Cadeuil amber (Cretaceous to of France)

Where: Charente-Maritime, France (45.8° N, 0.9° W: paleocoordinates 34.3° N, 1.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Late/Upper Albian to Late/Upper Albian (105.3 - 93.5 Ma)

• According to palynology, Cadeuil amber may be dated as late Albian in age (Néraudeau et al. 2002), but the horizons where the amber is found contain dynocysts, which range from the late Albian to the Cenomanian (Néraudeau et al. 2008). Similarly, the palynomorphs from the overlying subunit A2 are indicative of a latest Albian-early Cenomanian age, but ostracod and foraminifer assemblages from the upper part of subunit A1 (A1c) suggest an early Cenomanian age only (Peyrot et al. 2019). Thus, the amber from Cadeuil can be dated as latest Albian-earliest Cenomanian, although it was considered reliably dated as early Cenomanian in Perrichot et al. (2010).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; amber

• Section A1 is of brackish to coastal marine origin. A1c has cross beddings that correspond to "a succession of channels".
• "the third horizon (A1c) consists in a hard and coarse sandstone with metric cross beddings... This horizon locally includes lignite and amber" - Neraudeau et al (2008)

Size classes: mesofossils, microfossils

Preservation: soft parts, amber

Reposited in the MNHN

• Amber also stored in Department of Geosciences at the University of Rennes
