In Depth A very interesting find, Yinlong represents the earliest identifiable ceratopsian dinosaur. Despite its small size and bipedal stance, the descendants of Yinlong would evolve into the huge quadrupedal herbivores like Triceratops that lived at the end of the Cretaceous. Study of the skull has revealed a small rostral bone, or more commonly called … Read more
In Depth Even though it did not have the elaborate horns of some ceratopsians like Einiosaurus, Pachyrhinosaurus has become a favourite amongst ceratopsian dinosaur enthusiasts because of the large bony growth called a boss that is present on top of its snout. A second smaller boss was also present over the eyes and is sometimes … Read more
In Depth Tanius is one of the many known Asian hadrosauroid dinosaurs, but one that is not very well represented. The initial description was based upon the back of the skull which seems to be that of a flat headed hadrosauroid dinosaur, the kind roughly between the earlier iguanodonts and the more advanced hadrosaurids. However … Read more
In Depth Phuwiangvenator is a genus of megaraptoran dinosaur that hunted in what is now Thailand during the Early Cretaceous. Phuwiangvenator was named alongside another theropod dinosaur called Vayuraptor, also present in the Sao Khua Formation. Care should be taken not to confuse Phuwiangvenator with Phuwiangosaurus, a titanosaurian dinosaur known from the same formation as … Read more

The species name ‘depressus’ has been retained to create the type species, which is standard procedure when naming a … Read more

In Depth Veterupristisaurus is a genus of carcharodontosaurid theropod dinosaur that lived in Africa during the late Jurassic. So far Veterupristisaurus is only known from a few vertebrae, but comparisons to Acrocanthosaurus have yielded an estimated range for the holotype individual of Veterupristisaurus of between eight and a half and ten meters in length. This … Read more
In Depth Initially described from a tibia (one of the lower leg bones), a second discovery in 2007 revealed much more of the skeleton of Condorraptor, allowing for a clearer picture of Condorraptor to come to light. Condorraptor was a mid-sized theropod that may have been similar to the famous Megalosaurus, the first dinosaur genus … Read more
In Depth Kelmayisaurus is a genus of carcharodontosaurid dinosaur that lived in China during the early Cretaceous. Kelmayisaurus is currently only known by partial upper and lower jaws, and because of this the exact size of Kelmayisaurus is still unknown. There are still reports of a second species named K. “grandis” approaching sizes of up … Read more
