Le Quesnoy (QNY2) (Eocene of France)

Where: Oise, France (49.3° N, 2.7° E: paleocoordinates 44.8° N, 0.0° E)

• coordinate based on nearby landmark

When: Argiles d'lignite du Soissonnais Formation, Ypresian (55.8 - 48.6 Ma)

• MP7

• group of beds-level stratigraphic resolution

Environment/lithology: fine channel fill; lenticular, gray sandstone

• Strata deposited at bottom of two channels cutting into underlying Thanetian marine green sands. The channels prograde toward the northeast and were discovered under Oise River Quaternary deposits.
• a succession of lenticular bodies showing two main facies: 1) clayey sands rich in frequently pyritised lignite, together with amber; 2) grey clayey sands with less lignite (1 to 12 % of the sediment), with continental vertebrate fauna. These facies, the rarity of mollusc shells and charophytes, probably due to decarbonatation and the presence of pyrrhotite (FeS4), reflect a hypoxic environment.

Size classes: macrofossils, microfossils

Preservation: soft parts, amber

Collected in 1997 and 1998; reposited in the MNHN

Collection methods: bulk,
