Schmiedrued-Pfyffrüti (SP) 642 (Miocene of Switzerland)

Where: Aargau, Switzerland (47.3° N, 8.1° E: paleocoordinates 47.5° N, 6.8° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Freshwater Molasse Group, Middle Miocene (16.0 - 11.6 Ma)

• "SP 640 and 642 are c. 15.7–15.8 m.y. old (early Middle Miocene)"

Environment/lithology: fluvial; fine-grained, medium sandstone and paleosol/pedogenic, gray, green siltstone

• Charophytes, freshwater gastropods, remains of Unionidae, pharyngeal teeth of cyprinids and terrestrial vertebrate remains are abundant and moderately to well preserved, but otoliths are almost absent (Table 1). This fossil assemblage indicates a mixed environment in the vicinity of a river (because of the Unionidae) with an open hinterland

•(suggested by the heliophilic taxa).

• The OSM sediments of SP consist of fine to medium-grained sandstones and grey to greenishmottled silts and clayswith pedogenetic overprint.

Size classes: macrofossils, mesofossils
