In Depth Due to the incomplete nature of the holotype fossils, Ultrasaurus is today seen as a dubious genus of sauropod dinosaur, given that it would be near impossible to attribute further remains to the genus. Ultrasaurus is actually more famous for forcing a naming change in a North American genus of diplodocid dinosaur. In … Read more
In Depth Remains of Brazilian dinosaurs are often noted as being incomplete (for example, the increasingly famous spinosaurid Oxalaia was named from only the tip of the snout), and Adamantisaurus was no exception to this since it was named from only six caudal vertebrae. These six vertebrae were originally written about in 1959 by Sergio … Read more
