Also known as Marnes de Dormans; Platychoerops georgei type

Where: Marne, France (49.1° N, 3.5° E: paleocoordinates 44.2° N, 0.9° E)

• coordinate based on political unit

• small collection-level geographic resolution

When: Marnes de Dormans Formation, Thanetian to Thanetian (59.2 - 48.6 Ma)

• The unit is divisible into an upper part whose base is conglomeratic ("Conglomerat a Coryphodon") and a lower part with concretionary limestone and "Paludina" aspersa. The lower part may be equivalent to the Calcaire de Rilly, which overlies the Sables de Berru and like them belongs to the Sphaerochara edda charophyte zone (Riveline 1984 : 134). Except for the Coryphodon, it is not known in which level or levels the mammals occur, as they were found in quarry spoil (Louis et al. 1983).

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size classes: macrofossils, mesofossils
