Where: Germany (48.0° N, 7.8° E: paleocoordinates 37.0° N, 17.6° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Jurensismergel Formation, Levesquei (182.0 - 175.6 Ma)

• Bed at a depth of 94.4 m with a thickness of 0.6 m; levesquei zone; moorei subzone

• bed-level stratigraphic resolution
