Summary:The study of the Aquitaine Basin border (Charentes and Sarladais) makes the census of several lignitic outcrops in the Albo-Cenomanian series. Three oysters species are usually associated with these paralic deposits. These taxa are revised for their systematic and palaeoecological features. Acutostrea lingularis is the most-typical brackish species and is especially abundant in massive lignitic wood accumulations. Gyrostrea delettrei is a small robust species that is able to colonize high-hydrodynamics estuarine channels with wood deposits. Striostrea sp., belonging to a Recent genus, is well developed on various terrigenous substrates with wood fragments from euryhaline palaeoenvironments.
