Macrobotanical food remains from a trans-Holocene sequence at Daisy Cave (CA-SMI-261), San Miguel Island, California

Carbonized macrobotanical remains from a trans-Holocene archaeological and paleontological sequence at Daisy Cave provide important insights into the use of food plants by Paleocoastal people as well as later groups on California’s Northern Channel Islands. Small seeds are rare among the macrobotanical remains recovered in the cultural strata at Daisy Cave, which are dominated by charcoal from woody plants used as fuel. The recovery of Brodiaea-type corms from the Early and Late Holocene strata suggests, however, that geophytes were an important source of carbohydrates and calories for Channel Islanders throughout the Holocene. The proposed importance of geophytes is consistent with the abundance of Brodiaea in island vegetation communities recovering from more than a century of overgrazing, as well as the large numbers of digging stick weights found in island sites.     

Building a high-resolution chronology at the Maya archaeological site of El Palmar,Mexico

This paper discusses how detailed analyses of archaeological contexts and macrobotanical remains are critical for building a high-resolution chronology in archaeological research. While the application of Bayesian modelling has improved chronology-building significantly, archaeologists have sometimes neglected different dates recovered from the same depositional layer without further scrutiny. Based on 78 radiocarbon samples, this problem is challenged by building a high-resolution chronology of the Guzmán Group, a small plaza compound of the ancient Maya city of El Palmar, Mexico. The results permit a deeper understanding of relationships between dynastic interactions and the emergence of non-royal elites in Classic Maya society.     

From Crafting to Caching: Technological and Iconographic Analyses of Blue Creek Cache 37

This paper presents technological and iconographic analyses of a Late Classic (a.d. 600–830) lithics cache recovered from the ancient Maya site of Blue Creek, Belize. The cache consisted of 21 obsidian prismatic blades and a number of chert artifacts, including 21 stemmed bifaces, a large laurel leaf biface, and a tridentate eccentric. The technological analysis of the stemmed bifaces identified three distinct stem production techniques that may be attributable to a combination of idiosyncratic knapping gestures and laterality, or handedness. A survey of Maya iconography demonstrated that large laurel-leaf bifaces and tridentate eccentrics occur in scenes depicting sacrifice and the burning of human remains, often by ritual specialists titled ch’ajoom, or “person of incense.” It is suggested that the presence of a large laurel-leaf biface and tridentate eccentric in the cache may indicate that Blue Creek was the residence of ch’ajoom at some point during the Late Classic period.     

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.     

Perspectives on ancient Maya bone crafting from a Classic period bone-artifact manufacturing assemblage

This paper explores the nature of utilitarian bone-artifact crafting from the perspective of an unusual assemblage of manufacturing debitage dated to the Terminal Classic. This large assemblage contains unprecedented quantities of debris from the production of utilitarian artifacts, primarily bone perforators (needles, pins, awls). The collection was recovered from Group L4-3, a small, non-elite, Late and Terminal Classic residential complex located adjacent to the central palaces and residences of the ruling nobility of the ancient Maya site of Dos Pilas, Petexbatún, Guatemala. This study evaluates the standardization of raw materials, methods, and finished artifacts of the assemblage based on criteria used in discussions of scale of production and craft specialization. These evaluations are used to explore whether the L4-3 bone crafters were part- or full-time specialists, whether they produced their products on a large or a small scale and for domestic or external consumption, and for whom they crafted these products. The continuous occupation of the L4-3 complex through the transition from Late to Terminal Classic, a time of social change, offers a rich background for this evaluation of Maya utilitarian bone-artifact crafting.     

COMPUTED TOMOGRAPHY AND COMPUTED RADIOGRAPHY OF LATE BRONZE AGE CREMATION URNS FROM DENMARK: AN INTERDISCIPLINARY ATTEMPT TO DEVELOP METHODS APPLIED IN BIOARCHAEOLOGICAL CREMATION RESEARCH

To improve the methods used to study prehistoric cremation rituals, cremation urns from the Danish Late Bronze Age were examined using computed tomography and computed radiography (digital X‐ray). During micro‐excavation, the digital images were used as a registration tool. Our results suggest that osteological ageing and sexing are more accurate when combining CT images with excavated remains. Digital volume rendering further enables a compromised estimation of the original cremation weight. Micro‐excavation is clearly a primary cause of bone fragmentation. Cremated remains affected by lower cremation intensity show markedly poorer preservation and recovery than do white calcined fragments. Thus post‐excavation estimations of cremation intensity are systematically biased.     

Evidence for Maya Household Subsistence and Domestic Activities: Use-Wear Analysis of the Chipped Chert Assemblage from Pook’s Hill,Belize

Abstract

From 1999–2005, the Belize Valley Archaeological Reconnaissance Project excavated Pook’s Hill (PKH-1), a single plazuela group located in the Roaring Creek Valley, Cayo District, Belize. Artifacts recovered at Pook’s Hill date predominantly to the Late and Terminal Classic (A.D. 700–950) and can be stratigraphically segregated into two distinct occupation phases, namely a Late Classic (A.D. 700–830) and a Terminal Classic-Early Postclassic (A.D. 830–9507+) phase. The chipped chert and chalcedony tools from the two phases were included in a combined program of low- and high-power use-wear analysis to reconstruct aspects of the socioeconomy. The results of the analyses reveal that the site’s inhabitants produced and used both formal and informal tools for a wide variety of subsistence and domestic tasks, and for the production of some utilitarian items. Stone tool use-wear evidence and the recovery of small quantities of other artifacts suggest that the Maya from Pook’s Hill produced more valuable objects of bone, stone, and shell, although it is difficult to accurately identify craft-production activities at the site from the context of recovery. Despite some variation in the specific activities undertaken with the chipped stone tools over time, the organization of lithic technology at Pook’s Hill did not change significantly from the Late Classic into the Early Postclassic period.     

Phytolith taphonomy: a comparison of dry ashing and acid extraction on the breakdown of conjoined phytoliths formed in Triticum durum

Durum wheat plants grown under optimum irrigation conditions in Jordan were processed in three different ways: 1) using a dry ashing method, 2) using acid extraction and 3) using both these methods, first dry ashing and then acid extraction. The aim was to determine if the laboratory processing method employed has an impact on the number of conjoined phytoliths recovered. This is important because it has been proposed that the number of conjoined phytoliths, or multi cells, can be an indication of water availability in arid and semi-arid regions (Rosen and Weiner 1994). The results showed that the processing method does have an impact on the resulting assemblage, with dry ashing producing a greater number of multi-cells than acid extraction. It is proposed that either the more violent oxidation of organic matter during acid extraction causes the breakup of conjoined phytoliths, or that the silica dehydrates during dry ashing resulting in a slight fusion between the individual phytoliths and hence more conjoined forms.     

Flotation versus dry sieving archaeobotanical remains: A case history from the Middle Horizon southern coast of Peru

Abstract

During excavations at the site of Casa Vieja located in the Peruvian coastal desert, archaeological plant remains were systematically collected to assess whether it is more productive and informative to sieve sandy sediments in dry environments or to process such samples by water flotation, a persistent methodological concern. At Casa Vieja, dual subsamples were collected and analyzed using both of these procedures. For dry, sandy sediment conditions, each processing strategy was found to yield a different view of the botanical remains. Dry sieving recovers more of the larger plant specimens whereas water flotation yields more of the smaller-sized material. These results should be incorporated into archaeological research designs in the future, especially for desert environments.     

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.     

Water Separation and Flotation Processes

Abstract

The water separator, a mechanical flotation device which is finding increasing usage among Mediterranean archaeologists, is compared with “tub” flotation which is widely practiced by North American archaeologists. The water separator was found to be two to three times more efficient than tub flotation. A redesigned separator is presented which should further improve this figure.

The problem of sample size and the attendant aspects of representativeness are evaluated by a comparison of items of various classes recovered in a 100% separator sample compared to the much smaller tub flotation sample.

Finally, the specific biasing effects of various recovery techniques with particular emphasis on fish remains is discussed.     

Recent Research in Paleoethnobotany

This article discusses paleoethnobotanical research and results presented in the recent literature. Although archaeobotany is a fairly recent addition to the study of the past, it now encompasses a diverse range of techniques, analyses, and new results. Issues that are prominent in this archaeological subdiscipline include the origins of agriculture, resource use, environmental reconstruction, anthropogenic environmental change, political-economic change, plant cultivation and crop production, plant processing, consumption (diet), and site deposition. Some of the plant identification methods for macrobotanical remains include morphology using light microscopes, histology with the scanning electron microscope, and statistics. The study of microbotanical remains has expanded greatly and now includes pollen, phytolith, chemical, and molecular analyses.     

High-Altitude Agro-Pastoralism in the Kyrgyz Tien Shan: New Excavations of the Chap Farmstead (1065–825 cal b.c.)

ABSTRACT

The highlands of Central Asia posed considerable challenges to early agriculturalists, yet the processes of human subsistence strategies there remain poorly understood. In this paper, we present results from the excavation of the Chap in Kyrgyzstan. The recovery of a rich macrobotanical assemblage consisting of several crop species and crop processing debris, together with skeletal remains of pastoral livestock, indicate a localized agro-pastoral complex at 2000 masl dating to 1065–825 cal b.c. Aerial photogrammetry, magnetometry, and topographic modeling reveal local irrigation systems, while stone artifacts are linked with cultivation and crop processing. Furthermore, the ceramic assemblage reveals a local production tradition and stylistic similarities with communities of neighboring regions. Overall, data from Chap contribute to a new understanding of human ecology and agricultural development in the mountains of Central Asia, suggesting that domesticated plants and animals were integral for the intensive occupation of high-elevation valleys in Central Asia.     

Miliacin in palaeosols from an Early Iron Age in Ukraine reveal in situ cultivation of broomcorn millet

During the archaeobotanical investigation of Scythian–Sarmatian period (Early Iron Age), pits with crop processing waste, discovered in the floodplain of Donets River, eastern Ukraine, and charred remains of cereal grains, dominated by broomcorn millet, were recorded. The grains from the pits were radiocarbon dated to the fifth to first century BC. Those pits are distant from any known contemporaneous settlement. The apparent disconnection of these pits from any local settlement suggests that (1) millet was brought from other locations by mobile groups, or (2) millet was cultivated locally by populations whose settlements have left no discernible archaeological trace. The analysis of molecular biomarkers preserved in palaeosols that are stratigraphically connected to the pits revealed high levels of miliacin, a molecule that can be preserved in ancient soils and sediments, and that is consistent with broomcorn millet (Panicum miliaceum). High levels in miliacin in soils stratigraphically connected to the pits are interpreted as the result of a large biomass of P. miliaceum produced at time of soil formation. Our biogeochemical results applied to a palaeosol thus attest to the in situ cultivation of crops dominated by the broomcorn millet during the early Iron Age in the floodplain of Donets River. Biochemical examination of soils and palaeosols can thus provide useful information on past dynamics of land-use by ancient population, especially when settlements or macrobotanical remains are absent.     

Let no space go to waste: comparing the uses of space between two Late Classic centers in the El Paraíso valley,Copan, Honduras

Phosphorus analysis of earthen and plaster floors has been used in Mesoamerica to locate and identify activities at ancient sites. This study uses phosphorus analysis to discern if the inhabitants of two Late Classic coeval and proximal sites located in the El Paraíso Valley of Honduras were different culturally from each other. The buried earthen and plaster surfaces of both sites were systematically sampled and analyzed for phosphorus remains. The patterns of elevated phosphorus from these open spaces were subsequently compared to determine if differences in the habitual use and treatment of open spaces could be discerned. These differences are evaluated as a function of behavioral norms, functional responses, and cultural dispositions in order to evaluate the extent to which these two populations were indeed different from each other.     

Last Meals: Recovering Abdominal Contents From Skeletonized Remains

Excavation and analysis of human remains is becoming a polarized field in anthropology; it is therefore necessary to consider alternate avenues of data collection from these features to maximize their potential. The analysis of abdominal soils for digestive tract contents is consistently overlooked in research designs. Two previous studies have attempted to recover abdominal contents through systematic sampling methods using multiple inhumations and two others have recovered colon contents in isolated instances. This research briefly familiarizes the reader with current state of investigation, and then proposes and tests a different method to recover abdominal contents in skeletonized inhumations. Using this method, more than 70% of the sampled inhumations yielded data on ingested botanical products. Though recovered, faunal remains were rare. The implications of recovery, some interpretations for each population, and avenues of future research are considered.

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.     

Collective Remembering in Archaeology: a Relational Approach to Ancient Maya Memory

Drawing on a case study from the Maya site of Actuncan, Belize, this article presents collective remembering as a way to conceptualize the relational construction of memory by ancient societies. Emphasizing the process of remembering allows archaeologists to investigate how memory divides as well as unites. Over time, the interactions between humans and between humans and their landscape that take place as part of everyday life produce memories of the past that are inaccurate and inconsistent between individuals. In particular, people who interact frequently, either due to geographic proximity or similarity in socioeconomic status, tend to form mnemonic communities—communities based on a similar understanding of the past—that may serve as identity markers differentiating them from other groups. At Actuncan, the community’s past was collectively remembered across times of prosperity and subjugation. First, the site was a Late and Terminal Preclassic seat of an early divine king who built a monumental ceremonial center. Second, when the site was subjugated during the Early and Late Classic periods, the ceremonial center fell out of use, but the site’s commoner households remained continuously occupied. Finally, in the Terminal Classic period, the site’s residents reestablished Actuncan as a local seat of authority following the Classic Maya collapse. The community’s use of the Preclassic monumental core during the Terminal Classic period indicates that the memory of the site’s Preclassic apogee served to legitimize their Terminal Classic authority. However, the Preclassic past was remembered in a manner consistent with contemporaneous cultural forms and the site’s recent past of subjugation.     

Tikal timbers and temples: ancient Maya agroforestry and the end of time

Tikal, a major lowland Maya civic-ceremonial center in the heart of the Petén region of Central America, relied heavily on the adjacent lowland rainforest as a resource base for fuel and construction materials. In this study, we analyzed 135 wood samples from timbers used in the construction of all six of the city's major temples as well as two major palaces to determine which tree species were being exploited and to better understand ancient Maya agroforestry practices during the Late Classic period. We found evidence for a change in preference from the large-growing, upland forest species, Manilkara zapota, to a seasonal wetland species Haematoxylon campechianum in A.D. 741 as well as a decrease in lintel beam widths over time. Though M. zapota later returned as the wood species of choice in A.D. 810, beam widths were found to be significantly smaller. These findings concur with models that hypothesize widespread deforestation during the Late Classic period and indicate a declining forest resource base by the 9th century A.D. Because of the many large timbers available for temple construction in the 8th century, some system of forest conservation is indicated for the ancient Maya prior to the Late Classic period.
