Brachiopods of the Yarralumla Formation (Ludlovian), Canberra, Australia

Abstract

Abstract The Yarralumla Formation of Canberra has been considered the stratigraphic equivalent of the earliest Ludlovian Yass Formation of the Yass Syncline north of Canberra. The previously unpublished brachiopod fauna of the Yarralumla Formation is fully described; comparison with that of the Yass Formation confirms approximate age equivalence. Of the eleven species, none of which is new, eight also occur in or a little above the Yass Formation.
