Carboniferous and early Permian brachiopods from Western and Northern Australia

Most of the Carboniferous brachiopods (excepting productoids and rhynchonellids) so far collected from the Carnarvon, Canning (Fitzroy), and Bonaparte Gulf Basins of Northwest Australia are described. The faunas of the Bonaparte Gulf Basin are the least well represented. Six Carboniferous brachiopod zonal assemblages are distinguished: two of Tournaisian, one of late Tournaisian. to possibly Visean, two of Visean and one of late Visean to possibly Namurian age. The described faunas include species of Rhipidomella, Leptagonia, Schellwienella, Schuchertella, Rugosochonetes?, Prospira, Unispirifer, Spirifer, Anthracospirifer, Ectochoristites?, Brachythyris, Kitakamithyris, Torynifer?, Syringothyris, Punctospirifer, Cleiothyridina, Composita, and an unnamed new spiriferid genus. At least 23 species are new. Affinities with world-wide Dinantian faunas are suggested for the majority. The brachiopods are distributed through the Moogooree Limestone and Yindagindy Formations of the Carnarvon Basin, the Laurel Formation of the Fitzroy Basin, and the Burt Range Formation, Enga Sandstone, Septimus Limestone, Utting Calcarenite, Burvill Beds and Point Spring Sandstone of the Bonaparte Gulf Basin. Four Permian spiriferacean species are also described from the Carnarvon and Canning Basins. They comprise the Sakmarian Lyons Group species Trigonotreta narsarhensis occidentalis subsp. nov., and Cyrtella nagmargensis australis subsp. nov., and the Artinskian Pseudosyringothyris dickinsi sp. novo from the Callytharra Formation and Pseudosyrinx? sinuosa sp. novo from the Madeline Formation. The species support a correlation of the Lyons Group with the Umaria beds of India, part of the Agglomeratic Slate of Kashmir, and early Permian beds of Arabia. Boreal affinities are suggested for P. dickinsi sp. Novo Generic morphological features are discussed. Points of interest include the composite nature of the dental plates in Schellwienella, the initial dental plates of certain Spiriferidae, the adductor muscle attachment function of the syrinx in Syringothyris and the adductor muscle scars on the delthyrial plate in Pseudosyringothyris. The taxonomy of certain families is discussed, notably the Syringothyridae.
