Support for the hypothesis that dinosaurs originated in the southern areas of Pangaea are explored in a paper that was begun by Alan Charig's colleagues with his help and then finished posthumously in December of last year. The paper is the same research referenced in the radio interview posted yesterday. The paper identifies Nyasasaurus as either the earliest dinosaur or the sister taxon of the Dinosauria. The age of the fossils are explored as well, extending the origin of the Dinosauria backwards in time, making the group older than previously thought. The paper can be retrieved from an outside site not associated with the Royal Society, but be aware that there are copyright rules to be observed and respected and do not be amazed if the link stops working sometime given those things.
