Abstract: This work is focussed on a possible unconformity and K-T boundary in the study area. This work looks at the K-T boundary from the perspective unconformity, structural interpretation and biostratigraphy and has suggested a possible unconformity and K-T boundary around Arochukwu-Obotme-Odoro Ikpe axis. The results and interpretation of biostratigraphic analysis, fieldwork and correlation shows there is lateral continuity of lithostratigraphic units from the Arochukwu Section - Nsukka Formation (Cretaceous sediments) to the Odoro Ikpe area where it is uncomfortably overlain by the Benin Formation (younger Tertiary sediments) defining an unconformity and a possible Cretaceous – Tertiary (K –T) boundary?
