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.

来自澳大利亚东南部悉尼盆地南部 Pebbley Beach 地层的早二叠世腕足动物

摘要 首次在澳大利亚东南部悉尼盆地南部的 Pebbley Beach 组描述了一种新的低多样性、低丰度腕足动物群，包括 4 个命名属和 3 个未确定属的 7 个物种。在所描述和图示的腕足类动物中，提出了一种新的 ingelarelloidean (Family Notospiriferidae) 物种 (Tabellina Laseroni sp. nov.) 和一种新的 terebratulid (Family Gillediidae) 属和新物种 (Paragilledia kioloaensis gen. et sp. nov.)。此外，还讨论和修订了先前从 Pebbley Beach 地层描述的两种 strophalosioidean 物种的现状和有效性。讨论了 Pebbley Beach 地层的年龄，并根据此处记录的腕足动物群以及其他地层和地质年​​代限制，被认为是晚期 Sakmarian 到早期 Kungurian。GR Shi [guang@uow.edu.au]* 和 S.
