  Paleoecological conditions of part of Gombe formation of Upper Benue Trough were studied using outcrop samples from 22 sites of 1.5 m deep each. The samples were crushed, standard maceration method employed for analysis and slides prepared. The slides were examined for identification and counting using transmitted light microscope with times one hundred oil immersion objective lenses. The result showed a fairly rich assemblage of palynomorph which includes age diagnostic palynomorphs: Cingulatisporites ornatus, Proteacidites sigalli, Constructipollenites inflectus, Echitriporites trianguliformis, Longapertites microfoveilatus, Monocolpites sp. and Tricolpites sp. which effectively assigned the upper Maastritchtian age to the sequence. Also the abundance of woody and vegetal materials which are land derived in the shales, siltstones and kaolinite rich claystone at the.. View More»
