In Depth Named from only four caudal vertebrae, Pakisaurus is a genus that faces a future where without further remains, it will probably end up being regarded as a dubious genus. This is because even if new titanosaurian sauropod fossils are discovered, they cannot be confidently assigned to the genus unless they are found in … Read more
In Depth Minotaurasaurus was an Asian ankylosaurid dinosaur, presumably of the late Cretaceous. However the skull that makes up the holotype of Minotaurasaurus is more famous for the controversy surrounding it. The skull was purchased from a fossil dealer by Vilayanur S. Ramachandran, who in turn allowed it to be studied by palaeontologists. However at … Read more

When first described by Galton in 1978, Lesothosaurus was proposed to be an ornithopod. However the genus has also been considered to be a … Read more

In Depth Tatankacephalus is a genus of nodosaur that lived in what is now Montana during the early Cretaceous period. Best known from an incomplete skull, Tatankacephalus has been interpreted as a close relative to the better known nodosaurid dinosaur Gastonia. A different genus of nodosaurid dinosaur from the same location as Tatankacephalus is Sauropelta, … Read more
In Depth For a long time Caenagnathasia has been known from only jaw material, and even with the subsequent discovery of an upper leg bone and vertebrae, not much is known about this dinosaur. Two facts can however be established about Caenagnathasia. First, Caenagnathasia is one of if not the smallest oviraptosaur currently known. Second, … Read more
In Depth Chuanjiesaurus is a genus of sauropod dinosaur that lived in China around the mid Jurassic period.
