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

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
