The productinid fauna of Cracow homestead comprises Taeniothaerus subquadratus var. cracowensis, Terrakea pollex, Anidanthus springsurensis, Cancrinella /arleyensis, H orridonia mitis and Krotovia sp., and these are described and the genera discussed herein. Comparison of this fauna with overseas assemblages shows that it is pre-Kungurian (i .e. pre-Permian, in accordance with the principle of priority of nomenclature) and post-Triticites zone of the Russian Upper Carboniferous; i.e. it is Artinskian and it seems closer to the early Artinskian ( Sakmarian ) than to the Upper Artinskian. The occurrence of species of the fauna elsewhere in Queensland is given.
THE Cracow fauna discussed herein is contained in the highly fossiliferous marine shales and limestones outcropping in a low ridge ¼ to ½ mile W. from Cracow homestead, which is about 5 miles S. of Cracow township in the Dawson Valley. The fossiliferous beds overlie Permo-Carboniferous volcanics mainly andesitic agglomerates and are overlain by massive white fine-grained siliceous sandstones with sponge spicules as the only fossils. They are about 1 00 feet thick, with 10 to 12 feet of shales at the base, then approximately 50 feet of limestone, and an uncertain thickness of calcareous sandstones now decalcified and with the fossils frequently silicified. ……………………..
