Sample B -23, Bédat section, Tercis-les-Bains (Cretaceous of France)

Where: Landes, France (43.7° N, 1.1° W: paleocoordinates 35.9° N, 0.8° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• Abathomphalus mayaroensis (in thin section) about 25 meters below the Bédat Wall suggests that the corresponding upper Maastrichtian begins at least this level. The Bédat Wall itself and overlying levels contain diagnostic Palaeogene globigerinids.

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, cherty/siliceous limestone

Size class: macrofossils
