Untereichen-Altenstadt 540m (Miocene of Germany)

Also known as UA 540m

Where: Bavaria, Germany (48.2° N, 10.1° E: paleocoordinates 48.4° N, 8.4° E)

• coordinate estimated from map

When: Untere Fluviatile Serie Member (Upper Freshwater Molasse Formation), Burdigalian (20.4 - 16.0 Ma)

Environment/lithology: levee; paleosol/pedogenic, fine-grained, sandy siltstone and marl
