Where: Champagne-Ardenne, France (49.3° N, 4.0° E: paleocoordinates 43.8° N, 1.6° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: MP6 mammal zone, Thanetian (59.2 - 56.0 Ma)
• Marnes de Montchenot
•
•Most fossil mammals come from levels E and F of Laurain and Henry (1968), which were also sampled most extensively, but fossils still occur further down in the section, including the top of level D.
•
•European mammalian reference level MP6
• group of beds-level stratigraphic resolution
Environment/lithology: pond; marl
•
•"in a relatively quiet environment, probably a pond behind a dune belt … where the slow movement of waves on the shorelines induced the regular turning over of the oncolithes"
•
•"quiet freshwater milieu and are suggestive of coastal marshes"
Size class: mesofossils
Reposited in the MNHN
