Abstract The earliest occurrence of microliths in South Asia dates back to the Late Pleistocene at Mehtakheri (45 ka) and Dhaba (48 ka) in Central India, Jwalapuram 9 in Southern India (38 ka), Kana and Mahadebbara in Northeastern India (42–25 ka) and Batadomba-Lena (35–36 ka) and Fa Hien Lena (48 ka) in Sri Lanka. Microlithic technology is distributed across the entire Indian Subcontinent and chronologically continues up to the Iron Age and Early Historic periods. This chapter discusses new data acquired from the first author's doctoral research in the two districts of Madhya Pradesh (Hoshangabad – now renamed Narmadapuram – and Sehore), which fall within the central part of the Narmada Basin in central India. We present here preliminary dates from key areas of distribution to understand the geochronological contexts of microliths at Pilikarar, Morpani and Gurla-Sukkarwada. Initial dates from these respective occurrences range between 14 ka and 3 ka.

Abstract The Lower Son Valley is generally overlooked despite a lengthy history of archaeological and geological studies in the adjacent Middle Son Valley. However, recent explorations in the former have yielded a large number of Palaeolithic and microlithic sites. This paper provides an initial report on Doma, a newly discovered site with the first-known stratified bifaces in this part of the valley. The site preserves multi-period technologies in different contexts, including terminal Acheulean/early Middle Palaeolithic and Upper Palaeolithic (all tentatively assigned based on respective typologies). Preliminary field observations are presented on the sedimentary sequence, archaeological surveys, topographical mapping, raw material and the overall palaeoanthropological assessment of Doma. The raw material utilized at the site is primarily porcellanite, derived from exposures of the Semri Group of the Vindhyan Supergroup. The oldest Palaeolithic evidence at Doma broadly resembles Late Acheulean sites dated to c. 140–120 ka in the nearby Middle Son Valley. The Pleistocene sediments here also yielded mammalian fossil specimens, such as long bone fragments, dental specimens and antler fragments. Along with the lithics and fossils, the site also preserves datable sedimentary sequences with calcrete, all key proxies in developing a testable model of technological transitions within a palaeoenvironmental framework, in the future.

Abstract Progress over the last 20 years in establishing reliable benchmarks in the Paleolithic of India has been uneven but major successes have been the dating of the earliest Acheulean assemblages in India; the dating of the onset of the Middle Stone Age; the dating of the earliest microlithic assemblages in India; and the dating of the antiquity of human occupation of rain forests in South India and Sri Lanka. Also important is our greater understanding of the Younger Toba Tuff and the impact of the Toba megaeruption 74 ka ago on hominin populations in India. Major uncertainties persist over when the genus Homo first entered South Asia; when our own species, H. sapiens first entered South Asia; the age of the earliest blade assemblages in India; and the antiquity of its rock art.

Abstract Archaeological and geological remains associated with the Youngest Toba Tuff (YTT) deposits in India are seen as significant proxies for reconstructing (1) initial modern human colonization of India and (2) possible climatic impacts of the Toba super-eruption of 74 ka on the Indian climate and hominin behaviour. In order to gain further insights into the environmental impacts and behavioural adaptations of human populations in India before and after the Toba eruption, we investigated archaeological horizons associated with the Toba ash beds along the Gundlakamma basin in Prakasam District, Andhra Pradesh, India. Here, lithic artefacts were identified below and above the YTT deposits. The YTT deposits in the Gundlakamma River basin have a maximum thickness of 50 cm, comparatively thinner than those at the better investigated valleys of the adjacent Jurreru and Sagileru in Andhra Pradesh and the Son, Madhya Pradesh, India. Our surveys indicate that the Palaeolithic assemblages associated with YTT deposits from the Gundlakamma River basin can provide significant insights into the issues and debates surrounding the Toba archaeology.

Abstract Pleistocene vertebrate fossils are prominently known from several regions across the Indian Subcontinent including the Siwalik Hills, the numerous river valleys across India and some cave sites. Unfortunately, most of this evidence is lacking a robust chronological framework and very few fossil specimens have been subjected to absolute dating methods. All of the known fossil evidence is found in diverse sedimentary contexts and these faunal assemblages have mostly been assigned broad or relative age brackets such as Early Pleistocene (i.e. the Pinjore Formation of the Upper Siwalik Subgroup) and Late Pleistocene (almost all the remaining fossil vertebrate fauna in the rest of the Subcontinent). This paper discusses contextual and chronological perspectives and associated interpretative issues of open-air Pleistocene faunal sites south of the Siwalik Hills, such as north-central and peninsular India. For instance, the virtual lack of Early and Middle Pleistocene fauna across most of India requires consideration and explanations beyond just the lack of absolute dates. A general review of the known data demonstrates a critical need for absolute dates for the various fauna as well as more rigorous field and lab methods for Indian palaeontology in general, and to avoid erroneous implications for Indian palaeoanthropology.
