Abstract
Moreover, the P/G ratio, the relative abundances of the dinoflagellate cyst assemblages and other palynological parameters were used successfully to reveal the palaeodepositional settings of the identified PEZ and GEZ. Alternating, transgressive and regressive phases were identified, although a dissimilar species composition is observed in each of these ecozones. Environments were interchanging between the regressive, marginal marine to proximal inner neritic and the transgressive, distal inner to middle shelf settings. Three peridiniacean dinoflagellate cyst peaks were recorded, the middle Cenomanian Subtilisphaera peak, the middle Coniacian Isabelidinium, Chatangiella, and Manumiella peak, and the middle Santonian Isabelidinium peak.
