In Depth Streptospondylus could have become the first dinosaur to be scientifically recognised. Starting in 1770 vertebrae and limb remains were steadily recovered and over the course of the following years many fossils for separate locations were collected before being sent to the Museum National d’Histoire Naturelle in Paris, France in 1800. These fossils were … Read more
In Depth Fossils of Bonapartesaurus were first assigned to the genus Willinakaqe. However a few years after naming Willinakaqe, Palaeontologists came to the conclusion that that genus was based upon the collection of several different kinds of hadrosaur. This included the Paratype material of Willinakaqe which became the genus Bonapartesaurus. Bonapartesaurus was a medium sized … 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 Epidexipteryx was a very special find as not only is it one of the earliest ‘dino-birds’ it also had highly ornate tail feathers. These feathers are thought to have been similar to those of a peacock, and as display feathers, possibly only present in the males for the purpose of attracting females. This … Read more
In Depth Not a lot is known about Qingxiusaurus beyond that the type fossils seem to have come from a titanosaur. Only a few bones of the anterior skeleton and fore limbs are known, making a total size of the dinosaur difficult to establish with certainty. In addition to this the location of the fossil … Read more
In Depth Tugulusaurus is a little known genus of theropod dinosaur that lived in China during the early Cretaceous. Sometimes considered to be a dubious genus, Tugulusaurus has been re-affirmed as valid as recently as the early twenty-first century. Tugulusaurus is usually attributed as a coelurosaurian theropod, though the original describer Dong Zhiming speculated that … Read more
In Depth Harpymimus was a primitive member of the Ornithomimosauria and although geographically separated by several thousand miles, similar to Pelecanimimus. Harpymimus seems to display a change in dietary focus from meat to plants, something which is indicated in the upper jaw being toothless, while the only teeth remaining in the lower jaw being small … Read more
In Depth Serendipaceratops is often regarded as a dubious dinosaur genus, but if it is not, then it is actually the first ceratopsian dinosaur to be discovered as living in Australia. The story begins in 1993 when during the Dinosaur Cove Project, an isolated almost complete ulna bone (the same as one of the ones … Read more
In Depth Since its creation Halticosaurus has had a lot of fossil remains attributed to it but most of these have been reassigned to other genera. Best known of these is the creation of a new species called H. liliensterni which ended up being raised as the genus Liliensternus in 1984. Other theropod dinosaur remains … Read more
In Depth Phyllodon is usually credited as a dubious dinosaur genus as at the time of writing only the teeth and lower jaws of this genus are known, making the attribution of new fossils difficult at best. Phyllodon however has been noted as being similar to the genera Nanosaurus. Further Reading - Teeth of ornithischian … Read more
