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
In Depth Paradoxically Micropachycephalosaurus is one of the smallest dinosaurs that we know about, yet it easily has one of the longest names. Micropachycephalosaurus was named from a partially preserved individual that in 1978 was perceived as what we now call a pachycephalosaur. However more modern analysis in the early portion of the twenty-first century … Read more
In Depth Koshisaurus is a genus of primitive hadrosauroid dinosaur from the early Cretaceous of Japan. At the time of writing all known remains of Koshisaurus are partial as well as probably representing juvenile or sub adult individuals, both of which are factors that make it difficult to ascertain how big this dinosaur could grow. … Read more
In Depth Wulagasaurus is one of many hadrosaurs that have been found from the Amur River region. Although the genus is represented by a collection of scattered fossils in a bone bed, Wulagasaurus seems to have been a saurolophine hadrosaurid that was possibly related to Maiasaura and Bachylophosaurus. Wulagasaurus was not the only new hadrosaur … Read more
In Depth Another European ornithopod that was once described as a species of Camptosaurus, Cumnoria was established as a distinct genus in 1888. At three and a half meters long for the first (and at the time of writing only) individual found, it may be that Cumnoria was a fairly small ornithopod. However, studies of … Read more
In Depth Struthiosaurus seems to have been fairly common across Europe during the Late Cretaceous, a time when much of continental Europe was more like an island chain. Originally based upon fragmentary Austrian material, many genera named by Harry Govier Seeley late in the nineteenth century have now been synonymised with Struthiosaurus. This combined with … Read more
In Depth Little is known about Wannanosaurus, but the skull specimen found appears to have been from a fully grown adult as the bones that make up the skull show signs of being fused together. Wannanosaurus is considered a primitive member of the pachycephalosaurs because it has a flat skull roof and enlarged openings when … Read more
In Depth The name Echinodon means ‘hedgehog tooth’, and this is because when Richard Owen first named Echinodon in 1861, he thought he was dealing with a lizard that had a similar lifestyle to a hedgehog. Later, Echinodon was often perceived to be a primitive thyreophoran dinosaur (popularly known as an armoured dinosaur), but today … Read more
In Depth Fabrosaurus has been widely considered to be a dubious genus due to the very incomplete nature of the type remains, a partial jaw and three teeth. The better known genus Lesothosaurus however has been speculated to be a synonym to Fabrosaurus, though the lack of remains for Fabrosaurus mean that such an observation … Read more
