Where: Germany (48.2° N, 8.8° E: paleocoordinates 37.4° N, 18.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Middle Toarcian to Middle Toarcian (182.0 - 175.6 Ma)

• From jurense-Bank, an 8 cm thick marl interval. Crinoids come from matrix washings from ammonoid blocks, so it's not possible to determine whether they came from the lower or upper part of the bank. Probably came from lower part because hanging wall is poor in crinoids. Collection 31987 is combination of samples 1-4, but they are not separated in that reference.

• bed-level stratigraphic resolution

Environment/lithology: lithified marl

Size class: macrofossils

Collected in 1990; reposited in the SMNS
