Geography
| Country: | Switzerland | State/province: | Aargau | County: | Schmiedrued |
| Coordinates: | 47.3° North, 8.1° East (view map) | ||||
| Paleocoordinates: | 47.5° North, 6.8° East | ||||
| Basis of coordinate: | stated in text | ||||
| Geographic resolution: | outcrop |
Time
| Period: | Neogene | Epoch: | Miocene |
| 10 m.y. bin: | Cenozoic 5 | ||
| Key time interval: | Middle Miocene | ||
| Age range of interval: | 15.98000 - 11.63000 m.y. ago | ||
| Age estimate: | 15.8 to 15.7 Ma (paleomagnetic) |
Stratigraphy
| Geological group: | Upper Freshwater Molasse | ||||
| Stratigraphy comments: "SP 640 and 642 are c. 15.7–15.8 m.y. old (early Middle Miocene); SP 640 corresponds to
the small-mammal unit (lower) MN 5 and to the otolith zone OT-M5b (Reichenbacher et al., 2013)." | |||||
Lithology and environment
| Primary lithology: | fine,medium sandstone | ||
| Secondary lithology: | paleosol/pedogenic,gray,green siltstone | ||
| Lithology description: The OSM sediments of SP consist of fine to medium-grained sandstones and grey to greenishmottled silts and clayswith pedogenetic overprint. | |||
| Environment: | lacustrine - small | Tectonic setting: | foreland basin |
| Geology comments: A rich and well-preserved fish fauna (otoliths, teeth) characterizes the biota of this level. Charophytes and shells of freshwater gastropods are also abundant, but gastropod shells are usually fragmented. The presence of a crocodile confirms the aquatic environment indicated by the aforementioned taxa. Shells of land snails, fragments of eggshells of a turtle, and teeth of small-bodied mammals are the main representatives of the terrestrial biota. The co-occurrence of aquatic and terrestrial taxa suggests a freshwater pond or lake and shoreline vicinity. | |||
Taphonomy
