Evolution of the Mediterranean basin during the late Langhian early Serravallian: An integrated paleoceanographic approach

Benthic foraminifera and ostracods suggest a paleobathymetry of about 500 m and slightly under-oxygenated bottom conditions for the deposition of the sediments. Some bio-events, characterized by oligotypical assemblages (Bulimina elongata group high percentage values) indicating stressed bottom conditions and very low oxygen content, seem related to suboxic episodes.
