Where: Champagne-Ardenne, France (49.8° N, 4.7° E: paleocoordinates 38.2° N, 13.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Marne de Flize Formation, Early/Lower Toarcian (183.0 - 182.0 Ma)

• "The "Marne de Flize" is referred to the early Toarcian (Tenuicostatum and Serpentinum zones according to Mouterde, 1980). It is therefore coeval with the Posidonienschiefer of southern Germany"

• group of beds-level stratigraphic resolution

Environment/lithology: marine; gray, blue shale and lenticular limestone

• "The finely bedded blue-grey shales are locally known as the "Marne de Flize". At La Croisette, they contained limestone lenses up to one metre in thickness"

Size classes: macrofossils, mesofossils
