Fifty ditch cutting samples were analyzed for Palynological analysis. The samples were prepared based on conventional methods of maceration. Several pollen and spores present include; Zonocostites Ramonae, Monoporites annulatus, Pachydermites diederixi, Sapotaceoic sp., Verrucastoporites sp., Monocolpites sp., Acrostichum aureum and Laevigastoporites sp. There are also minor presences of fungal spores, hyphae, and dinoflagellate cysts (Botryococcus braunii). Three palynomorph zones were proposed, namely; Pachydermites diederixi, Zonocostites ramonae, and Laevigastoporites sp. Zones, having an Early to Late Miocene age. Using interpreted palynomorph data from the western section of the Niger delta, the study interval was characterized to have a wet climatic condition, due to the abundant occurrences of mangrove pollen and spores such as Zonocosites ramonae and Psilatricolporites crassus. The sediments within the studied interval include shale and sands of the paralic Agbada formation.
