Problematical microfossils from the Cretaceous and Palaeocene of the Middle East

During studies of the non-foraminiferal microfossils, especially the algae, of the Middle East over the last decade a considerable number of problematical organisms have been noted. These include some whose allocation is doubtful, at varying taxonomic levels, or whose position has only recently been established, as well as new or unusual examples of known families and genera. A selection of these, Cretaceous and Palaeocene in age, is now placed on record as a further contribution to Tethyan micropalaeontology.
