Wallenried WallE (Miocene of Switzerland)

Where: Fribourg, Switzerland (46.9° N, 7.1° E: paleocoordinates 45.9° N, 6.4° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: MN 2a mammal zone, Lower Freshwater Molasse Formation, Agenian (23.0 - 20.0 Ma)

• "The outcropping sediments form part of the ‘‘Molasse grise de Lausanne’’ Formation [Lower Freshwater Molasse (USM)] within the ‘‘Plateau Molasse’’ (Becker et al. 2001; Becker 2003) and are attributed to the Agenian [MN 2a] European land mammal age."

Environment/lithology: fine channel fill; fine-grained, sandy marl and sandstone

• The sedimentary architecture of the Wallenried quarry corresponds to a perennial meandering river system, with channel deposits and sandy bedforms dominated by medium to coarse sands and in decreasing granulometry from crevasse channel to floodplain deposits and/or oxbow lakes, with a predominance of fine-grained sediments. The mottled clayey to silty floodplain deposits relate to ephemeral ponds associated with seasonality in water supply.
• Sand and marl pit, the richest fossil localities comprise the base of a channel fill and fine-grained floodplain marls (e.g., WallA, WallE, WI.2, WIII.1).
