Bed 24, Kernbohrung/Tongrube Wittnau, Baden-Württemberg (Jurassic of Germany)

Where: Germany (48.0° N, 7.8° E: paleocoordinates 37.4° N, 17.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Jurensismergel Formation, Early/Lower Aalenian (175.6 - 171.6 Ma)

• bed at depth 78.7 m with a thickness of 1.4 m; opalinum zone; torulosum subzone

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, shelly/skeletal claystone

• In the south-german basin (Süddeutsches Becken) located at the northern margin of the Thetys. About 50 km away from shore
• In this part of the Jurensismergel (jurensemarl) the quite fast and constant sedimentation is characterized by mostly strong Bositra-accumulations. The high content of lime results in so called Tutenmergel layers and lenses. Lime and pyrite nodules are less common in this part.

Size classes: macrofossils, microfossils

Collection methods: bulk, core,
