Palaeontologists digging near Saint Bathans in Central Otago have discovered a fossil that probably belonged to the Southern Hemisphere’s oldest known swan species. The Bannockburn Swan lived between 16 and 19 million years ago on Lake Manuherikia, a huge lake covering most of modern Central Otago.

Joe spoke to Paul Scofield, a Senior Curator of Natural History and Adjunct Professor in Palaeontology in the Geology Department at the University of Canterbury, about the discovery.
