Abstract

The new form, Wakiewakie lawsoni, is notable mainly in its extremely elongate last premolar and the hypertrophy of the mandibular foramen and masseteric canal of the mandible. The taxon not only adds to the evolutionary breadth shown by this subfamily, but appears to be one of the few potoroine genera of biochronological potential for Miocene faunas of Australia. The fossils are part of the Kutjamarpu local fauna, found in the Wipajiri Formation at Lake Ngapakaldi on the eastern margin of the Lake Eyre Basin.--Modified journal abstract.
