What goes in does not always come out: The impact of the ruminant digestive system of sheep on plant material,and its importance for the interpretation of dung-derived archaeobotanical assemblages

Abstract

On archaeological sites where livestock dung was a major fuel source, plant material that survives digestion intact may well be preserved in the remnants of dung-fuelled fires. Preserved plant remains which were derived from dung relate to the diet of animals, and thus provide a way of investigating the agro-pastoral economies of the past. In order to improve our understanding of the taphonomic processes to which plant material is exposed to during digestion, we applied archaeobotanical methods to the analysis of dung from sheep fed a known diet of cereal and wild plant material. Two clear patterns emerge from these investigations. First, cereal material (grain or chaff) survives digestion poorly and was rarely found in the dung analysed. Second, large proportions of seeds of various wild species survive digestion in an identifiable form, probably due to their small size and/or protective coating. These findings are crucial for reliable interpretation of dung-derived plant material in archaeological settings.     

Identifying Threshing Floors in the Archaeological Record: A Test Case at Iron Age Tel Megiddo,Israel

Abstract

The identification of activity areas in archaeological sites is an important part of archaeological research contributing to the reconstruction of past ways of life. The threshing floor is an activity area that relates to subsistence practices in agricultural societies, yet identifying threshing floors in the archaeological record is difficult. We present a geoarchaeological study conducted at an Iron Age layered feature unearthed in 1998 at Tel Megiddo, Israel, in which we tested a previous assumption that it represents the remains of a threshing floor. Using micromorphology, mineralogy, elemental analysis, phytoliths, and dung spherulites, we show that the materials comprising the bulk of the layers in the Megiddo feature include large amounts of wood ash and the inorganic remains of livestock dung. Based on these results, coupled with ethnographic data on threshing floors and observations on the macroscopic traits of the feature under consideration, we conclude that the layered feature at Megiddo does not represent a threshing floor but a single-household trash heap. We suggest that the interpretation of similar features at other archaeological sites as threshing floors be reevaluated.     

Herbivorous livestock dung: formation,taphonomy, methods for identification,and archaeological significance

Herbivore livestock dung has been identified in archaeological sites around the world. Focusing on dung from the ubiquitous Old World herbivorous domesticates – sheep, goats and cattle – this review deals with the materials found within dung that have relevance to archaeology. The natural and anthropogenic/cultural taphonomic processes that affect the preservation and identification of livestock dung, and the archaeological information that can be extracted through detailed studies of the context and content of identified livestock dung in archaeological sites is modeled and discussed.     

Geoarchaeology in an urban context: The uses of space in a Phoenician monumental building at Tel Dor (Israel)

Interpretation of past urban societies in the Near East, whose settlements are known mostly as tell sites, is largely based on macro-stratigraphy and on the association of architecture with macroscopic artifacts. Analyses of sediments, common in prehistoric sites, are rare in tell sites. Here we show the results of a detailed geoarchaeological study of the micro-stratigraphy of a sedimentary sequence associated with early Iron Age Phoenician monumental architecture. The study involves mineralogical, micromorphological and phytolith analyses and provides new insights into the stratigraphic sequence and the use of architectural spaces. The sedimentary sequence examined comprises alternating layers of gray ‘fill’ deposits and white ‘floors’. We show that ‘floors’ made from local calcareous sandstone in the lower part of the sedimentary sequence were heated and are thus in effect ‘plaster floors’. A concentration of micro-laminated, trampled fish remains above the most elaborate of these plaster ‘floors’ indicates activities related to fish processing. Fine white layers in the upper part of the sedimentary sequence that were considered as plaster based on macroscopic examination are in fact composed almost entirely of opaline grass phytoliths. The phytoliths appear in an undulating micro-laminated structure and are associated with dung spherulites and phosphate nodules, thus probably reflecting livestock penning. The formation of ‘phytolith floors’ involves extensive volume reduction due to the degradation of the organic material and this may result in ‘floor’ subsidence, a phenomenon that is often observed in archaeological sites. Most ‘fill’ deposits include macroscopic and microscopic remains of wood ash, bones, phytoliths, charcoal, ceramics, plaster and mollusk shells, reflecting the debris produced from household activities. This study shows how a combination of macro-stratigraphy with microscopic and mineralogical analyses of the sediments within architectural spaces can provide information on the varying ways in which the space was used through time, and also contributes to solving macro-stratigraphic problems.     

Identification of pastoral sites using stable nitrogen and carbon isotopes from bulk sediment samples: a case study in modern and archaeological pastoral settlements in Kenya

The identification of pastoral sites in the East African archaeological record is problematic. Recently, a method for the identification of degraded livestock enclosure sediments had been developed that takes into account the geoarchaeological indicators of micromorphology, phytolith concentrations and the mineral assemblages. This suite of indicators may not always be present in degraded livestock enclosure sediments. This study presents an additional indicator by which degraded livestock enclosure sediments may be identified, namely the isotopic composition of organic nitrogen measured on bulk sediment samples. We studied a highly controlled ethnoarchaeological sequence of abandoned Maasai livestock enclosure sediments sampled in Rombo area, southern Kenya. The results were compared to archaeological sediments from the Elmenteitan Pastoral Neolithic site of Sugenya, southwestern Kenya, radiocarbon dated to ca. 2000 BP (uncalibrated). The sediments from both sites were studied using all four types of analyses, i.e., micromorphology, mineralogy, phytolith concentrations, and stable carbon and nitrogen isotopic compositions on bulk sediment samples. The results show that in abandoned livestock enclosure sediments of known ages a significant enrichment in the heavy nitrogen isotope (¹⁵N) occurs, and that carbon isotopic compositions may be useful for differentiating cattle from caprine enclosures following their dietary preferences (i.e., grazers vs. browsers). A similar pattern of ¹⁵N enrichment is observed in sediments sampled within the site of Sugenya while sediments sampled outside the site's perimeter are generally depleted in ¹⁵N. The micromorphological, mineralogical and phytolith analyses support the conclusion that the sediments from within the site of Sugenya represent degraded livestock enclosure sediments. The carbon isotopic composition from the degraded dung deposits strongly suggests that livestock kept at Sugenya were cattle. Overall, this study presents new empirical data that can be used for the identification of livestock enclosures, and shows that the isotopic signatures and geoarchaeological indicators can preserve for at least two millennia.     

Phytolith-rich layers from the Late Bronze and Iron Ages at Tel Dor (Israel): mode of formation and archaeological significance

The presence of many phytolith-rich layers in late Bronze and Iron Age deposits at Tel Dor, Israel, are indicative of specific locations where plants were concentrated. Detailed studies of six of these phytolith-rich layers and associated sediments from Tel Dor show that the phytoliths were derived mainly from wild and domestic grasses. The most common domestic grass was the cereal Triticum aestivum (bread wheat). Three of these layers have a microlaminated microstructure, associated dung spherulites and phosphate nodules; characteristics that all point to the phytolith-rich layers having formed from dung in animal enclosures. In two of the layers, the microlaminated structure is absent while dung spherulites and phosphate nodules are present, suggesting that these too originate from dung that was not deposited in an enclosure. The sixth layer is microlaminated but does not contain spherulites. We thus cannot suggest a parsimonious explanation of its observed properties. Concentrations of burnt phytoliths are present in three locations, implying that dung was either burnt in situ or the ashes from burnt dung were redeposited. The transformation of dung accumulations into phytolith-rich layers involves a loss of organic material and hence a significant reduction in sediment volume, which is clearly apparent in the stratigraphy of some of the locations examined. The volume reduction can be observed in the macrostratigraphy and has important implications with regard to macrostratigraphic interpretation. The presence of abundant phytolith-rich layers on the tell has significant implications for the concept of ‘urbanism’ during these periods.     

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.     

Agricultural and household activities in Vestfold,Southeast Norway,as illustrated by pollen data and the charred remains of crops and wild plants

This paper presents and interprets two data sets from Vestfold, Southeast Norway: the pollen record is from a small lake basin, isolated from the sea in Mid Mesolithic (8100–6400 cal BC), and with a record of sediment deposition up to recent time. Charred plant remains from six settlement sites ranging in date from the Late Neolithic (2400–1800 cal BC) to the Merovingian Period (cal AD 570–800). Soil from archaeological contexts that was recovered from several prehistoric settlement features (two- and three-aisled houses, a rock shelter and a pit) has also been investigated. The number and concentrations of identifiable charred macro remains are low from all features except one, but the records contribute to the interpretation of agriculture and wild plant use. Carbonised cereals dated to the Late Neolithic/Early Bronze Age are reported from a two-aisled house. Naked barley was the main cereal identified and a few weed seeds were found with the cereal grains. In a rock shelter nearby, cereals and seeds of flax were found, demonstrating cultivation in the Late Bronze Age. Pollen of ribwort plantain recorded in lake deposits in Nordbytjern, 0·5?km to the southwest, also indicates agricultural activity in the southern part of Vestfold during the Late Bronze Age. Archaeobotanical samples from Early Iron Age houses contained low concentrations of carbonised cereal remains, mainly hulled barley, but also wheat and oat. Seeds/fruits of weeds, plants of moist/wet habitats and grasses increase in abundance from the end of Roman Period. The high concentration of hulled barley found in a pit at the site of Ringdal 13 confirms that hulled barley was a cereal used in the Iron Age. Throughout the Iron Age, cereal pollen has a continuous curve in the Nordbytjern pollen diagram, demonstrating the significance of cereal cultivation in Vestfold. Flax was also cultivated in the vicinity of and probably processed in Nordbytjern. Large numbers of rush seeds and sedge nutlets indicate a possible involvement in basketry and cordage making and/or as animal fodder.

A DOG’S LIFE IN THE IRON AGE OF THE SOUTHERN LEVANT: CONNECTING THE TEXTUAL AND ARCHAEOLOGICAL EVIDENCE

Studies of dog remains focused on the Iron Age southern Levant generally highlight their unique nature in the archaeological context, specifically in relation to their post-mortem exploitation. Here we review the published archaeological and textual data to evaluate the current understanding of dogs’ roles in their Iron Age settings. The analysis reveals that dogs are relatively common in the archaeological record, having been reported at 66% of sites. This study further contextualizes this presence in light of their co-occurrence with caprine and wild taxa. The significant number of dog remains indicates that they were part of the social matrix of a village. While dogs have been viewed as ‘unclean’ or pariah, based on certain textual references in the Hebrew Bible, we assert, on the basis of the archaeological record, that they were part of the life of the village, functioning as herders, guards and occasionally hunters.     

The Medieval Manor of Penhallam,Jacobstow, Cornwall

THE remains of the medieval manor of Penhallam lie in a sheltered valley in the parish of Jacobstow, some 3 miles from the sea. It was one of the principal houses of the Cardinham family who held, under the king, the largest seignory in the county of Cornwall. Extensive excavation between the years 1968 and 1973 revealed substantial remains of a sophisticated manor house, standing within an earlier ring-work. The stone-built house was constructed in four periods during the late 12th and early 13th centuries. It was deserted in the middle of the 14th century and was gradually demolished. Mo remains of the buildings were visible above ground at the time of the commencement of the excavation. The site, now known as Berry Court, takes the name of a small homestead of probable 16th-century origin, standing on the outer edge of the moat.

There was no visible trace of the hall associated with the early Norman ring-work, but its existence is attested by the subsequent development of the site. Excavation revealed that there were stone buildings standing on the four sides of a courtyard. They comprised a hall, camera, chapel, service rooms, lodgings and a gatehouse. From these remains it was possible to obtain much information about the construction and development of a medieval manor house in the 12th and 13th centuries. Excavation of the 13th-century gatehouse and drawbridge well revealed the construction, assembly and operation of a counter-balanced bridge.

The excavation finds, attributed to the 13th and early 14th centuries, have been presented to the Royal Institution of Cornwall at Truro.     

Insights into Past Ritual Practice at Yikpabongo, Northern Region, Ghana

Varied interpretations have been provided for the figurine mound sites located in Koma Land and in the Mogduri District, Northern Region, Ghana, including that they represent burial mounds or shrines. In particular, the producers or affiliates of the mounds are unknown, as the traditions of the present inhabitants of the archaeological region dissociate themselves from the mounds. Current excavations of the mounds have provided considerable contextual information, leading the excavation team to hypothesise that the mounds are best understood within a shrine context and that the figurines, possibly representing ancestors or other beings, were used in ceremonies aimed at communicating with the supernatural world for healing or other purposes. This article presents the current understanding of these mound sites with particular reference to the 2010 and 2011 excavation seasons and the ethnography of existing groups in the area. Possible future avenues of enquiry are also discussed.     

Interpretative scenarios emerging from plant micro- and macroremains in the Iron Age site of Salut,Sultanate of Oman

The archaeobotanical research carried out in the Iron Age site of Salut (north Oman) gives insights on various interpretative scenarios: the ancient vegetation surrounding the site, oasis farming, and possible ritual practices. The landscape was dominated by dry shrublands with, among others, acacia, jujube and tamarisk that were exploited for obtaining timber and firewood. Agricultural practices mainly consisted of date palm, cereal and sesame cultivation. By comparing the datasets it was possible to assess that the date palm had various uses in this site: one hypothesis involves its offering in ceremonial practices. This third scenario suggests a new way of interpreting some of the plant remains in an archaeological site as Salut, a multipurpose site including a possibly cultic function.     

Cultivation History Beyond the Periphery: Early Agriculture in the North European Boreal Forest

We have investigated the environmental history of human occupation and the development of agriculture in the eastern interior Lake District of Finland. The material consists of archaeological data, which is reviewed in topographical and agrogeological context, and pollen analytical evidence of agricultural indices from eight precisely dated (varved) lake sediment sequences. Before the Viking Age, archaeological evidence, consisting of stray finds, dwelling sites, and graves, is very scarce. Iron Age finds are clearly confined to the lowland environs with silty and clayey soils. During the Viking Age, the number of stray finds multiplies and the first cemeteries are established. Comparison between Viking and Crusade Period finds reveals a topographic shift toward higher locations and morainic soils. Most of the cup-stones are located on upland sites—that is, not in connection with known Iron Age sites. These are interpreted as medieval indicators of slash-and-burn farming of the fertile but stony supraaquatic morainic soils. There is pollen analytical evidence of sporadic cultivation in the area from the Bronze Age onward. Afterca. AD 700, the occurrence of cereal pollen grains becomes regular but remains discontinuous at each site until after the turn of the millennium. There is then an exponential rise in the cereal pollen rain, indicating a fully agricultural population.     

Precolumbian Settlements on Carriacou,West Indies

Abstract

The first systematic archaeological investigation of Precolumbian sites on the island of Carriacou in the West Indies provides a rich source of information regarding Amerindian settlement in the southern Caribbean. Herein, we report results from an island-wide survey and subsequent excavation at two large village sites—Grand Bay and Sabazan—that provide evidence for an intensive late Ceramic Age occupation dating between CAL. A.D. 400–1200. Results from four seasons of excavation at Grand Bay and two at Sabazan indicate that inhabitants colonized the island later than larger nearby islands (although an earlier settlement is possible); were engaged in inter-island and South American interactions as evidenced through analysis of pottery, stylistic artifacts, and faunal remains; exploited a variety of marine and terrestrial foods, including several animals rarely found in the Antilles that were translocated to the island from elsewhere; and buried their dead in and around shell middens and, at least once, under a habitable structure.     

Archaeobotanical inference of Bronze Age land use and land cover in the eastern Mediterranean

Charcoal and charred seeds at five Bronze Age archaeological sites discern ancient land use in the eastern Mediterranean. Seed frequencies of orchard crops, annual cereals and pulses, and wild or weedy plants are used to characterize plant utilization at different archaeological sites on the island of Cyprus, in the Rift Valley of Jordan, and in the Jabbul Plain and along the upper Euphrates River valley in Syria. Seed to charcoal ratios provide proxies to determine the relative usage of dung versus wood for fuel across the ancient Mediterranean landscape. Greater charcoal and lower charred seed values are interpreted to represent a wooded environment, while higher amounts of charred seeds and minimal wood charcoal suggest a much great use of dung as a fuel source. Interestingly, Politiko-Troullia (Cyprus, Cypriot archaeological sites are, by convention, named for the nearest modern village (Politiko), followed by an italicized toponym (Troullia) referring to the plot of land that incorporates the site) has the lowest seed to charcoal ratio, suggesting its residents primarily burned wood and that the landscape surrounding Troullia remained relatively wooded during the Bronze Age. In contrast, villagers at Tell el-Hayyat (Jordan) utilized a mixture of wood and dung, in contrast to Tell Abu en-Ni’aj (Jordan), and especially Umm el-Marra and Tell es-Sweyhat (Syria), where inhabitants relied solely on dung fuel. Comparative analysis and interpretation of seed and charcoal evidence thus illustrates the variety of fuel use strategies necessitated by the dynamic and diverse Bronze Age landscapes of the Eastern Mediterranean.     

An Ethnoarchaeological Case Study of Dung Fungal Spore and Faecal Spherulite Taphonomy in a Pastoral Cave Deposit

ABSTRACT

In alkaline cave sediments, the presence of faecal spherulites is regarded as a reliable indicator of animal dung. Spores of coprophilous fungi are nowadays frequently employed as grazing indicators in palaeoecological sequences, but their use in dryland pastoral deposits is not routine in geoarchaeological practice. The paper assesses the relationship between the occurrence of spherulites and dung fungal spores from an abandoned rock shelter used as a stable for several decades. A clear match between these proxies is shown, and their distribution across the sediments is discussed, highlighting the potential of coprophilous spore analysis from archaeological stabling deposits, alongside other established dung indicators. The abundance of other microfossils (parasite eggs, coccolith plates and freshwater indicators) is also quantified and discussed.

Surplus Production and Marine Resource Use in the North Norwegian Iron Age

The coast of northern Norway was an important dried‐cod production area during the Medieval period. During the Iron Age, marine resources had also played a vital role in the economy of the inhabitants in the region. The increase in marine harvesting post c.AD 600, as substantiated by archaeological finds, suggests that mass maritime goods, in addition to those goods of a prestigious character, were a significant part of the chiefly provisioning system of the Iron Age.
