Palynological evidence for a late cretaceous age for the patti formation, eastern Bida Basin, Nigeria
Three lithostratigraphic units are mappable in the eastern Bida Basin. They include from top to bottom the Agbaja Ironstone, Patti Formation, and Lokoja Sandstone. Thirty one palynomorph from species are described from the Patti formation. The Palynomorph assemblage indicates a Campano-Maastrichtian age (Upper Cretaceous) age. The Patti Formation has therefore been assigned a campano-Maastrichtian age while the underlying Lokoja Sandstone and the overlying Agbaja Ironstone both of which are barren of fossils, are either Campano-Maastrichtian or older, and Campano-Maastrichtian or younger respectively.
