Abstract:
The region of South Asia, located between the prepared core-based technologies in the west and simple core technologies in the east, is crucial in the modern human dispersal routes. The nature and chronology of initial modern human presence in the region and associated lithic technologies – microlithic vs the Middle Palaeolithic prepared core technology-are debated between the coastal and continental routes of dispersals. Recent research, however, has pushed back the antiquity of Middle Palaeolithic technology in the region to 385 ± 64 ka, suggesting the possibility of local innovation. However, the age mentioned above is isolated spatially and requires further studies to support the local innovation model. Our research in the Paleru river basin, Andhra Pradesh (SE India), have identified several Palaeolithic sites in a stratigraphic context. We present the results of a systematic examination at the Hanumanthunipadu (Andhra Pradesh) site, where the deepest of three geomorphologically distinct phases of the sedimentary sequence contained Palaeolithic artefacts. The fine-grained sediments in the sequence, p-IR-IRSL dated to > 247 ± 32 ka, yielded Middle Palaeolithic artefacts that imply South Asian Middle Palaeolithic assemblages may be a part of local innovations that emerged from the preceding Late Acheulian technologies.
