Phosphatic mineralization of seeds from archaeological sites

Recent investigations of botanical material from archaeological sites have provided seeds and plant remains exhibiting a crystalline or semi-crystalline appearance. X-ray diffraction and partial chemical analysis have revealed that the particular plant materials had been replaced by calcium phosphate. Using systematic sampling and retrieval techniques a significant body of data has been accumulated. Most mineralized botanical evidence has been recovered from faecal deposits, in particular cess pits and garderobes, and has provided an important source of information about aspects of diet of past populations.     

Report on Finds from the Saint-Quay-Portrieux Wreck, France

In 1987, some divers discovered the cargo of a merchant ship which was wrecked off the rocks of the Saint-Quay Islands in Brittany. Several expeditions were conducted by the discoverer, DRASSM and the Art and History Museum of Saint-Brieuc on the site between 1987 and 2003 but the wreck remains unidentified. The ship is believed to have traded with Africa in the first part of the 18th century. Though no remains of the ship's structure were found, the artefacts recovered, including trading goods, ship's equipment, and domestic utensils, allow comparisons to be made with other contemporary materials.

微纳米气泡清洗“南海一号”出水瓷器的安全性评价研究

随着我国水下考古事业的蓬勃发展,出水文物的科学保护已成为亟待解决的重要问题。表面各种附着物的清除是出水瓷器清洗的难点,现有的机械和化学清洗方法均存在着一定的局限性。在试清洗实验中,微纳米气泡展现了存在时间长、传质效率高、表面电荷形成的ζ电位高等不同于普通气泡的物理化学特性,对出水瓷器具有优越的清洗效果,因此有必要进一步对该清洗技术开展科学的安全性评价。选取打捞自"南海一号"的18件瓷片样品,进行了现状调查与病害检测,使用色差分析、光泽度分析、显微分析、显微测量等方法开展了安全性评价研究。实验结果表明,未发现微纳米气泡清洗技术会导致出水瓷器自身的颜色与光泽度产生明显变化,未发现其会导致瓷器釉面损伤,也未发现其会对瓷器已有裂缝产生影响。现有的评价结果表明,微纳米气泡清洗技术对于出水瓷器是基本安全的,为该技术在文物保护工作中的实际应用提供了重要依据。     

Post-Roman crop production and processing: Archaeological evidence from Goldthorpe,South Yorkshire

The remains of a ditched field system dating from the late Iron Age to the early post-Roman period, and two associated corn drying ovens (dating to the 5th–6th centuries AD) were revealed during archaeological excavations at Goldthorpe, South Yorkshire. The site was excavated during 2012 and 2013, during which bulk environmental samples were taken in order to retrieve any surviving botanical remains from deposits associated with the corn drying ovens, and other features across the excavated area. Early post-Roman occupation is under-represented in the archaeological record, especially in northern England, as such human activity and subsistence during this period are currently not well understood. This paper combines evidence for the field system, the physical remains of the corn drying ovens and their associated botanical remains to further understand early post-Roman change and continuity in landscape use and crop production and processing practices.     

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.     

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.     

Exotic plants from Roman waterlogged sites in London

An extensive range of plant remains was recovered from seven Roman sites in London where waterlogged conditions had resulted in good preservation. In the majority of cases the “artificial” nature of urban deposits precludes any objective ecological interpretation, since the allochthonous origin of the plant remains cannot be satisfactorily established. However, the presence of exotic plants in dated deposits is of both botanical and archaeological significance and is here artificially treated as an autonomous group. This varied group of plants (excluding carbonized cereals) is arranged according to their use and put in archaeological and botanical perspective. Species such as cucumber (Cucumis sativa), gold of pleasure (Camelina sativa), peach (Prunus persica), olive (Olea europaea) and millet (Panicum miliaceum) have not been recorded from Romano-British sites before. For many of these plants their status, either as introductions or imports, is uncertain. Whichever is the case, it is clear that a wide variety of economic plants was available in Roman London.     

The Denbigh Project: excavation of a Civil War blockade-runner, J. Barto Arnold III

The blockade-runner Denbigh , one of the most successful and famous of the American Civil War, was located and recorded near Galveston in December, 1997. The site, 41GV143, was identified during a reconnaissance by the Institute of Nautical Archaeology, Texas A&M University. The 182-ft (55.5 m)-long, iron hulled, 258-ton displacement side-wheeler was built in 1860 by Laird, Sons & Co. of Birkenhead as a coastal paddle steamer and, when new, was considered a crack ship with all the latest features of design and technology.
This paper covers the 2000 excavation phase of an underwater archaeology project to investigate the Denbigh . It is the third in a series of preliminary progress reports. The report also provides updated findings on the ship's history.     

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.     

Faecal biomarker and archaeobotanical analyses of sediments from a public latrine shed new light on ruralisation in Sagalassos, Turkey

A public latrine in the ‘Imperial Baths’ of Sagalassos was transformed into a dump site in the early Byzantine period. Several layers of urban waste, including ceramics, bones, glass and perhaps excrements were deposited on the floor. Faecal biomarker analyses and archaeobotanical analyses were conducted to reconstruct the history of the room. 5β-stanols of human origin, such as coprostanol, were found in the sewage channels together with mineralised plant remains, indicating a human faecal context. The botanical remains are furthermore representative of the Roman diet of the Sagalassians. Soil layers, deposited on top of the latrine floor and dating to the early Byzantine period, contained herbivore derived 5β-stanols, such as 5β-stigmastanol and epi-5β-stigmastanol. Additionally, a clear predominance of epi-5β-stanols over 5β-stanols showed that the animal dung has been subject to composting. In this period, the former latrine was clearly used as a manure production site which is further confirmed by stratigraphic evidence of large amounts of urban waste artefacts, which were commonly collected together with manure before application on the fields. The results of the present study support the theory that off-site potsherd scattering can be used as a proxy for manuring events. Additionally, the data show key evidence for vertical migration of 5β-stanols and presumably also for the leaching of bile acids.     

The Food Remains from Casselden Place, Melbourne, Australia

Each of the major food sources are discussed in detail with reference to historical records regarding the price of various supplies and their availability at the time.     

Economic and Land-Use Implications of Prehistoric Fire-Cracked-Rock Piles,Northern Arizona

Abstract

Intensive archaeological survey of 14.5 sq km of the Upper Basin, an area located near the Grand Canyon's eastern South Rim in northern Arizona, has discovered 126 fire-cracked-rock piles that are surrounded by artifact scatters of varying size and assemblage composition. Because these phenomena are unprecedented in upland conifer ecosystems of the American Southwest, several hypotheses are explored regarding their formation histories. Analyses of artifact assemblages, botanical remains, pollen, and faunal remains recovered from four excavated sites indicate that they result from flaked-stone artifact production, ground-stone artifact reuse and recycling, ceramic-vessel-fragment recycling, and animal and plant processing. In addition, radiocarbon dates and temporally diagnostic projectile-points and ceramics imply that the sites differ in terms of frequency, intensity, and patterns of use, and with respect to the groups of people who formed them (Anasazi, Cohonina, Havasupai, or Hopi). Byproducts of a little-known, long-term land-use pattern in Southwestern prehistory (ca. A.D. 417–1650), these sites represent a key source of information for understanding how different sources of variability come to be expressed in archaeological landscapes.     

Discovery of Ancient Harbour Structures in Calabria, Italy, and Implications for the Interpretation of Nearby Sites

During underwater survey around Crotone, Calabria, Italy, in 2005, structures from two harbour phases were located, possibly dating from the Archaic Greek and Roman periods. Both harbours are close to the Greek and Roman architectural remains on Capo Colonna, as well as to underwater deposits of large stone blocks and other, previously-excavated sites. With the discovery of these harbour structures, new hypotheses arise for understanding the building-material deposits and excavated sites. A critical component of these hypotheses is the assessment of local geological data, specifically ancient sea-level, in relation to the archaeological record.

Dung matters: An experimental study into the effectiveness of using dung from hay-fed livestock to reconstruct local vegetation

This paper explores the relationship between standing vegetation and dung from hay-fed cattle and sheep. In an experimental study, hay is retrieved from a known hay field, surrounded by a semi-open landscape of hedgerows, forests and heather fields. The hay is fed to cattle and sheep, after which the dung is collected and from which the botanical remains are analysed, according to archaeobotanical standards. The results from the macro-remains are compared to vegetation relevés from the hay field. The pollen analysis is compared to both the hay field and the surrounding vegetation. Results from the plant macro remains provide an excellent representation of the vegetation in the field itself on the presence/absence level. Pollen analysis reflects the regional vegetation very well and are comparable with ‘surface samples’.     

MICROSCOPIC IDENTIFICATION AND SOURCING OF ANCIENT EGYPTIAN PLANT FIBRES USING LONGITUDINAL THIN SECTIONING*

Plant fibres and the artefacts constructed from them often remain overlooked in the archaeological record because of their poor survival and the problems related to the precise identification of the species to which the fibres belong. The goal of this study was to design a simple and accurate method of identifying archaeological plant fibre sources. Twenty‐two fibre samples from two sets of ancient Egyptian botanical artefacts were examined under both a stereomicroscope and a compound microscope, and compared to a large reference collection and to previously published research. By examining longitudinal thin sections of the ancient plant specimens, we identified plant fibres from the following species: Hyphaene thebeica, Cyperus papyrus, Desmostachya bipinnata, Imperata cylindrica, Phragmites australis and Linum usitatissimum. Our identification of these plant fibres reveals essential information about the materials used for producing ropes, baskets, sandals, mats and fabric. The results of this study demonstrate the value of longitudinal thin sectioning and light microscopy as a major means of identifying the source material of botanical artefacts, and advance our knowledge of ancient Egyptian plant exploitation as well as the associated technologies involved in constructing these types of artefacts.     

The potential of paleoethnobotanical evidence for the study of Teotihuacan foodways

Macro- and microscopic plant remains recovered from excavations at Teotihuacan over several decades contribute to an understanding of the subsistence resources available to the city’s inhabitants. However, associated contextual evidence may be inconclusive regarding the specific uses of the plants in question and, particularly, whether their presence or relative abundance indicates processing and consumption or the consequence of depositional processes. While the analysis of archeological plant remains is necessarily an interdisciplinary endeavor, involving aspects of botany, ecology, ethnography and history among other disciplines, contextual archeological evidence provides the matrix for interpretation. In this paper, we explore direct archeological evidence for plant use, considering the significance of appropriate contextual evidence (e.g., activity areas, associated ceramics, lithics, etc.) and the potential complementary role of analytical techniques such as residue analyses, and carbon isotope signatures in faunal and human osteological remains as well as stratigraphic sediments.     

Small things in perspective: the contribution of our blind tests to micro-residue studies on archaeological stone tools

Our blind tests are distinctive for they were conducted on replicated stone tools used for a variety of tasks that included the processing of animal remains and plants. The analyst was required to differentiate an array of residues from microscopic morphological characteristics, using light microscopy. The original aim of our first tests was to assess the analyst's ability to identify a variety of plant and animal residues, but issues and problems that arose during the testing process made it clear that greater value might be gained from the lessons that we learnt about methodology and the direction for future micro-residue research. We show that problems identified during our first tests stimulated research. Amongst other things, we learnt to distinguish plant and animal remains more confidently than previously. Our residue analyses are firmly embedded in wider archaeological research and our tests help to explain why there are sometimes contradictions between the evidence from archaeologically recovered remains and residues on stone tools. A further outcome of the tests is that we have adopted a multi-stranded approach that provides a cautious, but secure strategy for identifying and interpreting use-residues. Our studies of contaminants through replications have also been invaluable for distinguishing incidental residues from use-related residues.     

Taphonomy and sample size estimation in paleoethnobotany

This paper investigates how to gain quantitative comparability of macroscopic plant remains by estimating sample sizes representative to each population. First, this study reviews taphonomic pathways of plant remains to clarify how far we can draw cultural implications from the retrieved remains. The target population is defined here as the deposited assemblage, that is, plants that were deposited into the soil matrix. Through time, the deposited assemblage becomes reduced to the fossil assemblage, which is subject to being sampled (sampled population). The relation between the sampled population and samples is a statistical issue. A systematic recovery and a well-designed sampling strategy can help maintaining the same degree of representativeness of samples to the sampled population. The paper thus focuses on a statistical measure that estimates the sample sizes, based on a relative error and a confidence level of a small number of pilot samples. Data for the test is the plant remains recovered from the Nam River sites in south-central Korea, dating to the Early and Middle Mumun periods (3400-2400 BP). This measure ensures that quantitative differences between the plant remains in the two samples were due to real differences between the populations from which they were drawn rather than due only to variation within a single population. Thus this method strengthens cultural interpretations on quantitative differences in plant remains.     

Report on Underwater Excavation at the Phoenician Harbour,Atlit, Israel

Atlit is a small Phoenician settlement on the Carmel coast, with an artificial harbour, built during Iron Age II, before the Assyrian occupation, and used until the end of the Persian era. There are no remains of any later construction, in contrast to other Phoenician ports such as Sidon and Tyre. The study of Atlit harbour has therefore provided invaluable information on the positioning, planning and construction of Phoenician harbours in the Levant. This article is a summary of the most recent underwater excavation seasons at the harbour, and presents our conclusions on construction techniques and their historical implications. © 2009 The Author     

Original DocumentsExtracts from the Pipe Roll of the Exchequer, 21 Edw. III. (A.D. 1353), Relating to the Early use of Guns and Gunpowder in the English Army

This report is concerned with a sampling excavation of Bronze Age, Roman and late Saxon/early medieval settlement traces near the church at Wraysbury, Berkshire. The most extensive evidence is for an agricultural settlement of the late ninth to twelfth centuries A. D. based on a series of ditched enclosures and trackways. The settlement moved location during the eleventh century. The environmental evidence is particularly important. A large faunal assemblage including extensive fish remains exists for the late Saxon and medieval phases as well as an unusual collection of charred plant remains. There are important groups of Late Bronze Age and Saxon pottery.
