Bed 49, Kernbohrung Wittnau, Baden-Württemberg (Jurassic of Germany)

Where: Germany (48.0° N, 7.8° E: paleocoordinates 37.1° N, 17.6° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Jurensismergel Formation, Toarcian (182.7 - 174.1 Ma)

• Bed at a depth of 94.9 m with a thickness of 0.5 m; levesquei zone; moorei subzone

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified claystone

• In the south-german basin (Süddeutsches Becken) located at the northern margin of the Thetys. About 50 km away from shore
• The beds frequently contain accumulated biodetritus, mainly Echinodermata-debris and Bivalve-shell. The marly claystone is subdivided through layers of pyrite nodules, accumulations of limeconcretions and finley distributed Bivalve-(Bositra)-shell, having a quite disturbed sedimentsuccesion.
