Paleoceanographic reconstruction of the late Cretaceous oil shale of the Negev, Israel: Integration of geochemical, and stable isotope records of the organic matter

►We present geochemical reconstruction of the L. Cretaceous Oil Shale (OSM), Israel. ►We observed coupling between surface water productivity and sea floor conditions. ►Anoxic-dysoxic bottom water conditions are indicated by the various proxies. ►A transition in time from anoxia to dysoxia is indicated within the Oil Shale (OSM). ►The Benthic foraminifera of the OSM were adapted to minimum oxygen conditions.
