Fig. 2.—Distribution of Productida (Productacea and Strophalosiacea) in Australia during the late Sakmarian and early Artinskian (e.g., Callytharra Formation, etc., of Western Australia, and Fauna II of eastern Australia = Telfordian Stage in New Zealand), each genus represented by a line generalised to suggest latitudinal extent. Fewest genera occur in Tasmania, and the number increases northwards through New South Wales and Queensland. In Western Australia a Dictyoclostid is found, member of a family not known in eastern Australia, and Wyndhamia, Terrakea, and Anidanthus with others are apparently absent. Strophalosia has been inadvertently omitted from Western Australia.
