In Depth The almost complete specimen of Monolophosaurus was first discovered in 1984. This exciting find was initially named ‘Jiangjunmiaosaurus’ after Jiangjunmiao, an abandoned inn near where the skeleton was found, but it was never an official name hence the lack of italics and its description as a nomen nudum (a name that is not … Read more
In Depth One of the troodonts, Byronosaurus aquired its name after being named after Byron Jaffe, a supporter of the American Museum of Natural History Paleontological Expeditions. One of the unearthed skulls of B. jaffei is the best persevered skull specimen of any troodont, and shows two adaptions that are unique among the currently known … Read more
In Depth Although as the name suggests this was the first dromaeosaurid to be discovered, it was not well understood until some of the other dromaeosaurids were discovered and studied. This has allowed for the gaps to be filled in, giving a much more accurate representation of what Dromaeosaurus was like. While Dromaeosaurus still had … Read more

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.

In Depth Fossils of Cruxicheiros were first discovered in 1960 when they were discovered in the Cross Hand Quarry of Warwickshire, which as you have no doubt already realised is the inspiration for the name Cruxicheiros which means ‘Cross Hand’. At the time the fossils were just lumped in with Megalosaurus, which has for a … Read more
In Depth There is a lot of mystery surrounding Iliosuchus as the genus is only based upon the description of three ilia. These parts are not diagnostic enough to clearly identify what kind of theropod dinosaur Iliosuchus was, though in England during the Mid Jurassic the dominant theropod dinosaurs were the megalosaurs. A similarity to … Read more
In Depth Although Deinonychus was first discovered in 1931, it would not be until the 1960s with the advent of more discoveries that it would get named and studied in detail. These studies helped lead to one of the most radical ideas put forward in the field of palaeontology; at least some of the dinosaurs … Read more
In Depth Afrovenator is one of the most complete theropod dinosaurs so far discovered in Africa, the harsh environmental conditions of which can quickly erode fossils exposed to the elements. Since this time Afrovenator has had a muddled taxonomic history with it being described as a relative of Spinosaurus, Eustreptospondylus, Dubreuillosaurus, Megalosaurus and even Allosaurus. … Read more
In Depth With greatly elongated fingers the hands are a tantalising find for palaeontologists, but without the rest of the skeleton it is impossible to give an accurate insight into this creature’s life. One possible explanation is that Yixianosaurus lived like a modern day aye-aye. Aye-aye’s also have hands that have impressively long fingers which … Read more
