Rickenbach (Oligocene of Switzerland)

Where: Canton Solothurn, Switzerland (47.3° N, 7.9° E: paleocoordinates 47.2° N, 5.1° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: MP 29 other zone, Chattian (28.1 - 23.0 Ma)

• "Since their publication in the ‘‘International Symposium on Mammalian Biostratigraphy and Palaeoecology’’ (Engesser and Mayo 1987), Rickenbach is definitively recognised as the European mammalian reference locality for level MP29 (...) Detailed

•correlations between Swiss mammal levels and magnetostratigraphy

•were additionally published by Schlunegger et al. (1996), who clearly correlated the Rickenbach level (=MP29) within the chron 6 Cr, which actually corresponds to the interval 23.4–23.9 Ma (Fig. 1; Berger 2011)"
