Abstract
Conodont assemblages identified as representing the Early Devonian zones of Icriodus woschmidti, Pedavis pesavis and Polygnathus gronbergi have been obtained from limestone horizons within the Cobar Supergroup. These assemblages provide the first accurate correlation for any horizons within the Supergroup. Age determinations of the Rookery Limestone and White Tank Limestone Members of the Meryula Formation suggest the presence of strike faulting not detected by field mapping. Ozarkodina druceana nom. nov. (pro Spathognathodus philipi Druce 1970) and Delotaxis tenuistriata sp. nov. are discriminated on the basis of their apparatuses of distinctive elements.Keywords
