Crustaceen-Koprolithen aus der Trias der westlichen Tethys (Lienzer Dolomiten, Österreich; Pragser Dolomiten, Italien) und vom Gondwana-Westrand (oberes Magdalenatal, Kolumbien, Südamerika)

We describe Triassic Crustacean microcoprolites from the western Tethyan realm (Lienz Dolomites, Southern Alps) and from the western shores of Gondwana (upper Magdalena valley, Colombia, South America). The Colombian fauna originates from the Norian Payande Formation and represents the first discovery of microfossils in this formation. The Colombian fauna is highly diverse and shows close affinities to faunas of the western Tethyan and Mediterranean region but also to North American faunas. The form species Palaxius colombiensis and Palaxius groesseri are new, and for Palaxius shastaensis the genus Payandea n. gen. is erected. Thoronetia quinaria is revised. It is shown, that crustacean microcoprolites are a good tool for supra-regional stratigraphic correlation. Possible migration paths are discussed.
