Abstract
A new low-diversity and low-abundance brachiopod fauna comprising seven species in four named genera and three indeterminate genera is described for the first time from the Pebbley Beach Formation in the southern Sydney Basin, southeastern Australia. Among the brachiopods described and illustrated, one new ingelarelloidean (Family Notospiriferidae) species (Tabellina laseroni sp. nov.) and one new terebratulid (Family Gillediidae) genus and new species (Paragilledia kioloaensis gen. et sp. nov.) are proposed. In addition, the status and validity of two strophalosioidean species previously described from the Pebbley Beach Formation are also discussed and revised. The age of the Pebbley Beach Formation is discussed and, based on the brachiopod fauna documented here and other stratigraphic and geochronological constraints, is considered to be late Sakmarian to early Kungurian.
