Grignon (Defrance collection) (Eocene of France)

Where: France (48.8° N, 1.9° E: paleocoordinates 45.7° N, 1.6° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: NP15 nannofossil zone, Lutetian (47.8 - 41.3 Ma)

• The sediments from the "Falunière de Grignon" are correlated of the Middle Lutetian, according to the identification of biozone NP15 (Aubry 1985). They belong to the regional Zone III and the base of Zone IV of Abrard (1925) and correspond to parasequences A6-A10 of Gely (1996).

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; unlithified, calcareous sandstone and unlithified, glauconitic sandstone

Size class: macrofossils

Preservation: original aragonite

Reposited in the MNHN

• Repository: Defrance collection (some of which is now at Musée de Normandie, Caen, or at MNHN Paris)
