| Summary: | The very high Cretaceous ammonite fauna from the area close to Tercis-les-Bains has been revised. Even the lower (but not lowest) part of the Grande Carriere is already near the top of the Campanian, belonging to the Zone of Nostoceras hyatti This assemblage is comparable to that found in the Zone of Pseudokossmaticeras tercense in the region of the Bay of Biscay, and to that found in the Zone of Nostoceras pozaryskii of the Vistula Valley in Poland. The lowest occurrence of the overlying Zone of Pachydiscus epiplectus, and the lowest Maastrichtian recognisable in ammonite terms, is marked by the incoming of Hoploscaphites constrictus. A higher ammonite Zone of Menuites [Anapachydiscus] fresvillensis has been detected only from museum specimens from La Pointe to the north of the Grande Carriere. The highest Maastrichtian ammonite zone in the Biscay region is that of Menuites [Anapachydiscus] terminus. This has not been detected near Tercis. -from Authors |
