In Depth Fossils of Sibirotitan were first found in Russia during the 1950s, but not named until the disarticulated bones were put together and finally given a name in 2018. At the time of the genus description, Sibirotitan was regarded as one of the oldest titanisauriform sauropod dinosaurs on the Asian continent. Further detail than … Read more
In Depth Linhenykus has the distinctive feature of incredibly reduced arms that are typical of the alvarezsauroids. What makes Lynhenykus stand out from the group though is the fact that it had only one finger. A bone for a second finger was discovered but the nub is not thought to have been functional.

In Depth Bothriospondylus has had a long taxonomic history as a sauropod dinosaur yet today the genus is regarded as dubious. This is because the type material of Bothriospondylus, really just a few vertebrae, has been so badly eroded that it is impossible to identify any unique features for the genus. This makes it impossible … Read more

Additionally with lengths of about twenty-four and twenty-two centimetres long, the foot bones of Tochisaurus do indicate … Read more
In Depth Patagonia is a hot bed for dinosaur fossils, although it’s usually the dramatic giants such as Giganotosaurus and Argentinosaurus that that take the spotlight. Bonapartenykus was much smaller than these two dinosaurs, however for the purposes of palaeontology and understanding of Mesozoic Patagonia it is at least just as important. First is the … Read more
In Depth Bonitasaura is a genus of what seems to have been fairly small titanosaurs that lived in Argentina during the Late Cretaceous. The holotype individual seems to have been a subadult, which means that while it was sexually mature, it still would not have been fully grown. During this phase of its life though, … Read more
