THE CENOZOIC BRACHIOPODA OF THE BREMER AND EUCLA BASINS, SOUTHWEST WESTERN AUSTRALIA

WA Museum Records and Supplements | Updated 1 decade ago

Abstract - The brachiopod fauna from the Late Eocene Bremer Basin and Middle Eocene to Pliocene Eucla Basin are described. Nineteen species have been recorded from the six major deposits in the two basins. Two new species, Terebratlllina christopheri and Liothyrella labiata, are described. Two described species are re assigned from Terebratula to Liothyrella: T. bulbosa (Tate, 1880) and T. sllbcamea (Tate, 1880). The close relationship between the species found in the basins and those found in Late Eocene to Miocene deposits in southeastern Australia is examined. The later appearance of species in eastern South Australia, Victoria and Tasmania may well accord with the separation of Australia from Antarctica. The relationship between genera in Australia, New Zealand and Antarctica is also examined with implications for the evolution of Southern Hemisphere Brachiopoda.
