Stratigraphy
Stratigraphy comments: "Suevium moyen"
According to Heissig (1984) the sediments are not in layers, do not indicate any fluviatile current, and the distribution of the fossils in the karstic system is irregular.
JA: Suevian is early Oligocene

Primary lithology: "siliciclastic"
Lithology description: Sediments of Ronheim first described by Trischler and Winkler (1968).
Environment:lacustrine indet.
Geology comments: Interpreted as "a field of fresh water (Lake, mud pit)."
