Where: Baden-Württenburg, Germany (48.6° N, 9.5° E: paleocoordinates 37.8° N, 17.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Posidonia Shale Formation, Early/Lower Toarcian (183.0 - 182.0 Ma)

• Lias epsilon II/4 (Unterer Schiefer). Tenuicostatum/Falciferum zones.

Environment/lithology: marine; lithified shale

Size class: macrofossils

Collection methods: The localities of the types of the new species cannot be specified in greater detail. The specimens were recovered in the first half of the 20th century from small temporary quarries which were opened in the Posidonia shale of the Holzmaden/Ohmden area. All of the quarries existed only for a short time and their exact positions are unknown today. Specimens at the Urweltmuseum Hauff Holzmaden.
