Wenlock (Early Silurian) Brachiopods from the Orane District of New South Wales

Two late Wenlock (Early Silurian) brachiopod species from the Ulah Formation near Orange, New South Wales, are closely associated with graptolite faunas. Visbyella cumnockensis occurs in the testis Biozone on Wallace Creek in the Four Mile Creek area, and Strophochonetes melbournensis is recorded from the ludensis Biozone on Spring Creek. Poorly preserved but similar Visbyella? and Strophochonetes? From the Prídolí Wallace Shale at Cheesemans Creek are also illustrated. These occurrences provide significant new stratigraphic and distributional data for the species.
