Where: Germany (47.9° N, 8.7° E: paleocoordinates 37.5° N, 18.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Brasilia bradfordensis ammonoid zone, Hauptbank Formation, Middle Aalenian (175.6 - 171.6 Ma)

• This seems to be correlative with the Opalinus Clay. 15–25 cm thick, nodular bed, which occurs below the 45–60 cm thick, chamositeoolitic “Hauptbank“. The age of this bed therefore lies around the boundary of the Bradfordensis-/Gigantea subzones of the Bradfordensis Zone.

• bed-level stratigraphic resolution

Environment/lithology: lithified, nodular marl

Size class: macrofossils
