In Depth Fulgurotherium is a little known genus of Australian dinosaur that is also known from very little fossil material; at the time of writing, only a fragment of a femur. This femur seems to match up small ornithopod dinosaurs that range about one to one and a half meters long in size, but this … Read more
In Depth In 2006 the palaeontologists M. Sadiq Malkani described five new genera of titanosaur, Marisaurus, Balochisaurus, Sulaimanisaurus, Khetranisaurus and Pakisaurus, all from caudal vertebrae. From these only Marisaurus and Balochisaurus have had skull remains attributed to them, and only Marisaurus has (partial) rear limb bones attributed to the genus. Marisaurus and Balochisaurus were also … Read more
In Depth Uberabatitan is a genus of titanosaurid sauropod dinosaur that is known from the Marilla Formation of the bauru group of Brazil. Being Maastrichtian in age, Uberabatitan would have been one of the last titanosaurs to live before the KT extinction ended the reign of the dinosaurs.

In Depth Beibeilong is a genus of oviraptorid dinosaur that lived in Asia during the earlier stages of the late Cretaceous. The genus was described from fossilised embryos and eggs. Adult details including maximum size of Beibeilong are unknown at the time of writing, but the original describers of the genus speculated that when fully … Read more
In Depth Ojoraptorsaurus is a genus of oviraptosaur that lived in what is now New Mexico during the earlier stage of the Maastrichtian. Although only named from fossilised pubis bones, Ojoraptorsaurus has been identified as a caenagnathid oviraptosaur, making it a closer relative to genera such as Elmisaurus and Gigantoraptor. With the holotype fossils of … Read more
In Depth Loricatosaurus was named as part of a study that concluded that the type species of Lexovisaurus was based upon un-diagnostic material, and that other remains cannot be attributed to it. Although many palaeontologists still treat Lexovisaurus as a valid genus, many of the fossils once assigned to it have now been named as … Read more
In Depth Borealosaurus is a genus of titanosaurid dinosaur that lived in China around the boundary of the early/late Cretaceous. Though only known from partial remains, Borealosaurus has been interpreted as being potentially related to the better known Opisthocoelicaudia. In addition to this the Japanese titanosaur Fukuititan has also been interpreted as a close relation … Read more
In Depth Many people often think that Sinraptor will be another dromaeosaurid dinosaur, when in actual fact it was a medium sized theropod of a similar build to Allosaurus. This is not the first instance that a non dromaeosaurid dinosaur has been given the inclusion of ‘raptor’ in its name with others such as Fukuiraptor … Read more
