fine detail differences in the skulls of the two genera that palaeontologists are confident in assigning these two ankylosaurs as separate genera. Unfortunately there are not yet enough remains to confidently estimate the size … Read more
In Depth Not a lot can be said about Pawpawsaurus because so far it is only known by a skull. However, another nodosaur from the Paw Paw Formation is Texasetes (which includes post cranial remains), which has been suggested as being a synonym to Pawpawsaurus. If this is true, then the current Pawpawsaurus fossil material, … Read more
In Depth Barsboldia is so far only known from vertebrae and some fragmentary remains of other parts of the post cranial skeleton. At the time of writing no skull is known for the genus, yet the original describers still chose to class Barsboldia as a lambeosaurine hadrosaurid dinosaur. Later studies however have cast doubts about … Read more
In Depth Cathayornis is a genus of enantiornithine bird that lived in China during the early Cretaceous. While the type species of Cathayornis, C. yandica is valid, two further species C. aberransis and C. chabuensis have also been named but are questionable as they consist of partial body parts that are not preserved in with … Read more
In Depth The holotype fossil of a partial jaw of Regnosaurus was recovered by Gideon Mantell who considered it to belong to an unknown large prehistoric animal. Mantell would later name his animal Igaunodon, though it was still referred to as a big lizard since the word dinosaur had still not been invented. Mantell realised … Read more
