Mas d’Antrigoule farm, La Cadière-et-Cambo (Cretaceous of France)

Where: Gard, France (44.0° N, 3.8° E: paleocoordinates 34.9° N, 13.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Early/Lower Valanginian (140.2 - 136.4 Ma)

• The Valanginian age of this horizon is attested, among others, by the presence of Neocomites neocomiensis d’Orbigny, 1841 whereas further up in the formation, the presence of Eristavites Nikolov, 1966 indicates the very base of the upper Valanginian (Alabouvette et al., 1988). Thus, the sampled horizon can be considered latest early Valanginian in age.

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, hardground, shelly/skeletal marl

• Outer platform deposits
• Finely stratified calcareous marls with intercalated decimetric argillaceous limestone beds. The sampled elasmobranch-rich horizon is an indurate hardground of about 20 cm thickness including numerous bioclasts and worm tubes.

Size class: macrofossils

Collected by H. Cappetta

Collection methods: bulk, chemical, acetic, sieve
