Where: Basse-Normandie, France (49.1° N, 0.2° W: paleocoordinates 39.3° N, 10.1° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Belemnopsis latesulcatus ammonoid zone, Marnes à Belemnopsis latesulcatus Formation, Middle Callovian (164.7 - 161.2 Ma)

• lower part of Middle Callovian; about 3 m below level worked by factory; also called the "Marnes d'Argences"

• bed-level stratigraphic resolution

Environment/lithology: marine; bioturbated, gray, yellow, blue, argillaceous marl and lenticular, concretionary, shelly/skeletal, gray, yellow, silty wackestone

• "blue grey to yellowish clayey marl, with lenses or thin slabs of light grey or cream-coloured biomicritic limestones. The main clay minerals are illite and kaolinite. Muscovite tiny flakes are mixed with quartzose silty clays in several beds...Muds have been slightly bioturbated and subsequently compacted...The matrix of the bones was a silty biomicrite with numerous angular quartz grains, frequent cubic crystals of pyrite, bioclasts..."
