In Depth A little known oviraptorid, Elmisaurus is based upon very few remains. Initially cited as a species of the North American Chirostenotes, it was quickly named as a distinct genus. Still, the Chirostenotes connection did not end there as in 1989 the palaeontologist Philip Currie established a second species, Elmisaurus elegans based upon oviraptorid … Read more
In Depth Stygimoloch is a dubious genus of pachycephalosaurid dinosaur as many palaeontologists are of the opinion that Stygimoloch represents a juvenile/subadult Pachycephalosaurus. In addition to this another genus named Dracorex has also been perceived to be an even younger Stygimoloch, and it is not out of the question that one day both Stygimoloch and … Read more
In Depth At over six meters long Saichania is one of the larger known ankylosaurids, although in terms of size it would probably be eclipsed by the larger Tarchia which is also known from the same formation, and was actually described at the same time as Saichania. The actual meaning of the name Saichania (beautiful … Read more
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 Burianosaurus is a genus of ornithopod dinosaur that lived in Europe during the earlier part of the late Cretaceous. Burianosaurus is named after palaeoartist Zdeněk Burian.

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
