Abstract
The marginiferid Retimarginifera Waterhouse 1970 is reviewed and a new species, R. waterhousei, is described from the Kungurian Coolkilya Greywacke of the Carnarvon Basin. Retimarginifera is a characteristic genus of the Cimmerian Province of the Gondwanan Realm with a limited number of species penetrating the Westralian Province. Occurrences beyond the Gondwanan Realm require confirmation.
