In Depth Eoraptor stands out not only for being one of the first dinosaurs to ever walk the Earth, but because palaeontologists cannot conclusively agree on where to place it in relation to other dinosaurs. Initially Eoraptor was classed as a theropod because of its bipedal stance and narrow build, but the sauropodomorphs (which would … Read more
In Depth Fossils of Platypelta have for a long time been associated with the genus Euoplocephalus, yet in 2018, some of these fossils were given their own distinct genus by Penkalski in 2018. Platypelta was a medium sized ankylosaurine dinosaur that lived in North America during the late Cretaceous. Further Reading - Revised systematics … Read more
In Depth Latenivenatrix has a somewhat convoluted history of discovery. The holotype specimen of the genus (CMN 12340) was originally designated as being a Stenonychosaurus by Dale A. Russel in 1969. Then in 1987 it was moved into the Troodon genus, the type genus of the troodontid dinosaurs. It was not until much later in … Read more
In Depth Unfortunately at the time of the genus description the only fossils of Austroposeidon that we have are some vertebrae. However, comparison to other similar dinosaurs has led to realistic size estimates for this dinosaur of about twenty-five metres in length. Although not the biggest dinosaur, this does make Austroposeidon at the time of … Read more
In Depth Massospondylus was one amongst the first dinosaurs to be named with a taxonomic history going back as far as the mid nineteenth century. Yet when Richard Owen described the first fossils, he thought that he was dealing with an ancient ancestor to more familiar lizards such as iguanas chameleons. In actuality Massospondylus represents … Read more
In Depth Hypselospinus was a genus of ornithopod that was similar to Iguanodon, so similar in fact that the holotype remains of the genus were originally named as a species of Iguanodon, I. fittoni. These remains were re-described as a new genus by Norman in 2010, but not long after another name for the remains … Read more
In Depth Fossils of Dinheirosaurus were first treated as belonging to Lourinhasaurus until new study ascertained that they were of a different genus. For some time afterwards there was still speculation that this was a mistake and that Dinheirosaurus should be regarded as a synonym to Lourinhasaurus, but even further study has now established without … Read more
In Depth In 2006 the palaeontologists M. Sadiq Malkani managed to name five titanosaurs from the Pab Formation of Pakistan, all described from caudal (tail) vertebrae. Malkani also named two new families of titanosaurs, the Pakisauridae and the Balochisauridae as homes for the new titanosaurs. Balochisaurus as you may have guessed is the type genus … Read more
In Depth Not a lot of information is currently available about Delapparentia, though as a relative to herbivorous dinosaurs like Iguanodon, a few things can be inferred. Delapparentia would have been a fairly large ornithopod dinosaur that would have balanced most of its body weight upon its rear legs, while the fore legs were reduced … 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
