In the time of Joan Wiffen's theropod, the continent Tasmantis had split off from Gondwana, meaning that this theropod dinosaur must have been unique to NZ, which scientists believe was much closer to the South Pole.
All of the finds at the Tahora Formation are from the Cretaceous period, and have all been found by amateur palaeontologist Joan Wiffen and her fossil-hunting team.
