Micropalaeontology. Only the non-age-diagnostic, quasi-marine, smaller benthonic foraminifer Elphidium stellatum was recorded by Imnadze & Karmishina (1980) from the Late Pontian (Bosporian sub-stage) of the Black Sea. Stratigraphically and/or palaeoenvironmentally significant ostracods recorded by Sheydayeva-Kuliyeva (1966) and Azizbekov (1972) from the Pontian of Azerbaijan (Western Caspian), by Karmishina (1975) from the Northern Precaspian and South-Eastern Kalmyk (Northern Caspian) and Prechernomore (Northern Black Sea), and by Vekua (1975) from Abkhazia (north-eastern Black Sea) include Bakunella dorsoacuata, Caspiolla acronasuta, Pontoniella acuminata and P. loczyi. Bakunella dorsoacuata and Caspiolla acronasuta are quasi-marine species (Yassini, 1986). Species of Leptocythere, Loxoconcha and Xestolehris also occur. It is possible to recognise three ostracod zones in the Pontian of Eastern Azerbaijan (Sheydayeva-Kuliyeva, 1966). It is also possible to recognise three corresponding mollusc zones. The lower part of the Continental (Cheleken) Series of Northern Iran and the Maragheh Bone Beds of Central Iran can be correlated with the Pontian on vertebrate palaeontological, limited malacological and ostracod evidence (Faridi, 1964; Stocklin & Setudehnia, 1971, 1972). Palynology. Only non-age-diagnostic palynomorphs have been recorded from the Pontian. Pollen spectra from the Pontian of i Georgia are characterised by relatively high incidences of tropical elements such as Nypa (palm) (Ramishvili, 1969). Those from the Late Pontian (Bosporian sub-stage) of the Ukraine are characterised initially by thermophilic (wa
