However, previous studies on pyrotechnological installations, such as pottery kilns, pertaining to this period, have often been mainly descriptive, with a limited use of archaeometric investigations. This work presents a multi-method investigation of a Chalcolithic kiln recently discovered in the Bora Plain (part of the larger Peshdar Plain, in Iraqi Kurdistan), which combines stratigraphic analysis, pyrotechnological, micromorphological, and micro-remains analyses.

Appearing from around 1200 CE, and showing considerable variability in size and form, these settlements are named after the dry-stone wall structures that characterize them. Stone Walled Sites were occupied by various Bantu-speaking agropastoral communities. In this paper we test the use of pXRF (portable X-ray fluorescence analysis) to generate a 'supplementary' archaeological record where evident stratigraphy is lacking, survey conditions may be uneven, and excavations limited, due to the overall site size. We propose herein the application of portable X-ray fluorescence analysis (pXRF) coupled with multivariate exploratory analysis and geostatistical modelling at Seoke, a southern African SWS of historical age (18 th century CE). The aim of the paper is twofold: to explore the potential of the application of a low cost, quick, and minimally invasive technique to detect chemical markers in anthropogenic sediments from a Stone Walled Site, and to propose a way to analyse the results in order to improve our understanding of the use of space at nongeneralized scales in such sites.

Here, a coprolite (fossilized feces) from the 1.2-million-year-old paleontological site of Haro River Quarry in northwestern Pakistan was analyzed for paleoparasites. Micromorphological thin sectioning and Fourier-Transform Infrared Spectrometry (FTIR) analysis confirms the coprolite belonged to a bone-eating carnivore, likely the extinct giant short-faced hyena (Pachycrocuta brevirostris). Parasitological analysis shows the coprolite to be positive for Toxocara sp. To our knowledge, this is the earliest evidence for Toxocara sp. found.

Archaeological cooking installations are primarily identified using analogy of shape and size to ethnographic installations. The study pre-sented here establishes direct evidence to the use of fire within mud constructed cooking installations, thus providing means for reducing ambiguity in identification of archaeological cooking installations. In addition, we present here a newly developed method that enables a clear-cut distinction between wood and dung ashes used as fuel materials in many modern and archaeological domestic contexts. The study is based on an ethnoarchaeological research in rural households at the Republic of Uzbekistan that was followed by geoarchaeological analyses of installation walls, wood ash, dung ash and wood and dung standards collected in the study area. Field work included ethnographic observations, interviews with informants and temperature measurements during cooking experiments. We show that changes in the clay mineral structure due to exposure to high temperatures on the interior walls of cooking installations can be detected using FTIR (Fourier Transform Infrared) spectroscopy, providing for the first time direct evidence to the use of fire within such installations. We demonstrate that the temperature recorded by clay alteration on installation walls as well as in the ashes left on installation bottoms does not corre-spond to baking or cooking temperatures. We also show that the newly developed method, based on the ratio of wood ash pseudomorphs to dung spherulites, separates between wood and dung ashes with very high certainty. Yet, we identify a range of values where differentiation between wood and dung ashes is uncertain, and suggest it results from intensive mixing processes. Lastly, we show that phytolith mor-photype analysis is an insufficient tool, if used alone, for distinguishing wood from dung ashes in the study area. The newly developed tools for temperature estimation within mud constructed installations and for fuel origin determination contribute to better understanding of cooking-related practices, and can be applied to archaeological contexts worldwide.

A cooking installation termed the Philistine pebble hearth is associated with the arrival of the Philistines at the beginning of the Iron Age in the southern Levant (ca. early/mid-12th century B.C.). These installations have been studied using traditional methods, focusing on a description of form and style in relation to the pottery of the period. Here we present a study using an experimental approach. We prepared three sets of experimental pebble hearths to study the pebbles' thermal behavior in relation to their volume. The comparison of these results with observations of Iron Age I archaeological hearths reveals different patterns in pebble shattering and soot patterns, indicating that the archaeological hearths were used in a different manner than the experimental ones. The experiments highlight the utility of shattered pebbles as an indicator of the use of fire directly on Philistine hearths, even in the absence of ash and/or charcoal. They also demonstrate that these installations may have been used with open fire or live embers. The results are applicable to the study of hearths worldwide, with implications for appropriate excavation methods and basic identification of ancient pyrotechnologies.

The former is found in large quantities in wood ash and the latter in animal dung. In this chapter, we describe the formation and composition of these micro-remains and discuss their significance for archaeological interpretation. Additionally, we describe the methods used for their extraction from archaeological deposits, identification using a polarized light microscope and quantification. Finally, we highlight their preservation potential and discuss taphonomic processes that may result in misidentification and/or impaired archaeological interpretation.

Thirteen circular pebble installations were found scattered throughout a residential neighbourhood dating to the Early Bronze Age III at Tell es-Safi/Gath. Five such installations were recently studied by implementing an integrated micro-archaeological approach by which all micro- and macro-artefacts were analysed using various analytical techniques. Based on the analysis of ash-micro remains identified in the sediments, associated plant remains, flint and pottery, we suggest that these installations were used for food-processing, cooking and/or other domestic low-heat tasks. The installations first appear at Tell es-Safi/Gath during the Early Bronze Age III, and seem to disappear during later periods. The functional roles of these installations are discussed in comparison to finds from other Early Bronze Age sites, and of other food preparation traditions known from other periods and cultures.

Sediment samples from two newly excavated areas at the rear and entrance of the cave were analysed using infrared spectroscopy, micromorphology and phytolith analysis and dated through uranium-thorium and luminescence techniques. The rear of the cave shows carnivore activity and low artefact concentrations. It also exhibits a shift in sedimentation from wind-blown deposits to colluviation of terra rossa. Direct dating of the deposits associated with the Middle Palaeolithic (MP) occupation at this area could not be obtained due to the breccia forming at the lower part of the excavation area. However, the later phases of the Middle Palaeolithic occupation at this area gave an age estimate of 45.5 ± 3.7 ka. At the entrance of the cave, there are relatively more residues associated with human use of fire. Post-depositional processes in this area include decalcification of the upper layer, cementation of the lower layer and phosphatisation due to guano decomposition, which indicates that this area was probably roofed. The ages obtained in this area range between 67.5 ± 5.5 to 56.2 ± 5.9 ka, overlapping with the occupation time of Amud cave. The evidence from Shovakh Cave presents lower intensity of occupation compared to Amud, indicating variable modes of site use by humans in the Amud drainage during the Late Middle Palaeolithic.

It accumulated within domesticated animal enclosures and it was used as fuel and fertiliser as well as construction material. While the formers were studied in details, to date, the use of dung as a construction material received less attention. Here, we present a geo-ethnoarchaeological pilot study aimed at understanding the archaeological formation processes of outdoor dung-plastered floors and the possibility to identify dung markers. We studied two house terrace in a rural village from a humid tropical environment in South India (Western Ghats). Sediment samples were collected from the plastered terrace surfaces, the terraces embankment and from forest soil controls. Multi-proxy analysis of the samples included infrared spectroscopy, phytolith and dung spherulite quantification, loss on ignition, elemental analysis and micromorphological analysis. The plastering of the floors was made by mixing a quantity of dung with water and by spreading the slurry unevenly across the terrace. This result in formation of a 0.1-to 0.5-mm-thick dung crust that the analyses showed to be rich in humified organics but with very low concentrations of phytoliths and dung spherulites. The careless spreading of the dung slurry, however, resulted in localised deposition of dung lumps that displayed relatively high concentrations of phytoliths, dung spherulites, organic matter, phosphorus and strontium. The generally low preservation of dung markers seems to be related to pre-and post-depositional processes. Forest arboreal plants are low phytoliths producer, having therefore little input of these siliceous bodies in the animal faeces. Post depositional processes included trampling, sweeping and water runoff that caused severe mechanical weathering, resulting in the heavy decay of the dung crust and the removal of dung residues from the terrace surfaces. In addition, the acidic conditions of a humid tropical environment likely promoted the complete dissolution of dung spherulites. This study provides new data and insights on the potentials and limitations of dung identification in outdoor settings in humid tropical environments. We suggest possible directions for advancing the study of archaeological dung used as construction materials.

However, by the early Iron Age, the site had shrunk to a small rural settlement. Later, in the Iron Age III / Persian-Hellenistic, only enigmatic pits and a large cemetery remained. In this paper, we analyzed plant micro-remains from the dental calculus of 15 individuals (3 from the Middle Bronze Age II and 12 from the Iron Age III / Persian-Hellenistic) and δ 13 C and δ 15 N stable isotope data from tbulk bone collagen of 74 individuals (10 from the Middle Bronze Age II and 64 from the Iron Age III / Persian-Hellenistic) and 13 Late Bronze Age animal bones (7 Ovis/Capra and 6 Bos). Our results indicate general stability of human diet throughout the Middle Bronze Age II and the Iron III / Persian-Hellenistic periods, with a reliance on C 3 plant crops and terrestrial animals also consuming C 3 plants. In the later period, the plant micro-remains indicate the consumption of C 4 plants and sedges, and the stable isotope analysis indicates differences in diet between males and females.

Cooking installations are among the most abundant features in Bronze and Iron Age archaeological sites in the southern Levant, yet until now their study has been mostly descriptive. We present a study of 11 purported archaeological cooking installations from three different Bronze and Iron Age sites in Israel in which we deployed a variety of microarchaeological techniques. We provide direct physical evidence, based on Fourier Transform Infrared (FTIR) spectroscopy demonstrating that the archaeological installations were operated with temperatures as high as 900°C. Using this technique we also demonstrate that all the mud-constructed installations studied by us were internally-fueled and therefore should be identified as Tannurs rather than the externally- fueled Tabuns. We studied in detail the quantities of ash-related microscopic remains, including opaline phytoliths, calcitic wood ash pseudomorphs and dung spherulites. We show that phytolith morphotype analysis cannot distinguish between wood-dominated and dung-dominated fuel materials, while a newly developed method that calculates the ratio of ash pseudomorphs to dung spherulites (PSR method) makes such a distinction possible.. Moreover, we experimented with the effect of partial dissolution on fuel ash PSR values and utilize the results to explain taphonomy and diagenesis associated with two types of archaeological cooking installations – pebble hearths and baking ovens. In addition, we identified micromorphological criteria that can be used to assess whether ash deposits in or above a cooking installations are in situ and/or disturbed. Taken together, all lines of evidence used in this study indicate that wood was the major fuel material across time and space in the studied archaeological contexts, while dung was a secondary source of fuel. This observation also cross-cuts different culture-historical entities (Philistines, Canaanites, Israelites and Egyptians). In addition, wood was preferred as fuel irrespective of environmental differences among the studied sites. This study is yet another demonstration of the value of integrating microarchaeological techniques and approaches to traditional macroscopic archaeology.

An interdisciplinary geoarchaeological approach, combining micromorphology, FTIR (in transmission and ATR collection modes), TGA and XRD, was used to establish a baseline on the mineralogical transformation of heated shells from aragonite to calcite and diagnostic sedimentary traces produced by roasting fire features. Our experimental design focused on three main types of roasting procedures: the construction of shallow depressions with heated rocks (pebble cuvette experiments), placing shellfish on top of hot embers and ashes (fire below experiment), and by kindling short-lived fires on top of shellfish (fire above experiments). Our results suggest that similar shellfish roasting procedures will largely create microstratigraphic signatures of anthropogenically reworked combusted material spatially Bdisconnected^ from the actual combustion locus. The construction of shallow earth ovens might entail an increased archaeological visibility, and some diagnostic signatures of in situ hearths can be obtained by fire below roasting activities. We also show that macroscopic visual modifications and mineralogical characterization of discarded shellfish might be indicative of specific cooking activities versus secondary burning.

Here, a coprolite (fossilized feces) from the 1.2-million-year-old paleontological site of Haro River Quarry in northwestern Pakistan was analyzed for paleoparasites. Micromorphological thin sectioning and Fourier-Transform Infrared Spectrometry (FTIR) analysis confirms the coprolite belonged to a bone-eating carnivore, likely the extinct giant short-faced hyena (Pachycrocuta brevirostris). Parasitological analysis shows the coprolite to be positive for Toxocara sp. To our knowledge, this is the earliest evidence for Toxocara sp. found.

However, conclusive evidence of dung tempering in archaeological ceramics is relatively rare. The aim of this study is to ascertain whether, and under which conditions, dung tempering of pottery is identifiable. To answer these questions, we assessed whether a combination of micro-particle analysis in loose sediment and thin-section petrography can reveal the addition of dung to the clay paste by focusing on faecal spherulites, ash pseudomorphs, phytoliths and coprophilous fungal spores. We analysed several series of experimentally produced ceramic briquettes tempered with different types of dung and dung ash, which were fired at a range of increasing temperatures. Our study shows that the identification of dung tempering represents a challenge, and it depends on a number of different factors, among others the original presence of dung markers in the dung used, the manufacturing process, the firing temperatures and the firing atmosphere. Overall, through a multidisciplinary approach, our work clarifies a variety of issues connected to the identification of dung in ancient pottery, highlighting the role of faecal spherulites as the most promising proxy.

Widespread ethnographic evidence exists for the addition of animal dung to clay during the proces... more Widespread ethnographic evidence exists for the addition of animal dung to clay during the process of ceramic production. The use of this material was probably very common in antiquity, given its large availability and the advantages resulting from the mixing. Organic-tempered pottery acquires enhanced plasticity, as well as a lighter weight. However, due to the high temperatures necessary to fire pottery, the dung component within the ceramic body is virtually archaeologically invisible. To this end, two series of clay briquettes were produced and tempered in equal amounts with sheep and goat fresh dung (1st series) and sheep and goat ashed dung (2nd series). Every briquette was then separately fired at different temperatures, every 100° from 300° to 800°C. Potential visibility of the dung addition is being assessed by analysing remains of phytoliths, spherulites, ash pseudomorphs and fungal spores, as well as by means of thin section petrography.

This poster presents a study of a selected group of Iron I monumental buildings in Areas A and C at the Philistine site of Tell es-Safi/Gath (Israel). These remains can be potentially situated within the context of what is known about Sea Peoples’ architecture in the Mediterranean as seen at 12th century “anaktoron” at Pantalica, Sicily. Stratigraphic excavations of the siege tower in the lower city in Area C at Tell es-Safi/Gath indicate that the tower was built on the foundations of an Iron I building. This earlier building is interpreted as a temple based on the ceramic and faunal remains associated with it. The monumentality of the building is indicated by the size of the blocks, three of which were drawn and cataloged by Hitchcock. Remains of a similarly monumental Iron I wall were uncovered and cataloged in the final season conducted in Area A at Tell es-Safi/Gath. Although the Area A structure was not completely excavated, it demonstrates that monumental architecture was more widespread in the early Philistine period than originally thought.
During the same period (12th century BC) in Sardinia appeared cult buildings such as holy wells and rectangular temples that had a wide diffusion and frequentation during the Late Bronze Age and the Early Iron age. According to some scholars, this phenomenon could be linked to a climate change that, between 1550 and 550 a. C., gave rise to a period of drought. This situation, still to be verified about Nuragic Sardinia, has been documented for the north-western area of the Mediterranean. However, the search for water as a primary good seems to be the basis of holy well and water temples where the water itself became the object of cult maybe to prevent a further decrease in water reserves.
The social changes that occurred during the Late Bronze Age led, in some cases, also to the transformation of Nuraghi into places of cult. The monumentalization of the spring vein present inside the Nuraghe Nurdole (Orani, NU) occurred during the Final Bronze Age is an example of this phenomenon. The monumentality of the architectures, realized through the use of large blocks sometimes also carefully worked, continues to be a peculiarity of the nuragic buildings that are distinguished for their specific physiognomy in the Mediterranean panorama of the Bronze Age.

Levant. However, their function is often assumed or unknown. Thirteen circular pebble
installations were found scattered throughout a residential neighbourhood dating to the Early
Bronze Age III at Tell es-Safi/Gath. Five such installations were recently studied by implementing
an integrated micro-archaeological approach by which all micro- and macro-artefacts were
analysed using various analytical techniques. Based on the analysis of ash-micro remains
identified in the sediments, associated plant remains, flint and pottery, we suggest that these
installations were used for food-processing, cooking and/or other domestic low-heat tasks. The
installations first appear at Tell es-Safi/Gath during the Early Bronze Age III, and seem to
disappear during later periods. The functional roles of these installations are discussed in
comparison to finds from other Early Bronze Age sites, and of other food preparation traditions
known from other periods and cultures.

Cooking installations are among the most abundant features in Bronze and Iron Age archaeological sites in the southern Levant, yet until now their study has been mostly descriptive. We present a study of 11 purported archaeological cooking installations from three different Bronze and Iron Age sites in Israel in which we deployed a variety of microarchaeological techniques. We provide direct physical evidence, based on Fourier Transform Infrared (FTIR) spectroscopy demonstrating that the archaeological installations were operated with temperatures as high as 900°C. Using this technique we also demonstrate that all the mud-constructed installations studied by us were internally-fueled and therefore should be identified as Tannurs rather than the externally- fueled Tabuns. We studied in detail the quantities of ash-related microscopic remains, including opaline phytoliths, calcitic wood ash pseudomorphs and dung spherulites. We show that phytolith morphotype analysis cannot distinguish between wood-dominated and dung-dominated fuel materials, while a newly developed method that calculates the ratio of ash pseudomorphs to dung spherulites (PSR method) makes such a distinction possible.. Moreover, we experimented with the effect of partial dissolution on fuel ash PSR values and utilize the results to explain taphonomy and diagenesis associated with two types of archaeological cooking installations – pebble hearths and baking ovens. In addition, we identified micromorphological criteria that can be used to assess whether ash deposits in or above a cooking installations are in situ and/or disturbed. Taken together, all lines of evidence used in this study indicate that wood was the major fuel material across time and space in the studied archaeological contexts, while dung was a secondary source of fuel. This observation also cross-cuts different culture-historical entities (Philistines, Canaanites, Israelites and Egyptians). In addition, wood was preferred as fuel irrespective of environmental differences among the studied sites. This study is yet another demonstration of the value of integrating microarchaeological techniques and approaches to traditional macroscopic archaeology.
