Nurhachius is named after the first khan of the Qing dynasty, who once ruled from the area where Nurhachius … Read more
In Depth Sapeornis is named from a combination of SAPE and the Ancient Greek ‘ornis’ which means bird. SAPE is actually an acronym for the Society of Avian Palaeontology and Evolution.

In Depth Calcarichelys was a relatively small late Cretaceous turtle but one with a highly specialised shell. Instead of the usual concave curve across the back, a series of enlarged spikes ran down the middle of the back. These are taken as being almost certainly a defensive adaptation to make it more difficult for predators … Read more
In Depth Xixiasaurus is a troodont genus thought to possibly be closely related to Byronosaurus and Urbacodon. Part of this reasoning is that the teeth of Xixiasaurus lacked serrations. Care should be taken not to confuse Xixiasaurus with the alvarezsaur genus Xixianykus that is also known from the same formation as Xixiasaurus. Further Reading - … Read more
In Depth ‘Discovered’ in a museum draw and named after the Venta River, Ventastega is a partially preserved amphibian tetrapod. Although very poorly preserved, there have been enough skeletal elements recovered to show that Ventastega had legs. These post cranial elements along with the quite well preserved skull suggest that Ventastega was more amphibian than … Read more

In Depth Losillasaurus is a member of the Turiasauria, a group sauropods which is named after the genus Turiasaurus. However Turiasaurus was named in 2006 while Losillasaurus was named in 2001, and usually this would actually make Losillasaurus the type genus since it was named earlier. Other sauropod dinosaurs that are closely related to Losillasaurus … Read more
