ABSTRACT
Well preserved and diverse assemblages of dinoflagellate cysts and sporomorphs, recovered from Albian-Cenomanian sediments of coastal Tanzania, include stratigraphically important dinocyst species: Dinopterygium tuberculatum Litosphaeridium arundum, Litosphaeridium conispinusum, Litosphaeridium siphoniphorum, Odontochitina operculata, Oligosphaeridium pulcherrimum, Palaeohystrichophora infusorioides, Polysphaeridium pumilum, Systematophora cretacea and several Florentinia species. The Pteridophytic spore taxa Crybelosporites pannuceus and Zlivisporites blanensis are important components of most samples. Elaterosporites klaszii which its youngest occurrence in the early Cenomanian and Elaterosporites protensus in the Albian are recorded for the first time from Cretaceous sediments in Tanzania. Gymnosperm pollen include Classopollis brasiliensis, Classopollis spinosus, Callialasporites trilobatus, Ephedripites barghoornii and Ephedripites jansonii. Angiosperm pollen are represented by Tricolpites sp. and Tricolpopollenites sp. Microthyriaceae and other fungi are also present.
