摘要

This report is the synthesis of the field workudand discussions held during the workshop «PaIaeontology andudbiostratigraphy of Toarcian-Bajocian Pelagic Carbonate PIatformsudammonitiferous sediments of umbro-marchean Apennines:udthe Monte Nerone area. Correlations with other westernudTethys regions» (Piobbico, CentraI ItaIy, august 2-14, 1993).udIt presents a preliminary proposition of biohorizons forudrock correlation in the investigated area, following the proposaisudof Italian Commission on Stratigraphy on definition ofudbiostratigraphic units.udThe sampied «body of rock strata» consists on 113 beds,ud25,60 metres thick, where 30 biostratigraphic surfaces (biohorizons)udhas been recognized.
