Geography
Country:Germany State/province:Bavaria County:Aichach-Friedberg
Coordinates: 48.4° North, 11.0° East (view map)
Paleocoordinates:48.7° North, 9.7° East
Basis of coordinate:stated in text
Altitude:490 meters
Time
Period:Neogene Epoch:Miocene
Stage:Langhian 10 m.y. bin:Cenozoic 5
Key time interval:Langhian Mammal zone: OSM F
Age range of interval:15.97000 - 13.82000 m.y. ago
Age estimate:14.88 ± 0.11 Ma (paleomagnetic)
Stratigraphy
Geological group:Molasse Formation:Upper Freshwater Molasse Member:Fluviatile Untere Serie
Stratigraphic resolution:bed
Stratigraphy comments: Brock horizon of the Fluviatile Untere Serie, Middle part of the Upper Freshwater Molasse (OSM), Early Badenian (Langhian).
"Fossil localities of the Brock horizon lacking fossils of the large-sized lineage of Megacricetodon Fahlbusch, 1964 are placed at the beginning of [the regional] unit OSM F (Heissig 1989, 1997; Böhme et al. 2001; Abdul Aziz et al. 2008). [...] According to the new palaeomagnetic and radiometric dating of the Ries impact event (Abdul Aziz et al. 2008), Griesbeckerzell 1a probably is approximately 14.77 Ma (14.88 ± 0.11 Ma for the Ries impact and chron C5ADr for sediments containing the Brock horizon) in age [...]" (Ivanov & Böhme, 2011).
Lithology and environment
Primary lithology: poorly lithified calcareous breccia
Secondary lithology: poorly lithified sandstone
Includes fossils?Y
Lithology description: The Brock horizon is a "limestone boulder horizon, originating from the Ries meteoritic impact" (Ivanov & Böhme, 2011). The fossils are, however, said to come from "channel-fill sands" (ibidem), apparently associated with the limestone boulders.
Environment:fine channel fill Tectonic setting:foreland basin
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils
Preservation of anatomical detail:poor
Fragmentation:frequent
Collection methods and comments
Collection methods:survey of museum collection
Reason for describing collection:taxonomic analysis
Museum repositories:BSP
Taxonomic list comments:"Interesting is the presence of a dental and a frontal bone of a possible cordylid lizard. This thermophilous family is quite common in the late Early Miocene (Roček 1984; Böhme 2002, 2010), but was not previously reported from Middle Miocene deposits of Europe." (Ivanov & Böhme, 2011)
Also, there may be mammal taxa present in the Griesbeckerzell fauna.
