Impagidinium bacatum, a new Dinoflagellate cyst species from the Mediterranean Pliocene: systematics, biostratigraphy and paleoecology

Laurent Londeix; Mohamed Benzakour; Anne de Vernal

Abstract Impagidinium bacatum nov. sp. is a dinoflagellate cyst with a relatively thick and punctate wall and which has been exclusively observed in the Mediterranean Sea sediments of Early Pliocene and Late Pliocene ages (ca. 4.3–2.4 Ma). Its maximum abundance was found to occur in upper Pliocene laminites in association with other dinoflagellate cyst taxa that have a thick and ornamented cyst wall such as Achomosphaera callosa, Operculodinium israelianum and Tectatodinium pellitum. Impagidinium bacatum was probably a warm-temperate to subtropical, stenothermic species, rather tolerant toward salinity conditions.
