Winterswijk Quarry III (Triassic of Netherlands)

Where: Netherlands (52.0° N, 6.8° E: paleocoordinates 16.6° N, 16.5° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Vossenveld Formation, Bithynian (247.2 - 242.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; lithified carbonate

• The presence of numerous fossil footprints (Demathieu and Oosterink 1983) together with fossil mudcracks, and wave ripples (Oosterink et al. 2003) imply a very shallow sea and periods of exposure.

Size class: macrofossils

Preservation: mold/impression
