Abstract

The vertical distribution of significant phytoplankton, spore-pollen and foraminiferal guide fossils are detailed with special reference to palyno-stratigraphic investigations in the South Shillong Plateau. The diagnostic features of the Maestrichtian-Danian-Palaeocene intervals are summarised. Biostratigraphic evidences favour the placing of the Mesozoic-Cainozoic boundary between the Mahadeo Formation (Maestrichtian) and the overlying Langpar Formation (Danian).
