Paleoecological control of ostracode distribution in a Pennsylvanian Auernig cyclothem of the Carnic Alps, Austria

Fohrer, Beate ; Samankassou, Elias

In: Palaeogeography, Palaeoclimatology, Palaeoecology, 2005, vol. 225(1-4), p. 317

Pennsylvanian (Kasimovian) ostracodes from the lower part of the Auernig Group, Carnic Alps, Austria, inhabited a shallow-marine and open-marine environment. Paleontological investigations of two ostracode faunas brought significant differences between the ostracode assemblage of the Anthracoporella (dasycladalean algae) mound environment and the one from the overlying nodular limestone....

Drowning of algal mounds : records from the Upper Carboniferous Lower Pseudoschwagerina Limestone, Carnic Alps, Austria

Samankassou, Elias

In: Sedimentary Geology, 1999, vol. 127, no. 3, p. 209-220

Anthracoporella algal mounds, up to 22 m thick, occur within the cyclic sequences of the Lower Pseudoschwagerina Limestone (uppermost Carboniferous), Carnic Alps (Austria). Their depositional environment lay between the wave base and the base of the photic zone. The algal mounds are overlain by dark, well-bedded, cherty wackestones and packstones. The cherty limestones contain cephalopods,...
