In Depth Guanlong is well-known among palaeontological circles as the first tyrannosaur, although new discoveries in the future may take this epithet away from Guanlong. The discovery of Guanlong lends support to the theory that the early origins of the tyrannosaurs can be traced back to Asia. From here fossil evidence from the discovery of … Read more
In Depth Fukuiraptor is a dinosaur that really does not deserve the ‘raptor’ part of its name. This is because when it was discovered, one of the large hand claws was interpreted as being a ‘killing claw’ on the second toe, similar to other dromaeosaurids that have the epithet raptor. Later analysis resulted in a … Read more
In Depth Discovered back in the early days of scientific palaeontology, Eudes-Deslongchamp named the species Poekilopleuron bucklandii in honour of William Buckland, the man who named the first ever known dinosaur Megalosaurus. Additionally Eudes-Deslongchamp thought that Poekilopleuron may actually be the same species of dinosaur as Megalosaurus, an idea shared by the palaeontologists Fredriech von … Read more

In Depth Genyodectes was first named in 1901 by A. S. Woodward who described it upon the basis of partial premaxilla and maxilla bones as well as a dentary. Because of the lack of other fossils the genus languished in relative obscurity for over a hundred years, with occasional references citing Genyodectes as a nomen … Read more
In Depth What information can be garnered about Hypselosaurus is that it was a medium sized titanosaur that lived in what is now Western Europe at the end of the Cretaceous period. Unfortunately it is very difficult to go beyond this because of the incomplete nature of recovered specimens (despite the popular image presented in … Read more

In Depth Like with many early theropods, especially European ones, Metriacanthosaurus was originally named as a species of Megalosaurus, a dinosaur that in the early years of palaeontology ended up being used as a wastebasket taxon for almost any theropod remains. The initial naming was made by the German palaeontologist Friedrich von Huene, who named … Read more
In Depth Changyuraptor is another of an increasing number of dromaeosaurid dinosaurs that have been dubbed ‘four-winged dromaeosaurs’. This is because Changyuraptor did not just have well developed pennaceous feathers on the arms; they also grew from the back of the legs. The first of these dromaeosaurs to be described was Microraptor which is speculated … Read more
