Where: Germany (51.9° N, 10.5° E: paleocoordinates 43.1° N, 18.5° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Middle Kimmeridge marls Formation, Kimmeridgian (157.3 - 152.1 Ma)
• bed-level stratigraphic resolution
Environment/lithology: lithified marl
Size classes: mesofossils, microfossils
Collection methods: bulk, chemical, acetic,
• Samples with an average weight of approximately 20 kg were taken preferably from softer marl beds. The carbonate matrix was removed with 5 to 10% acetic acid. The samples were sieved with a 0.3 mm mesh. Material housed at the Institut fur Geologie und Palaontologie der Universitat Hannover.
