Lentille de Berru (Paleocene of France)

Also known as Berru bed 4

Where: Champagne-Ardenne, France (49.3° N, 4.2° E: paleocoordinates 43.8° N, 1.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Thanetian (59.2 - 56.0 Ma)

• said to correlate with Cernay based on the presence of P. remensis, i.e., P. tricuspidens zone, equivalent to the latest Tiffanian P. simonsi zone; Cernay is now thought to be late Thanetian

•bed 4 (Hooker and Russell 2012)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

• shelly lens

Size class: macrofossils

Collection methods: most or all material is in private collections of "Louis, Pellouin, and Poirier"
