The application of numerical techniques to insect assemblages from the site of Stóraborg,Iceland

The problems of interpretation of many overlapping species lists of fossil assemblages are discussed using the example of insect faunas from a late medieval farm site in southern Iceland. Numerical techniques were employed, principally those available within the CLUSTAN package, and it was concluded that a considerable refinement in interpretation was achieved. Such quantitative procedures are suitable for groups other than fossil insects but their employment cannot be regarded as a substitute for, rather than an adjunct to, a sound ecological approach.     

The utility of livestock dung for reconstructing recent ethnological and environmental histories

Animal dung is evaluated here as a tool to reconstruct recent societal and environmental changes. Studies completed on the macro- and micro-contents from dung deposited in a mountain cave in Catalonia during the 1970–1980s, preceding the socio-economic changes in the area, was supplemented by the testimony of the last shepherd alive in the area. This information was also compared with evidence from aerial photographs of the area surrounding the cave taken in 1956 and 2009. Although taphonomic distortion of the dung shape precluded its assignment to its producers based on morphology, information from the organic remains reflects the agro-pastoral activities in the mountainous area of the Catalan coast. A lack of calcium phosphate and abundant phytolith and epidermal remains from wild species indicates that the dung was excreted by ovicaprines, who sheltered in the cave during spells of adverse weather. These indicators also signify that the animals fed only on natural vegetation. Insect remains in the dung include fragments of chafers, dung and ground beetles, bees and ants, and whilst the latter may have foraged in the cave, the others may have been accidentally ingested by herbivores. The nannofossils and diatoms found in the dung derive from tertiary crops 4 km away from the cave but within the range of the ovicaprine herd. The lack of cereal and vegetable remains in the dung is consistent with the ethnographic record that shepherds and farmers could not afford to supplement the herds’ diet with fodder crops or grain, a consequence of the low productivity of the local subsistence agriculture. This study further discusses the socio-economic impacts of the introduction of intensive farming, industrialisation and tourism in Catalonia during the latter part of the last century and how they are represented in the dung.     

When a ‘Waterhole’ Is Full of Dung: An Illustration of the Importance of Environmental Evidence for Refining Archaeological Interpretation of Excavated Features

Prehistoric field systems sometimes encompass excavated, pit‐like features which are difficult to classify due to the complex stratigraphies resulting from reuse, infilling and collapse. They are frequently classified as wells and watering holes, but other potential uses for excavated depressions are rarely cited. We argue the need for environmental archaeology in the interpretation of features of this nature, and present a case study from a Bronze Age site at Pode Hole, near Peterborough (UK), where fossil insect material clearly contradicts the archaeological interpretation. We present empirical evidence for a sealed context filled with dung which cannot be interpreted as a water source. This evidence strongly contrasts with other superficially similar features at the site.     

Caught in a trap: landscape and climate implications of the insect fauna from a Roman well in Sherwood Forest

Sherwood Forest in Nottinghamshire is often considered a well-preserved ancient landscape, subsequently having survived by way of centuries of management as a hunting preserve. Archaeological evidence suggests otherwise, with an enclosed landscape beginning in the pre-Roman Iron Age and continuing through the Roman period. Due to the nature of the region’s soils, however, there is little empirical, palaeoecological evidence on its environmental history prior to the medieval period. This paper presents an insect fauna from a Roman well in a small enclosure in north Nottinghamshire, on the edge of Sherwood Forest, and its interpretation in terms of contemporary land use. Wells and small pools act as large pitfall traps and may effectively sample aspects of the local and regional insect fauna. The Wild Goose Cottage fauna and its environmental implications are also compared with a number of archaeologically and geographically similar contexts.     

Integrating human dimensions of Arctic palaeoenvironmental science: SEAD – the strategic environmental archaeology database

Environmental change has a human dimension, and has had so for at least the last 10 000 years. The prehistoric impact of people on the Arctic landscape has occasionally left visible traces, such as house and field structures. More often than not, however, the only evidence available is at the microscopic or geochemical level, such as fossil insect and seed assemblages or changes in the physical and chemical properties of soils and sediments. These records are the subject of SEAD, a multidisciplinary database and software project currently underway at Umeå University, Sweden, which aims to create an online database and set of tools for investigating these traces, as part of an international research infrastructure for palaeoecology and environmental archaeology.     

Underneath Ranefer's floors – urban environments on the desert edge

The city of Akhetaten, modern day Amarna, was founded by the monotheist pharoah Akhenaten as his new capital ca. 1353 BC, and abandoned within about 25 years. Much of the site has been excavated over the past century and few deposits remain undisturbed. In one house, however, that of the king's chief charioteer, Ranefer, rebuilding had sealed occupation debris beneath the final mud brick house floors and in the desiccating conditions of the desert, these preserved extensive insect faunas, which for the first time provide detailed data on living conditions and pest infestation in a major pharaonic urban centre. Pests of stored products include the grain weevil, Sitophilus granarius, the lesser grain borer, Rhizopertha dominica, and flour beetles, Tribolium castaneum, as well as more general pests, such as the lesser mealworm, Alphitobius diaperinus, and the biscuit beetle, Stegobium paniceum. Flies include the house fly, Musca domestica, and the puparia of a flesh fly, Sarcophagidae, burrowed vertically into the mud-brick floor in a room corner, perhaps beneath abandoned offal or meat. The taphonomy of the insect assemblages would suggest that much consisted of material dumped into the house plot, either during a phase of abandonment or to level up the area before the later house, that of Ranefer, was constructed. Trampled surfaces within the midden, often consolidated with desert sand, indicate foul damp conditions and also imply that the process was intermittent. Living conditions in the city of Akhenaten are likely not to have been as salubrious as contemporary tomb paintings might suggest.     

Archaeology and environment in York

Despite extensive excavation work both in the City and Vale of York, there has been little attempt to synthesize the considered wealth of biological information which has occurred. This paper discusses some of the preliminary results obtained by the Environmental Research Team of the York Archaeological Trust and endeavours to relate these into the rather inadequate regional background, a mosaic, which, even in comparatively well-studied fields such as animal and human bones, still has more holes than pieces. Considerable emphasis is placed upon the more recently developed lines of research, particularly the insect remains, since it is felt that these have much more to offer than is realized by most archaeologists. The final section reviews certain aspects of the interaction between man and his environment, particularly the climate, in relation to the limited amount of evidence as yet recovered from York. This research has stressed the additional amount of information which can be gained by a close association of field archaeologist, historian and environmental scientists.     

The interpretation of a group of Saxon pits in Southampton

Environmental material from waterlogged pits on a Saxon site in Southampton is examined and interpretation attempted. It is suggested that the material largely represents waste from a butcher's yard, although the lack of associated structural evidence makes interpretation difficult.
