Taxonomy and phytoecology of palynomorphs and non-pollen palynomorphs: a refined compendium from the West Africa Margin

Due to the high diversification and complex nature of low latitude tropical pollen research in palynology and palaeobotany, most researchers are often faced with difficulties in taxonomic identification and grouping of species into their family affinity. This identification and grouping are necessary in order to reflect the vegetational and ecological dynamics rather than assuming a species entity based on their morphology alone. This study present a hamonised taxonimic and photomontage update of sphoromorphs and non-pollen palynomorphs (NPPs) in relation to their phytoecology, biogeography and family/ botanical affinities from the Niger Delta (Figure 1). The monotonous taxonomy, phytoecology, biogeography and family/botanical affinities complexities of species has been existing since its commencement.1 This practice is through evaluation and comparison of morphological description and identification of sporomorphs (pollen and spores) and NPPs with modern material. Later, several compendia for pollen, spores and NPP identification have been documented from different region worldwide.2–6 The reliability of the information provided by palaeobotanists and palynologists to the study of palynomorph and NPPs is dependent on accurate visualisation or, where possible, identification and confirmation of the strewn mount assessed from the processed slides.
