Late Pleistocene microlithic industries in the Ayodhya hills, Purulia, West Bengal: Insights from geoarchaeological exploration (original) (raw)

Geological Society, London, Special Publications, 2021

Abstract

New evidence from Ayodhya hills, located in the western upland of West Bengal has expanded knowledge of a Late Pleistocene microlithic technology in South Asia spanning 42-25 ka. Continuous exploration for the past two decades has resulted in substantial information on technology, distribution of sites and the colluvial context. It is now clear from surface exploration and excavations that there are localized differences in the formation of the colluvial context. At Mahadebbera and Kana sites which have yielded the OSL dates, the Insitu occurrence of artefacts in the excavated sections confirm their association with a colluvial context. The occurrence of microliths for a prolonged period (25-34 ka) at Mahadebbera indicates that the colluvial deposition must have followed a slower rate during the course of occupation at the site. At Khududih-Chauniya, a site currently being investigated, excavation and surface exploration indicate that the artefacts are mostly scattered over the rego...
