Schematic description of the sedimentological situation (left), outcrop photographs, and event stratigraphic interpretion of the sedimentologic succession (right) in the Josefstobel (Hochgeländ plateau south of Biberach an der Riß; outcrop no. 3 in the text). Two seismic events (Ries and Steinheim impact-earthquakes) are reported by the occurrence of two independent seismite horizons with slumps and convolute bedding within sediments that formed the land surface at the time of the two impact events. Additionally, the Steinheim impact-earthquake caused the formation of clastic dikes in deeper parts of the affected sediments. Usually, the Ries seismite is capped by distal Ries ejecta in several outcrops in the Hochgeländ area and elsewhere. In the Josefstobel, the distal Ries ejecta horizon is substituted by a dark claystone layer that resembles the K-Pg boundary layer to a certain degree (all photographs taken by V.J.S. in 2021).
