Avian resources at a Mexican site at the time of the Spanish Conquest

The time of the Spanish Conquest in America saw a major biological interchange caused by human action. In the native people it was expressed by major changes in the use of animals, due to the introduction of domestic European fauna. This theme is discussed here based on a review of ethnohistorical sources and a small body of recent archaeological evidence. An analysis is presented of the use of birds at a Mexican settlement inhabited in the sixteenth century at the time of Spanish contact. The bird remains, 456 fragments, are from the site of El Japon, southeast of Mexico City. The main avian resources were domestic fowl, Gallus gallus, turkey, Meleagris gallopavo, and four species of ducks. The exploitation of scrub jay, Apheolocoura coerulescens is recorded for the first time in Mexican archaeo-ornithology. The study confirms ethnohistorical information about the introduction of the domestic fowl, but also shows that native resources were more widely used than is known from the chronicles of the sixteenth century. © 1997 John Wiley & Sons, Ltd.     

Multi-element analysis for dietary reconstruction at a balearic Iron Age site

The number of studies using trace elements as indicators of diet has increased with time, but the majority have used few elements and a small sample. The present study has as a principal objective a multi-element analysis of diet in a large sample in which diagenetic changes have been shown to be unimportant. The analysis was made using concentrations of seven elements—Sr, Ba, Mg, Cu, Zn, V and Ca—in 197 individuals from the necropolis of ‘S' Illot des Porros’ (Majorca, Spain). The results show that these individuals would have had a mixed diet with a high meat component, principally of marine origin (molluscs and fish), but with an important consumption of seeds and cereals and a low proportion of vegetables.     

Evidence of pedogenesis from a neolithic site at Rackham,Sussex

A rich assemblage of Neolithic flints and associated charcoal lies at a depth of 15–20 cm in what is now a strongly-leached podzol. The site was probably associated with butchery and the preparation of animal materials using flint implements manufactured on the site. The pollen profile suggests that the contemporary vegetation was mixed deciduous forest and that the artifacts were buried by earthworm action. Subsequent deforestation and the development of Calluna heath would have led to the extinction of the earthworms and the development of the present podzol.     

Bison butchery at Cooper,a Folsom site on the Southern Plains

Cooper, a Folsom arroyo-trap bison kill site in northwest Oklahoma is composed of three large-scale kill episodes. The bison bones have been examined for butchering evidence and exploring the butchering pattern. Damage categories to cortical bone are indentation, cut mark, helical fracture, and impact blow. The 99 elements damaged are from 36 carcasses across all three kills, and damage morphology indicates both lithic and bone expediency tools were used in the butchering. Animals are being butchered in an upright position on their stomachs, with transverse and abdominal muscles the focal point. Experimental butchering of a bison replicates the reconstructed sequence and underscores a gourmet butchering style for the Cooper kills.

Environmental context of a Neolithic site at Beifudi,north-west Hebei Province,China

The earliest evidence of prehistoric religious practice in China found so far comes from excavations at Beifudi, about 120 km south of Beijing, in the form of votive offerings and porcelain sorcery masks dated to the period 8000–7000 yr BP. These finds are part of a rich Neolithic site located on the second river terrace on the north shore of the Yi River. This paper presents results of pollen analysis of part of a sediment profile from a depression at the edge of first terrace towards second terrace, a few hundred metres away from the main archaeological finds. A sequence of marked changes in environment occurred between 9000 cal yr BP and 6000 cal yr BP, and dating evidence suggests strong associations with the ebb and flow of human activity in the area. The first phase of activity on the site begins at around 8000 cal yr BP, towards the end of a period of relatively dry, cold environmental conditions. Between 7800 cal yr BP and 7400 cal yr BP, the first clear evidence of cereal cultivation appears in the pollen record. Rich archaeological finds occur during the same time period, suggesting local prosperity. This first phase of the Beifudi culture ends at 7300 cal yr BP, when warmer and wetter conditions are inferred and wetland areas expand, reducing the area available for crop cultivation near the site. A return to drier and cooler conditions from 6900 cal yr BP corresponds with the second phase of apparent prosperity in the archaeological record from Beifudi. This phase ends at around 6500 cal yr BP, at the start of another shift towards wetter conditions in the flood plain environment. The pollen record suggests that environmental conditions in the flood plain were a major determinant of human activity at Beifudi in the early-mid Holocene.     

Soils and the location of Cacao orchards at a Maya site in Western Belize

Cacao was one of the most important crops of the lowland Maya. Ethnohistoric sources document that the Postclassic-Colonial Period Maya settlement of Tipu in western Belize was an important cacao-growing center, yet evidence of where the cacao was grown is not apparent. We analysed the suitability of floodplain, terrace, and bedrock soils for cacao cultivation. Our results indicate that the soils most likely to have been used for cacao growth were those on the modern floodplain of the Macal River, based on their suitable physical and chemical properties. In addition, buried stone walls of Late Classic or Postclassic age that may have been used for field demarcation were found on the floodplain, suggesting that this geomorphic surface was also utilized well before the time of Spanish contact, possibly for intensive agriculture.     

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.     

Taphonomic evidence for site formation processes at fort Christanna

Fort Christanna was an early eighteenth century Indian trading post on the western frontier of Virginia. This paper describes and interprets the faunal remains recovered during three seasons of excavation at the site. Taxonomic and body part representation are examined to gain insight into diet on the frontier, food provisioning at the fort, and the relationship between the fort's occupants and the neighbouring Indian settlement. These interpretations are limited by the poor preservation apparent in the faunal assemblage. The patterning of a variety of different surface modifications is explored to understand the taphonomic history of the assemblage. These characteristics of the assemblage seem to be related largely to the bone refuse disposal practices of the fort's occupants, and thus give important insight into a crucial aspect of the site formation processes.     

Crane and vulture at an Italian Bronze Age site

Bones of a crane (probably Grus grus) and a large vulture have been found in middle Bronze Age levels of the southern Italian site of La Starza. It is suggested that these birds may have been hunted for their feathers. © 1997 John Wiley & Sons, Ltd.     

江西李渡烧酒作坊遗址盐分来源探讨

李渡烧酒作坊遗址表面聚集了大量的须状结晶物和白色致密膜状物质。在须状结晶物区域,土体表面出现了严重的疏松现象;而在白色致密膜状物质区域,土体表面未见明显的疏松现象。经检测分析,须状结晶物主要为硫酸镁的水合物,而白色致密膜状物质主要为硫酸钙的水合物。遗址表面的高盐分严重威胁着遗址的安全,因此,需要研究清楚盐分来源,以便为下一步的保护提供理论基础。研究表明,硫酸镁盐在吸失水过程中发生巨大的体积变化,是遗址岩、土体不断疏松劣化的主要原因。通过对遗址介质的可溶盐检测分析,查明盐分主要为酿酒生产过程中形成,从而为后续保护方法的研究提供了依据。     

A comparison of archaeological and dental evidence to determine diet at a predynastic Egyptian site

This paper explores the relationship between dietary evidence found in the archaeological record and that of the dentitions on a sample of working class Predynastic Egyptians from Hierakonpolis in Upper Egypt. The samples consist of 196 individuals (3800–3600BC) ranging from 6 years to over 50 years of age. Archaeological and archaeobotanical evidence at Hierakonpolis suggests manufacture of bread, presence of some domesticated animals, hunting and fishing, and a number of fruits and vegetables. Dental indicators of diet studied include carious lesions, macrowear, microwear and linear enamel hypoplasia. The patterns on the dentition match well with a number of food stuffs found as burial offerings and within settlements at Hierakonpolis. Overall, individuals at Hierakonpolis exhibited a low incidence of small carious lesions, a low frequency of acute hypoplastic defects, steady attrition, few microwear features, a low density of large (> 4 microns) pits, and wide scratches with poorly defined margins. Based on the dentition, the working class population would have relied heavily on bread and raw, but also consumed some meat and/or fish. Within sample variation shows that the proportion of certain food categories differ between adult males and females and between adults and juveniles. LEH data suggests that children suffered no long‐term starvation or chronic stress. Copyright © 2010 John Wiley & Sons, Ltd.     

Some chronological implications of a fossil molluscan assemblage from a neolithic site at Brook,Kent, England

The later post-glacial history of a valley in the chalk escarpment near Brook, Kent, is described, based on molluscan stratigraphy, archaeological evidence and radio-carbon dating. Differences in size and colour banding, respectively, of fossil and living representatives of two species of land snails, Pomatias elegans (Müller) and Cepaea nemoralis (L.), are correlated with climatic change during the post-glacial period. The problems of the use of fossil shells of these species as samples for radiocarbon dating are discussed.     

Perinatal infant death at the Roman villa site at Hambleden,Buckinghamshire, England

The aim of the current work is to investigate whether perinatal infant burials at Hambleden Roman villa (1st–4th century AD), England, more likely represent infanticides, as has been contended by earlier workers, or natural deaths. Previous work has noted that when infanticide is practiced it is normally carried out immediately after birth and so will produce an age at death distribution tightly clustered around the gestational age of a full-term infant. By contrast, natural deaths in the perinatal period produce a rather flatter age distribution. In foetal and perinatal infants, long-bone length bears a close relationship to gestational age. The distribution of age at death in the Hambleden perinatal infants is compared with those from Roman Ashkelon, Israel, where earlier work showed evidence for infanticide, and Mediaeval Wharram Percy, England, where previous studies demonstrated a perinatal age at death distribution consistent with natural deaths. The comparisons between the sites are undertaken using four different methodologies: direct comparison of distributions of long-bone lengths, and comparison of ages at death estimated using two different regression methods and using a Bayesian methodology. Results consistently show a strong clustering in the Hambleden age distribution at an age approximately corresponding to a full-term infant. In this respect they resemble results from Ashkelon and differ from those from Wharram Percy. This was interpreted as supporting the suggestion of infanticide at Hambleden.     

Medieval land remediation of a quarry site at Wallingford,Oxfordshire, revealed by microfossil analysis

Abstract

Backfill material from a 12th- to13th-century quarry, north of Wallingford, south Oxfordshire, comprises sandy loam overlain by Cretaceous (early Cenomanian; Mantelliceras mantelli Macrofaunal Biozone) Glauconitic Marl Member, of the West Melbury Marly Chalk Formation as identified by its abundant, biostratigraphically useful, foraminifera and ostracods. A local outcrop source of the Glauconitic Marl Member, less than 1 km north of the quarry pit, is the likely provenance of this material, and a contemporaneous road, which was discovered adjacent to the medieval quarry by magnetometer surveys and archaeological excavation, would have aided its transportation, into the town via the North Gate. We hypothesise that the use of a calcareous marl to overlay sandy loam deposits probably encouraged land restoration when the quarried area was returned to pastoral agriculture.

Shipwreck in a swamp: the Burroughs site at Edenton, N. Carolina, USA

This preliminary site analysis of a suspected 18th-century shipwreck located in Edenton, North Carolina, USA, helps call to question the roll of abandonment in the examination of ships as artefacts. Abandonments often provide an easily accessed and inexpensive means of fleshing out knowledge of ship construction in the past. Abandonments are typically located near historically well-used commercial ports and harbours and may now be hidden by shallow water, marshland or land fill. These areas, in many instances, are inaccessible to normal remote sensing survey techniques.
