• A diagnostic calcareous nannofossil assemblage, representing the terminal Maastrichtian Micula prinsii zone, is discovered below the iridium-spike bearing clay-layer in the Um Sohryngkew section, Meghalaya. Its significance for the precise demarcation of the K/T boundary, providing crucial evidence for the presence of the youngest Cretaceous sediments in a continuous, bioturbation-free calcareous shale sequence, is demonstrated.
