Biostratigraphic investigation in the Middle Triassic sediments of Liechtenstein and Vorarlberg (Austria)

The biostratigraphic framework of the Arlberg area has never been studied in detail. Therefore, we established detailed profiles of the Middle Triassic basins and platforms. The aim of the study was a reliable (biostratigraphic) correlation of the Eastern Alps and the Southern Alps. This will help to construct an enhanced palaeogeographic pattern of this area. Our reconstructions, based on bivalves, palynomorphs, and lithological correlations, overcome the stratigraphic problems which prevailed due to the scarcity of ammonoids in the sections.
