Miospores recovered from the sediments of a section of Bog-1 well in the Niger Delta Basin are assigned a Late Oligocene-Mid Miocene age, based on the co-occurrence of pantropical stratigraphic markers such as Zonocostites ramonae, Retimonocolpites pluribaculatus, Retibrevitricolporites protrudens, Psilatricolporites crassus, Circatricosisporites dorogensis, Retitricolporites irregularis, Racemonocolpites hians, Pachydermites diederixi, Brevicolpororites guinetii and Proxapertites cursus. The mainly shaly sediments were deposited in a marginally marine environment under a terrestrial influence, as indicated by the presence of very rare dinocysts, and significant amounts of cuticular material. The dominance occurrence of the mangrove species, Zonocostites ramonae (Rhizophora) and Foveotricolporites crassiexinus (Avicennia), suggests a tidal swamp shoreline inhabited by mangroves. The palynological assemblage, which is dominated by pollen and spores, consists of well preserved and diverse taxa, most of which are characteristic of dense lowland vegetation. This study reveals the dominance of a high sea level and wet climatic condition during the deposition of the studied sediments.
