Abstract

The Upper Cenomanian ‘black shales’ at Aksudere in Crimea contain a distinct palynological association dominated by prasinophyte phycomata, mainly leiospheres and tasmanitids, and peridinioid dinoflagellate cysts, mainly Trithyrodinium suspectum ukrainense subsp. nov. Prasinophyte dominated assemblages have not previously been reported from Cenomanian–Turonian boundary organic rich deposits. Their presence confirms probable deposition under oxygen-deficient bottom waters in this area.
