In Depth With the skull being wider than it is long, Jeholpterus has the same basic skull morphology consistent with all anurognathid pterosaurs. Most of the teeth are small but some are longer and recurved (backwards towards the mouth). The claws of the hands and feet are long and curved, longer on the hands, meaning … Read more
In Depth Cetiosauriscus is often confused with the similarly named Cetiosaurus, and this is no accident. The name Cetiosauriscus means ‘whale-lizard-like’, a reference to Cetiosaurus which itself means ‘whale-lizard’, so when Friedrich von Huene named the genus in 1927, he was actually saying that Cetiosauriscus was similar to Cetiosaurus. When the genus was first named … Read more
In Depth Found almost complete, Heyuannia was the first oviraptorid to be discovered within the borders of mainland China, specifically Guangdong Province. Up until the description of Heyuannia, other Asian oviraptorids were all discovered in Mongolia. Going by the holotype individual, Heyuannia seems to have been a small mid-sized genus of oviraptorid. The skull of … Read more
In Depth The discovery of Xiaotingia caused some upset in the paleontological community because of its similarities to the world famous Archaeopteryx which has been hailed as the first bird since its discovery in 1861. This is because Xiaotingia is thought to be a dinosaur that is similar to a bird rather than a bird … Read more
In Depth Lazarussuchus was named after the figure of Lazarus of Bethany in the Bible, a person in the Gospel of John who was resurrected four days after his death by Jesus Christ. The relevance here is that the holotype remains of Lazarussuchus were found from a late Oligocene deposit, a period many millions of … Read more
In Depth Until 1970, Daspletosaurus was thought to be another specimen of Gorgosaurus. Both were active at the same time and location as one another, yet closer study of the Daspletosaurus revealed a much more powerful animal than the more lightly built Gorgosaurus. It has been surmised that the two predators may have focused their … Read more
In Depth Vancleavea is a quite unusual genus of reptile as it is quite unlike any other known reptile. Vancleavea had a long body, thick bones, short limbs and a particularly dense and robust skull. Thick bones such as these are commonly seen in reptiles that spend lots of time swimming under the surface of … Read more
In Depth Originally named as a species of Rhynchosaurus, R. brodiei was established as a distinct genus in 2016 and granted the name Langeronyx. As a rhynchosaur Langeronyx would have been a squat plant eating reptile that lived during the Triassic.

In Depth Not much is known about this dinosaur except that the forelimbs appear to be quite large for a large carnivorous theropod. The discoverer theorised that it may of actually been quadrupedal, but this has since been refuted by other palaeontologists. Further Reading – [A new theropod dinosaur from the Middle Jurassic of Sichuan … Read more
In Depth Qiupanykus is a genus of alvarezasurid dinosaur that lived in Asia towards the end of the Cretaceous. Eggs of oviraptorid dinosaurs found near the holotype skeleton of Qiupanykus have led the describers of the genus that maybe Qiupanykus, and perhaps other alvarezsaurs, used the stout claws on their forelimbs to punch holes in … Read more
