Le Quoniam near Haravilliers (Pacaud collection) (Eocene of France)

Where: France (49.2° N, 2.0° E: paleocoordinates 47.1° N, 1.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: NP 16-17 nannofossil zone, Sables de Cresnes Formation, Bartonian (41.3 - 38.0 Ma)

• The Cresnes and Marines sands are referred to the middle Eocene, and more precisely to either the NP 16 biozone (Aubry 1988) or the NP 17 biozone (Aubry 1983, 1988 ; Cavelier & Pomerol 1983). "Marinesian" in local stratigraphy.

• group of beds-level stratigraphic resolution

Environment/lithology: foreshore; poorly lithified, coarse-grained sandstone

• A mediolittoral community living on hard substrates (Lozouet & Maestrati 1994: 166; Dolin & Pacaud 2000: 54). The dynamics of the environment was sufficient to accumulate some terrestrial and lagoonal species as well.

Size class: macrofossils

Collected by J.M. Pacaud; reposited in the MNHN
