Implication

This analysis identifies biostratigraphic zones in calcareous nannoplanktons, suggesting paleoenvironmental shifts in the Dahomey Basin.

Key Points

  • The biostratigraphic analysis identified two distinct zones, NP24 or younger and NN11 or older, reflecting significant geological epochs.
  • Calcareous nannofossil species served as proxies for past marine conditions, informing on temperature fluctuations and nutrient availability.
  • Detailed examination involved 51 ditch-cutting samples, showcasing a comprehensive approach to sedimentary environment reconstruction.
  • These findings indicate a dynamic interplay of climatic factors affecting the offshore Dahomey Basin during the Late Oligocene to Late Miocene.
