Social legacy and geoheritage significance of the largely overlooked Catahoula Volcanic Ash of South Texas
Abstract The Oligocene–Miocene Catahoula Formation occurs along the length of the Gulf of Mexico coastal plain from the Rio Grande to the state of Mississippi. In Starr County, in South Texas, the formation is typified by the 20 m-thick Catahoula Volcanic Ash, interpreted to represent a single caldera eruption. The massive ash fall is the main source of the uranium that has been mined in South Texas since the late 1950s. It is also the origin of massive amounts of petrified wood, which was used in prehistory for making projectile points and continues to be used for landscaping. Diagenetic alteration of the volcanic ash produced the distinctive El Sauz Chert, which was used by native Americans for 10 000 years to make projectile points. More recently, the Catahoula Volcanic Ash was used as pozzolanic aggregate with Portland cement for the construction of Falcon Dam. The outcrop of the Catahoula Volcanic Ash in Starr County is the centrepiece of a geoheritage initiative, titled ‘ Ancient Landscapes of South Texas at the Nexus of Natural and Cultural History ’, whose goal is to connect the earth and social sciences to educate residents, students and visitors in how the region's geology has played a significant role in its social history.
Indigenous knowledge of palaeontology in Africa
Abstract Compared to other continents, the study of indigenous (non-western) knowledge of palaeontology in Africa is a relatively new field. The literature reviewed here nevertheless suggests a long-lasting string of traditions, geomyths and folklore related to fossilized items on the whole continent and encompassing many African cultures. It is often difficult to estimate the antiquity of these traditions, but the evidence gathered here suggests that they range from the 1800s to pre-colonial times, and up to many millennia. Palaeontological items were collected and used for a variety of reasons, but the African record seems unusual for its scarce use of fossils for traditional medicine. Also, despite substantial efforts, some famous localities with conspicuous fossils still remain without any documented indigenous knowledge. We stress that documenting fossil-related folklore and geomyths is not only a matter of preserving this knowledge or promoting diversity, but is also crucial for establishing strong bonds with local stakeholders to encourage preservation of geoheritage and discover new sites.

Acheulian artefacts and tephra from Upland Western Maharashtra (Deccan Volcanic Province), Peninsular India
Abstract The two Early Acheulian sites of Bori and Morgaon in the Deccan Volcanic Province in Upland Maharashtra, India bear some association with an acidic tephra deposit in a fluvial context. Acheulian artefacts in association with tephra were first reported in India from the Bori site and numerous efforts to date this tephra have since been undertaken. These efforts employed various dating methods and produced a total of 10 absolute dates ranging from the Early Pleistocene with a maximum age of 1.4 Ma to the Late Pleistocene with a minimum age of 23.4 ± 2.4 ka. However, field observations and a typo-technological analysis strongly suggests that these Early Acheulian artefacts occur in a semi-primary context, and thus contest the Late Pleistocene age of the tephra and redeposition of the artefacts as argued by some scholars. At Morgaon, the Acheulian artefacts have been recovered from basal fluvial sediments that contain clasts of laterite. These sediments are capped by two low-energy clay facies that are separated by high-energy gravel lenses. The tephra at Morgaon has been reported from the upper clay facies and has produced absolute dates ranging from the Matuyama period (>0.78 Ma) to the Late Pleistocene (41 ka). After more than two decades of investigation at these sites, the number of absolute dates procured through methods such as electron spin resonance (ESR), 39 Ar– 40 Ar, U–Th and palaeomagnetism, although encouraging, are inconclusive. This paper is therefore an attempt to gauge the nature of the palaeolandscapes that most probably existed during the Early Quaternary. This will be achieved by studying local geomorphological variability between the two sites, along with a preliminary analysis of lithic morphology.
Spatial distribution of Palaeolithic sites in relation to raw material sources in the central Narmada Valley, India
Abstract Landscape adaptation in central India is quite exceptional, as more than 300 Lower Palaeolithic occurrences have been reported in different contexts. The present work deals with these assemblages and associated raw material sources in the central Narmada Valley. The central Narmada Valley is rich in various rock types that were used as raw material by various hominin populations. The Narmada River divides the region into northern and southern parts. In the north, there are mainly the Vindhyan Supergroup and Deccan Trap, whereas, in the south, there are primarily the Gondwana Supergroup, the Deccan Traps and the Mahakoshal Group. Along the river, there are exposures of the Vindhyan Supergroup and thick deposits of Quaternary alluvium. The main raw material types in the north of Narmada are quartzite and sandstone (Vindhyan Supergroup), whereas, in the south of Narmada, the main raw materials are quartzite (Gondwana Supergroup) and chert (Deccan Trap). Acheulean sites are mostly found along the foothills of Vindhyan, as well as along the banks of the Narmada River and its tributaries. In this chapter, the author has tried to link these raw material sources with the occurrences of Palaeolithic sites in order to have a better understanding of past hominin land-use patterns and ecological adaptations.
Absence does not mean absence: modern-day land use and the visibility of the archaeological record (the Kibbanahalli Palaeolithic Complex, southern India)
Abstract Kibbanahalli is an important Lower Palaeolithic site-complex in southern Karnataka, a state in the southern region of Peninsular India. This region is crucial as it is somewhat centrally located between areas to the north, east and south, where decades of systematic Palaeolithic research has led to the establishment of firm cultural stratigraphy(ies) and even, in some cases, of chronology(ies). However, in stark contrast to these regions, southern Karnataka is often ignored in prehistoric research. Over 90 years of (intermittent) investigations at this site-complex have laid the foundations of our understanding of the Palaeolithic occupation of this region. It is of utmost importance to continue Palaeolithic research in this area as it is one of the fastest-growing industrializing and urbanizing zones of the world, with large population centres such as Bangalore (Bengaluru), Mysore (Mysuru) and others located here. Documenting the rich Palaeolithic heritage in this region before its eventual surrender to the forces of ‘development’ is thus a priority. Further, it is also necessary, if possible, to qualify and quantify the impact of these developmental processes on the visibility and preservation of the archaeological record, in general, and the Palaeolithic record, in particular, which might serve as a model for future research in similar regions. These recent investigations have led to the identification of many new Palaeolithic localities, and a secure identification of the technological attribution of their lithic assemblages. The presence of a uniform stratigraphic association of the archaeological horizon and similarities in their lithic collections has led to the reclassification of the many localities at Kibbanahalli and its vicinity into a site-complex. This paper reports on a series of field observations and remotely sensed data collected to understand the distribution pattern of the various Palaeolithic localities of this site-complex. Results of this study highlight the critical role played by modern-day land-use patterns on the observed distribution of the archaeological record, as well as its visibility. This observation challenges previous interpretations regarding the settlement patterns and strategies suggested for the Palaeolithic occupation of this region. Further, this study draws attention to the need and necessity to understand the role of various site formation processes, especially modern-day land-use activities, on the observed and observable patterns in the archaeological record, as well as the visibility, or lack thereof, of the archaeological record.
Doma: a new multi-technological lithic occurrence in the Lower Son Valley (north-central India) and its regional context
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 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 New evidence from the Ayodhya Hills, located in the western upland of West Bengal, has expanded knowledge of Late Pleistocene microlithic technology spanning 42–25 ka in South Asia. 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 the Mahadebbera and Kana sites, which have yielded optically stimulated luminescence (OSL) dates, the in situ occurrence of artefacts in the excavated sections confirm their association with the 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 regolith surface capping the bedrock; much of the colluvial material from the site has been eroded and transported downslope, exposing the lithic artefacts over the regolithic badland surface. Added interest in this site ensues from recent finds of Middle Paleolithic cores and a Lower Paleolithic core from the badland rain gullies. This promises to complement the already published results from the region, which has emerged as an important zone in understanding the behaviour patterns of anatomically modern humans in South Asia.
Abstract The Spiti Valley is located in the Trans-Himalayan terrain of India, from where non-geometrical microliths have been discovered. While the Siwalik Hills have been subjected to extensive prehistoric surveys, this is the first evidence of lithic tools discovered in the Trans-Himalayan region of Himachal Pradesh, India. Due to its topographical and intense climatic features, the Trans-Himalayan region has generally been regarded as a barrier since prehistoric times. However, Dzamathang cannot be considered as an isolated site in the Trans-Himalayas. In fact, in the adjoining areas of Ladakh, Tibet and Nepal, similar lithics have been reported from several sites and been assigned to the Middle and Upper Palaeolithic. The discovery of this site suggests that the Trans-Himalayan zone may have acted as a possible route rather than a barrier during human migration. Large numbers of lithics have been recovered in the Dzamathang area of the Spiti Valley. Based on the collection of the artefacts from the surface, this paper tries to understand the geological and geographical setting of the area, particularly concerning prehistoric settlements in the Trans-Himalayas. This assemblage consists of assorted artefacts, which include a unifacial chopper, microlithic cores, flakes, blades, bladelets, burin and a large amount of debitage fragments. The majority of artefacts are on quartzite or quartzarenite. Future surveys will be targeted at recovering primary context sites for excavations and absolute dating.
New evidence of Neolithic industries from the West Garo Hills, northeastern India
Abstract This paper is based on the field investigations conducted in the West Garo Hills of northeastern India. The work presents a brief report on the Neolithic manufacturing sites of the West Garo Hills. It addresses the various issues of lithic sequence, typological classifications, lithic technology, settlement pattern and site distribution pattern of the known sites and newly discovered sites in the West Garo Hills. Large clusters of Neolithic manufacturing sites have been located on the hilltops and hillslopes close to present-day rivers, streams, natural springs, water channels and modern Garo community habitats. Dolerite raw materials were mostly preferred for fashioning the artefacts, and manufacturing units are found close to the dyke basalt rock sources. Findings of habitation deposits or pottery are very sparse; however, evidence of plant and animal domestication, burial, bone tools, and metal use pose new hypotheses on their use owing to poor preservation. The Palaeolithic evidence and the region's transition to early farming cultures remain vague.
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 An understanding of long-term climate variability may provide a valuable perspective on the possible response of human societies to modern climate change. The present study, based on geochemical and sedimentological analyses on well dated (using AMS 14 C and optically stimulated luminescence (OSL) dates) alluvial sediments from Sina River basin (in Maharashtra, central India), provides a detailed understanding of the complex interplay between climate and cultural dynamics during the Late Holocene. The radiocarbon dates of the organic residues from the potsherds represent the Medieval period ( c. 1.6–0.95 cal ka BP), whereas the OSL sample shows an age of c. 7.5 ± 0.4 ka. Further, several cultural objects (e.g. potsherds, shell bangles, and copper artefacts) available at the site were also investigated in order to understand the extent of human activity in the region. The temporal changes in the proxies along with the abundance of cultural materials in the fluvial section during the Medieval period suggest that the human population attempted to adapt against the fluctuating climate conditions. The regional comparison of geo-archaeological datasets shows that the pronounced weakening of the monsoonal rainfall during the Late Holocene coincides with the disruption, migration and resettlement of indigenous societies, deciphering the possible impact of climate on human settlement.
