Morzadec-Kerfourn, M.-T. (1988). Palaeoclimates and palaeoenviron- ments from the Lateglacial to Recent, in the eastern Mediterranean, east of the Nile delta. the contribution of organic-walled microfossilss. Bull. Centres Rech. Ex- plor-Prod. Elf-Aquitaine, 12, 1, 267-275. (in French). Organic-walled microfossils give indications on the modifications of the marine environment, east of the Nile delta. since the Lateglacial. Among the Dinoflagellate cysts, Impagidinium spp are indicators of bathymetry in the outer neritic zone, Spiniferites bentori is associated with the beginning of the Versilian transgression near the coast, Operculodinium centrocarpum, Spiniferites mirabilis, Tectatodinium pellitum are associated with an intensification of the influence of North Atlantic water in the Mediterranean Sea, Polysphaeridium zoharyi reveals the existence of an arid period before 12 000 BP. A lacustrine alga, Pediastrum, characterizes the more humid period contemporaneous of the last cooling of the Lateglacial. Concentricystes circulus, an incertae sedis found in soils, suggests an intensification of soil erosion, after the Holocene climatic optimum.
