Pine Nut Use in the Early Holocene and Beyond: The Danger Cave Archaeobotanical Record

Nuts of limber pine (Pinus flexilis) from Early Holocene strata in Danger Cave, Utah, are distinguishable by seed-coat sculpturing from pine nuts of single-needled pinyon (Pinus monophylla), which occur in strata dating <7000 years . Owls and other taphonomic agents may deposit pine nuts in archaeological sites, but the morphology of the pine nuts in Danger Cave strongly indicate they were deposited by human foragers who brought small quantities with them for food for at least the last 7500 years. Large-scale transport of pine nuts to Danger Cave from distant hinterlands is unlikely, however. The seamless transition from limber pine to pinyon pine nuts in the Danger Cave record suggests that foragers who had utilized limber pine as a food resource easily switched to using pinyon pine nuts when pinyon pine migrated into the region at the close of the Early Holocene.     

Diversity of cultivars and other plant resources used at habitation sites in the Llanos de Mojos, Beni, Bolivia: evidence from macrobotanical remains, starch grains, and phytoliths

Although sparsely populated today, the Llanos de Mojos, Bolivia, sustained large sedentary societies in the Late Holocene (ca. 500 to 1400 AD). In order to gain insight into the subsistence of these people, we undertook macrobotanical and phytolith analyses of sediment samples, and starch grain and phytolith analyses of artifact residues, from four large habitation sites within this region. Macrobotanical remains show the presence of maize (Zea mays), squash (Cucurbita sp.), peanut (Arachis hypogaea), cotton (Gossypium sp.), and palm fruits (Arecaceae). Microbotanical results confirm the widespread use of maize at all sites, along with manioc (Manihot esculenta), squash, and yam (Dioscorea sp.). These integrated results present the first comprehensive archaeobotanical evidence of the diversity of plants cultivated, processed, and consumed, by the pre-Hispanic inhabitants of the Amazonian lowlands of Bolivia.     

Stable isotope analysis of dog,fox, and human diets at a Late Holocene Chumash village (CA-SRI-2) on Santa Rosa Island,California

Stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope analyses of dog (Canis familiaris), island fox (Urocyon littoralis), and human bone collagen from CA-SRI-2 (AD 130–1830) on Santa Rosa Island, California provide a proxy of diet and the relationships between humans and these animals. Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods. Nitrogen isotopes and archaeofaunal remains indicate that humans and dogs also ate higher trophic level foods, including finfishes, marine mammals, and seabirds with smaller amounts of shellfish. The CA-SRI-2 island foxes appear to have eaten higher amounts of terrestrial foods, similar to the diets observed in modern fox populations. These data generally confirm the commensal relationship assumed to exist between domesticated dogs and people, but the carbon isotopic composition of dogs is enriched ∼2‰ compared to humans. We hypothesize that the difference in carbon isotopes between dogs and humans may have resulted from a higher consumption of C3 plants with lower δ¹³C values by humans, or less likely from the ingestion by dogs of significant amounts of bone collagen, which is enriched by ∼4‰ over associated muscle.     

WHAT’S FOR DINNER? INVESTIGATING FOOD-PROCESSING TECHNOLOGIES AT DUST CAVE,ALABAMA

Abstract

Many models of hunter-gatherer subsistence have traditionally focused almost exclusively on what people ate. More recently, researchers have begun to ask how these ancient foods were processed and prepared prior to consumption, questions that are best answered by looking at the context in which food remains are uncovered. At the archaeological site of Dust Cave (1Lu496), excellent preservation conditions have resulted in a plethora of cooking features. Ranging from small charcoal pits to fired clay surfaces and hearths, the features at Dust Cave are in-situ representations of the occupants’ cooking and processing activities. We use a combination of paleoethnobotanical, zooarchaeological, geoarchaeological, and experimental methods to investigate these activities. Experimental studies were conducted in order to develop archaeological correlates for food processing. Experimental results are then compared to botanical and faunal remains from the site as well as chemical analyses of feature fill. Results suggest that the occupants of Dust Cave likely processed fish and plants–primarily nuts–on a large scale. Specifically, fish appear to have been roasted in coals, plants and nuts toasted or parched on flat clay “griddle-like” surfaces, and hickory nuts boiled in pit hearths to extract nut oil.     

Starch analysis reveals prehistoric plant translocations and shell tool use,Marquesas Islands,Polynesia

Starch analysis is proving particularly useful in tropical regions like the central Pacific where crop inventories are often dominated by starchy fruits and tubers and recovery of macrobotanical remains is rare. Analysis of 23 shell tools from the Marquesas Islands provides direct evidence for translocation of five traditional crop plants. Four taxa derive from the western Pacific, including Artocarpus altilis (breadfruit), Piper methysticum (kava), Colocasia esculenta (taro), and one or more species of Dioscorea (yam). The fifth taxon, the South American Ipomoea batatas (sweet potato), dates from the 14th century AD onward and constitutes the earliest record of this cultigen in the archipelago. The occurrence of sweet potato starch suggests that this crop plant may have been more important than usually is assumed, while the limited recovery of breadfruit starch, the main Marquesan food plant at western contact, requires further investigation. The starch residues also inform on tool use, demonstrating that shell tools ethnographically associated with specific crops (e.g., “breadfruit peelers”) had more generalised functions. This study is a further demonstration of the potential of starch analysis to provide important information on the history of crop introductions, on-site activities, and artefact use.     

The Scandinavian reindeer (Rangifer tarandus L.) after the last glacial maximum: time,seasonality and human exploitation

Antlers and bones of reindeer (Rangifer tarandus L.) are the most frequently found vertebrate remains from the Late Glacial deposits of Southern Scandinavia. The Danish collection now consists of more than 350 specimens and of these 47 have been radiocarbon dated extending the range of occurrence in the area with ca. 1300 ¹⁴C yr. Thus the first occurrence is pushed back to ca. 12?500 ¹⁴C yr BP (late Bølling chronozone) while the youngest date lies at ca. 9200 ¹⁴C yr BP (late Preboreal chronozone) establishing that the reindeer survives well into the Holocene. The seasonal dates of the reindeer indicate for the first human occupation (the Havelte group from the Bølling period) a summer, autumn and early winter occupation, with reindeer, as well as man, apparently being absent during the coldest winter months. Finally, it is shown that Southern Scandinavia acted as a calving area throughout the Late Glacial and Early Holocene thus discrediting the North–South model of reindeer groups moving from a wintering area in Southern Scandinavia to a calving area in the foothills of the North European plain.     

The mobile herding economy of Kebarah Cave,Mt carmel: An economic analysis of the faunal remains

The faunal remains from Kebarah Cave provide evidence of the economic activities of the cave's inhabitants during the late Pleistocene and early Holocene. The variety of grazing resources around the cave is reflected in the proportions of the several species exploited, which changes gradually over time. A comparison of Bos remains indicates that locational factors appear to outweigh any chronological tendency towards size reduction. It is suggested that the same may be the case for animals not usually associated with human exploitation, in particular the hyaena. The data from an excavation conducted 40 years ago are inadequate to answer the questions posed by bioarchaeologists today, but the evidence from better known neighbouring sites has subsequently borne out much of what could be proposed here as hypothesis.     

An integrated assessment of archaeobotanical recovery methods in the Neotropical rainforest of northern Belize: flotation and dry screening

This report presents results of a study examining the ancient use of plants at four Late Classic (CE 600-900) Maya rural farmsteads in northwestern Belize. Our research specifically targeted residential middens for macrobotanical recovery. Samples yielded the remains of more than a dozen plant families, representing some genera that do not currently grow in the area. These plants were used in the Late Classic, countering the idea that ancient botanical remains do not survive in Neotropical archaeological contexts. We also evaluated two macrobotanical sample processing methods vis-à-vis one another: flotation and dry screening. Our results indicate that flotation recovered 58% more seeds than dry screening, while dry screening yielded almost twice as much charcoal and other wood as flotation. The divergent quantities in the types of material recovered suggest a comprehensive macrobotanical recovery program should include the use of both processing methods.     

First evidence of Equus asinus L. in the Chalcolithic disputes the Phoenicians as the first to introduce donkeys into the Iberian Peninsula

Two equid species have been documented in the Pleistocene of the Iberian Peninsula, the horse Equus caballus, and the Eurasian hemione Equus hydruntinus. While the former survived the Holocene–Pleistocene until now, the timing for the extinction of the latter is unclear. Scarce, fragmented archaeological remains assess the presence of small equids living in the Holocene of Iberia. Those could possibly correspond to the Eurasian hemione although unambiguous morphological identification is often not possible. With the find of an equid tooth from Leceia, a Chalcolithic fortified site in Portugal, and using both morphological and mitochondrial genome analyses, we demonstrate for the first time the presence of a new equid species in Holocene Iberia, namely a donkey (Equus asinus). Radiocarbon dating of the tooth to Cal 2340–2130, and 2080–2060 BC with 95% probability, demonstrates that donkeys were present in Iberia well before the arrival of Phoenicians in the first quarter of the first millennium BC (900–750 years BC), which were considered so far as the first who introduced donkeys in the region.     

Reconstructing Neolithic groups in Sarawak,Malaysia through lead and strontium isotope analysis

Heavy stable isotope analysis of mid-late Holocene Neolithic burials from Sarawak (Malaysia) identifies groups not apparent in mortuary treatment or inferred subsistence. Isotope ratios of strontium (⁸⁷Sr/⁸⁶Sr) and lead (²⁰⁸Pb/²⁰⁴Pb, ²⁰⁷Pb/²⁰⁴Pb, ²⁰⁶Pb/²⁰⁴Pb) from adult tooth enamel show distinct groups at Niah Cave's West Mouth organized by dietary catchment. Two roughly contemporary sites, Gua Sireh and Lobang Angin, are included to assess regional heterogeneity in northern Borneo. Heavy stable isotope ratios for humans differ from sampled modern plants and archaeological fauna from West Mouth, and suggest a non-local origin for some of the West Mouth human remains. Distinct heavy isotope ratios characterize all three sites and show regional differentiation broadly consistent with geological expectations. Results supplement paleodiet and morphological analyses and have implications for clarifying Niah Cave mortuary use during the mid-late Holocene. Further and more precise geographic placement will follow through additional landscape sampling for strontium and lead isotope values.     

Neolithic subsistence patterns in northern Borneo reconstructed with stable carbon isotopes of enamel

The Neolithic period in island Southeast Asia is characterized by various population movements, technological innovations, and the introduction/adoption of agricultural foodstuffs. Human subsistence trends during this period, however, are poorly understood. Broad spectrum foraging is generally assumed for prehistoric groups utilizing rain forest food resources but the degree to which cultigens were part of the dietary repertoire remains unclear. This paper explores human subsistence patterns at three penecontemporaneous Neolithic sites in Sarawak (East Malaysia) using stable isotope ratios of carbon and oxygen derived from tooth enamel apatite. The sites (Niah Cave, Lubang Angin, and Gua Sireh) differ in local ecology and cultural circumstance but all are situated in C₃-dominant lowland primary rain forest. Significant differences in δ¹³C values between sites likely reflect the canopy effect and variations in foraging pattern. Lower values at Lubang Angin suggest dependence upon closed forest foraging. Higher values at Neolithic Niah Cave and Gua Sireh suggest more open forest horticulture and subsistence, including some form of systematic food production, collection, and/or habitat modification.     

Adaptation and foraging from the Terminal Pleistocene to the Early Holocene: Excavation at Bubog on Ilin Island,Philippines

Abstract

The recently discovered human remains from Callao Cave, northern Luzon, Philippines securely date the migration of hominins into the Philippines to ca. 70 kya (thousands of years ago). The direct route to reach Luzon from the Asian mainland is via Borneo, Palawan, through Mindoro and into Luzon. Our research focuses on Mindoro Island as a potential stepping stone to the main Philippine Archipelago. While Palawan and Luzon have produced evidence for early human occupation, no systematic research on the prehistory of Mindoro has been conducted until now. We report on recent archaeological investigations at the Bubog rockshelter sites on the small island of Ilin just off the coast of Mindoro. The excavations produced evidence of stratified sequences of human habitation at the two rockshelter sites in the form of dense shell middens that date to ca. 11 kya onwards. They provide direct evidence on how variability in landscape formation, sea levels, and landmass during the terminal Pleistocene and early Holocene influenced the behavior of early human populations. Numerous species of molluscs were recorded and provisional results indicate variations in the invertebrate faunas throughout the stratigraphic sequences, resulting from sea level rise and the establishment of coral reefs between Ilin and Mindoro at the end of the Pleistocene. Our results contribute substantially to our understanding of the processes of human island adaptation, complement ongoing research into Island Southeast Asia’s paleogeography, and enhance current knowledge of prehistoric subsistence strategies across the region.     

Pests in an ancient Egyptian harbor

Our investigations combine detailed identification and interpretation of plant remains and associated fauna and their mode of arrival in one of the rock-cut galleries, Cave 3, at the site of Mersa/Wadi Gawasis on Egypt’s Red Sea coast. The site served as a staging area and harbor from which Middle Kingdom pharaohs launched seafaring expeditions to the land of Punt in the early second millennium BC. Quantities of wood, including ship timbers, fastenings, debris related to ship dismantling and reworking, and charcoal were excavated and analyzed. Evidence of marine mollusk infestation (shipworm) was abundant in Cave 3, as were the remains of insect pests of stored foods. We also report on a unique find of a plaster “spill” that preserved the floor of Cave 3 as it was when people worked in the gallery ca. 3800 years ago. The plaster spill created a sealed deposit of plant and insect remains with a diagnostic ceramic fragment, allowing us to securely associate insect remains and “hollow” spikelets of emmer wheat (Triticum dicoccum) recovered from the gallery. An impression of the beetle Trachyderma hispida and its associated exoskeleton fragments provide new evidence of this species as a potential pest not yet reported from an archaeological grain storage site in Egypt. The finding of Tenebroides mauritanicus from the same deposit is the earliest known association of this pest with stored grains. These unique finds shed new light on the risks associated with preserving food supplies, combating pest infestation, and dealing with marine organisms on land and at sea in the pharaonic harbor.     

Rock Hyraxes (Procavia capensis) from Middle Stone Age Levels at Blombos Cave,South Africa

The ～100 ka Middle Stone Age levels at Blombos Cave, southern Cape, South Africa, contain numerous rock hyrax (Procavia capensis) remains. It is often ambiguous to interpret rock hyrax remains from archaeological deposits deriving from cave and shelter sites in southern Africa as the agent or agents of accumulation may be difficult to establish. In this paper, the different taphonomic signatures separating anthropogenic from natural accumulations at Blombos Cave are considered. The analysis indicates that although a few specimens show evidence for raptor and carnivore accumulation, there is also substantial evidence that suggests humans preyed on these small mammals during different times of the year.     

Recognition of post-harvest processing of algarrobo (<Emphasis Type="Italic">Prosopis</Emphasis> spp.) as food from two sites of Northwestern Argentina: an ethnobotanical and experimental approach for desiccated macroremains

Ethnobotanical and experimental approaches were used to: (a) analyse modern Prosopis (algarrobo) food production at the Hualfin valley (Catamarca Province, Argentina) in order to establish food production and processing patterns; and (b) characterise the qualitative and quantitative morphological attributes of the food products and residues that may reach the archaeological record as macrobotanical remains. These approaches were applied to the study of archaeobotanical remains from two archaeological sites from the Argentinean Northwest (Huachichocana and Puente del Diablo). It was concluded that the analysis of Prosopis macrobotanical remains potentially allows the identification of intermediate and final products, by-products and residues of different food/drink preparations. Patay (bread) is the only final product that can be confirmed, but only if the bread itself is recovered. The other algarrobo preparations are jam and beverages and therefore do not leave records. The proportions of fragmented seeds, seeds with fissured testas and endocarps may indicate the production of unrefined and refined flour. Añapa (beverage) and aloja (alcoholic beverage) residues are characterised mainly by a rolling or folding of the epicarp or testa (also by the loosening of the testa). Aloja can be distinguished from añapa only if certain processes, such as the use of hot water and the chewing of the pods, were used, which produced diagnostic characteristics such as thick black patinas on endocarps or heavily twisted fine threads of epicarp fibres. Arrope (syrup) residues are identified by the presence of closed endocarps with thin black patinas and twisted ribbons of epicarp. Flour- and aloja-making were recognised from Huachichocana III contexts and añapa and flour production at Puente del Diablo.     

Palaeoenvironmental and chronological investigations of the Magdalenian sites of Goyet Cave and Trou de Chaleux (Belgium), via stable isotope and radiocarbon analyses of horse skeletal remains

Trou de Chaleux and Goyet are caves situated less than 30 km apart in Belgium that contain stratified Magdalenian artefacts and butchered faunal remains. Published radiocarbon dates suggest that both sites were contemporaneously occupied during to the Late-glacial interstadial. It has previously been suggested that the Trou de Chaleux Late-glacial faunal remains might be slightly older than those at Goyet Cave, and that Trou de Chaleux has two phases of occupation during the Late-glacial interstadial. However, the limited number of radiocarbon dates currently available makes it impossible to determine whether the sites are truly contemporaneous, and the assessment of their absolute chronologies is complicated by a plateau in the calibration curve. In this paper, bone collagen δ¹³C and δ¹⁵N signatures of horse bones from the two sites are used to reconstruct local palaeoenvironments. We hypothesise that if occupations at the two sites were contemporaneous, the horse collagen δ¹³C and δ¹⁵N isotope signatures from both sites will be similar, since comparable carbon and nitrogen isotopic values would reflect similar diets, ecologies and environments. To provide clear dating parameters, new AMS radiocarbon determinations are also presented. Results show that horse collagen δ¹³C and δ¹⁵N isotope signatures at the two sites are different, indicating that the populations were not subject to similar diets, ecologies and environments. The new radiocarbon dates confirm that the horse bones from Trou de Chaleux date to the Late-glacial interstadial, but they also show that in Goyet Cave Horizons 1 and 2, older horse remains dating to ca. 32?000–27?000 ¹⁴C yr BP are mixed with Late-glacial horse remains. The δ¹⁵N values of the Goyet Cave horse bones radiocarbon dated to the Pleniglacial are substantially higher than those that have Late-glacial radiocarbon dates. Therefore, we now hypothesise that the majority of the horse bones isotopically analysed from Goyet Cave Horizon 1 are Pleniglacial in age. Statistical analysis of the radiocarbon dates indicates that the Late-glacial occupation at the two sites was contemporaneous, and that while there may appear to be two phases of occupation at Trou de Chaleux, this may be an artefact of the radiocarbon calibration curve.     

The Holocene Archaeology of Southwest Ethiopia: New Insights from the Kafa Archaeological Project

Abstract  

Southwest Ethiopia’s cool, moist, and steep highlands differ from other African environments, and may have fostered distinct patterns of Holocene resource use and intensification. Prior to 2004, only a few archaeological projects probed eastern and northern margins of this region. The Kafa Archaeological Project (2004–2006) excavated ten caves and rockshelters in different environments in the heart of southwest Ethiopia to obtain a Holocene chronology and compare it with adjacent regions. At Kumali Rockshelter, middle Holocene deposits show use of a microlithic industry to obtain wild game, and excellent macrobotanical preservation promises to reveal changes in plant use from 4,700 ¹⁴C bp to the present. Ceramics and domestic animals appear at Kumali and Koka by ~2,000 ¹⁴C bp, suggesting herding and pottery making appeared late and contacts with neighboring regions were tenuous. Technologically conservative people continued microlith production and sporadic rockshelter use into the eighteenth century CE.     

Early and mid Holocene tool-use and processing of taro (Colocasia esculenta), yam (Dioscorea sp.) and other plants at Kuk Swamp in the highlands of Papua New Guinea

Recent multidisciplinary investigations document an independent emergence of agriculture at Kuk Swamp in the highlands of Papua New Guinea. In this paper we report preliminary usewear analysis and details of prehistoric use of stone tools for processing starchy food and other plants at Kuk Swamp. Morphological diagnostics for starch granules are reported for two potentially significant economic species, taro (Colocasia esculenta) and yam (Dioscorea sp.), following comparisons between prehistoric and botanical reference specimens. Usewear and residue analyses of starch granules indicate that both these species were processed on the wetland margin during the early and mid Holocene. We argue that processing of taro and yam commences by at least 10,200 calibrated years before present (cal BP), although the taro and yam starch granules do not permit us to distinguish between wild or cultivated forms. From at least 6950 to 6440 cal BP the processing of taro, yam and other plants indicates that they are likely to have been integrated into cultivation practices on the wetland edge.     

The Quaternary fossil record of the genus Testudo in the Iberian Peninsula. Archaeological implications and diachronic distribution in the western Mediterranean

This paper explores the presence of tortoise remains and its meaning in Palaeolithic archaeological contexts. We focus on two topics: (1) the presence or absence of the genus Testudo from the Early Pleistocene to the Holocene in SW Europe; and (2) the relationship between Testudo and the palaeoclimatic and palaeoenvironmental conditions diachronically. In order to address this objective, we collected published and unpublished data from different sites on the eastern Iberian Peninsula. The results obtained by this study demonstrate that Testudo hermanni was the only tortoise present in this area until recent times and its presence in archaeological sites is almost always related to anthropic activities. Finally, the disappearance of Testudo from archaeological sites in some areas is related to climatic changes and events that occurred during the last stages of the Pleistocene.     

Evaluating chloroplast DNA in prehistoric Texas coprolites: medicinal,dietary, or ambient ancient DNA?

Molecular analysis of coprolites from Hinds Cave, Texas recovered chloroplast DNA sequences. The sequences were interpreted as evidence of diet. We analyzed 19 Hinds Cave coprolites to evaluate the potential sources of the chloroplast DNA (cpDNA) and compared our results to previous studies. This review shows that some cpDNA sequences could be from well-known prehistoric plants foods. Some other sequences could have come from ambient plant material in the guts of small animals eaten by humans in antiquity. Using pollen concentration analysis, we identify sources of ambient plant material which could have been inhaled or imbibed. It is even possible that cpDNA sequences are from proplastids within ambient pollen grains themselves. However, three sequence types cannot be explained as resulting from only dietary or ambient sources. We suggest instead that these might be from medicinal or hallucinogenic plants. We compared these three sequences to existing sequences in the GenBank. We found that these sequences are 100% matches for Rhamnus, Fouquieria, and Solanum.
