[The palaeobiological record of Pleistocene anoxic levels in the Samoggia section (northern Apennines)]. The integrated study of planktic and benthic assemblages of foraminifera from the Samoggia River section (northern Apennines, Italy), allows reconstruction of paleoenvironmental scenarios during the early Pleistocene. Up to 24 sapropels have been recognized in the section. The faunal succession suggests a basin with low salinity in the upper part of the water column and low oxygen content at the sea-bottom. High-resolution micropaleontological investigations allow identification of two intervals characterized by different paleoclimatic and paleoenvironmental conditions: the lower one starting from the Plio-Pleistocene boundary to 1.5 Ma, and the upper one from 1.5 Ma to 1.31 Ma.
