Recent discoveries of artifactual assemblages based on blade-tool technology, occuring in post-Middle Palaeolithic and pre-Mesolithic contexts in different parts of India, are filling the gap in the Indian Stone Age sequence. These lithic industries, along with the bone tools obtained from the Kurnool caves, the faunal associations at some sites, and the available radiocarbon dates, are now seen beyond doubt to represent the Upper Palaeolithic period.
