Weingraben near Draßmarkt (Miocene of Austria)

Where: Austria (47.5° N, 16.4° E: paleocoordinates 46.7° N, 15.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Burdigalian (20.4 - 16.0 Ma)

• ?Helvetian

Environment/lithology: lacustrine - large; lithified mudstone

• "Congeria subglobosa. Harzhauser and Mandic (2004) suppose this large and heavily calcified bivalve to be adapted to muddy, low energetic hypolimnion environment, poor on oxygen with supersaturated sulfidic interstitial waters. It should be a significant biotope, which could play an important role in evolution of the endemic Lake Pannon fauna." Starek & Pipík, 2007. The formation of the Pannonian Basin System commenced in the Early and the Middle Miocene as the consequence of the continental collision of the African (=Apulian) and European plates, and deposition in the entire basin was influenced by important extensional tectonics.
