The Never-Ending Story? The Lessons of Fifteen Years of Archaeological Monitoring at the Former Island of Schokland

Abstract

The former island of Schokland became part of the mainland of the Netherlands when the Noord-Oost polder was drained in the 1940s. Mesolithic camp sites, Neolithic and Bronze age settlements, and medieval dwelling mounds (terps) on Schokland and in its immediate surroundings now form a UNESCO World Heritage site.

The main threat to the former island and the archaeology is drying out of the soil profiles, causing degradation of organic remains. Because of this, on the island and in its immediate surroundings the groundwater table is kept high in a specially created hydrological zone.

Schokland was one of the first sites in the Netherlands to be monitored in order to assess threats to the archaeological record and ongoing degradation processes. Monitoring started in 1999, and subsequent measurements were taken in 2001, 2006, and 2009/10. This included measurements of groundwater tables, water composition, redox, soil moisture and soil chemistry, micromorphology, and the degradation of botanical remains and bone. This time series of measurements makes it possible — first and foremost — to study long-term effects and changes in the Schokland burial environment, and their effects on the archaeology. In addition, the development of monitoring techniques around Schokland illustrates how the field of archaeological monitoring has evolved over the years.

Since the first monitoring round in 1999, developments in monitoring have included (1) technological developments enabling monitoring of high-frequency variations in groundwater, redox, and moisture contents, for example; (2) growing knowledge of degradation processes and the relevant characteristics of the burial environment; and (3) an increase in easily accessible datasets from third parties. Worries have arisen about the long-term storage and availability of monitoring data.

For future monitoring rounds, the value of the various monitoring techniques need to be critically evaluated, and the purpose of monitoring specific sites need to be reconsidered.     

Fowling during the Gravettian: the avifauna of Pavlov I, the Czech Republic

This is the first article that describes in detail the bird remains from the Gravettian mega-site Pavlov I in the Czech Republic. More than 1000 bird bones represent at least 19 taxa, of which the most numerous are tetraonids including black grouse (Tetrao tetrix), willow grouse (Lagopus lagopus) and ptarmigan (Lagopus muta), and ravens (Corvus corax). The archaeological and biological contexts indicate that most birds were hunted by people in the vicinity of the site, possibly with the help of knotted nets made from plant fibres. We suggest that ravens were killed while feeding on carcasses and/or food remains that may have been disposed of intentionally, and feathers may have been used for arrow fletching. Human-modified bones indicate that birds were used not only for food but also as raw material for tools and decoration. Although mammals were certainly more important in the subsistence of the Gravettian people, it is clear that birds played a role in their culture. The location of Pavlov I enlarges the explanatory scope of the Broad Spectrum Revolution hypothesis to include higher latitudes north of the Mediterranean.

Soil fertility and slope processes in the Western Cumberland Escarpment of Kentucky: influences on the development of horticulture in the Eastern Woodlands

The archaeological record of dry rockshelters in the Red River Valley of eastern Kentucky contains botanical remains of several weedy annual seed-bearing plants that point to the independent development of agriculture during the Late Archaic and Early Woodland Period. The objective of this study is to gather quantitative data through the chemical and physical analysis of soils collected within a valley transect to gain insights into landscape processes and soil fertility that may have played a role in the early development of plant domestication and the location of garden plots in relation to rock shelter sites in the upper Cumberland Plateau region of eastern Kentucky. Soils on upland benches formed in limestones have soil fertility values that are comparable to fertile floodplain soils. Upslope outcrops of calcareous bedrock are contributing basic cations to these bench soils. Additionally, in comparison to other landscape positions these upland soils have high levels of organic carbon, available P and greater C:N ratios. Soil morphology, radiocarbon dates, and archaeological evidence indicate that many of the numerous earthflows and debris flows within the region are Early to Middle Holocene in age. These slides were likely generated by Mid-Holocene climatic shifts in which the frequency and intensity of summer precipitation increased across the southeastern United States. These slope failures may have contributed to the development of plant domestication by creating forest canopy gaps and disturbed soils in which weedy plants thrived.     

Using plant microfossils from dental calculus to recover human diet: a case study from Tell al-Raqā'i,Syria

Dietary reconstructions based on plant microfossils, such as starch grains and phytoliths, have been useful in increasing our understanding of past human populations. Microfossils have been recovered from sediments, stone tools, and, more recently, dental calculus. Methods for recovering microfossils from dental calculus have yet to be firmly established and there is some question about potential damage to the teeth. Using a sample of teeth from the middle Holocene site of Tell al-Raqā'i, Syria, we tested using a dental pick to sample the calculus. ESEM images taken before and after sampling show no damage to the enamel surface, and examination of the recovered microfossils show that this method provides ample material for study, even when not all of the calculus is removed from the tooth. Preliminary identification of the plant microfossils suggests that these individuals were consuming a variety of plant foods, but that domesticated cereals such as wheat and barley made up a surprisingly small portion of their diet.     

Taphonomic analysis of leporid remains obtained from modern Iberian lynx (Lynx pardinus) scats

Distinguishing leporid bones accumulated by diurnal raptors, owls, mammals and humans is essential to understand not only past human subsistence activities but also past ecology. This is particularly relevant in Iberian Palaeolithic sites where leporid remains usually constitute the most abundant taxon. As far as terrestrial mammal carnivores are concerned, the Iberian lynx (Lynx pardinus) would be the main leporid predator in the Iberian Peninsula. Up until now its contribution as a rabbit bone accumulator in archaeological sites has never been properly assessed. In order to investigate the taphonomic signature of this predator the analysis of 33 samples of modern Iberian lynx scats was carried out. Results show that leporid remains consumed by this carnivore appear very fragmented and exhibit a strong degree of corrosion digestion. Cranial elements are most abundant followed by long bones. Whereas there seem to be clear differences in relation to breakage and digestion alteration caused by owls, some of the patterns obtained are closest to those established with diurnal raptors.     

New Directions in Bioarchaeology: Recent Contributions to the Study of Human Social Identities

As a discipline that bridges the biological and social sciences, bioarchaeology has much to contribute to a contextualized and theoretically sophisticated understanding of social identities. Here, we discuss the growing methodological sophistication of bioarchaeology and highlight new developments in osteological age and sex estimation, paleodemography, biodistance analysis, biogeochemistry, and taphonomy, particularly anthropologie de terrain. We then discuss how these methodological developments, when united with social theory, can elucidate social identities. More specifically, we highlight past and future bioarchaeological work on disability and impairment, gender identity, identities of age and the life course, social identity and body modification, embodiment, and ethnic and community identities.

Compensatory bone remodelling in moose: a study of age,sex, and cross‐sectional cortical bone dimensions in moose at Isle Royale National Park

We studied interrelationships among age, sex, and cross‐sectional cortical bone dimensions using quantitative computed tomography (QCT) scans of metatarsal bones of 180 moose (Alces alces) that died in Isle Royale National Park, Michigan. As a large‐bodied quadruped with demanding ecological constraints on movement and behaviour, a moose experiences different weight‐bearing and mechanical stressors than humans, to whom most existing studies of mechanical adaptations of bone pertain. In moose, both sexes showed significant subperiosteal expansion and an increase in medullary area, with an overall increase in cortical bone area over time. Female moose did not exhibit cortical thinning or reduction in cross‐sectional area with age, rather they showed an increase in cortical bone area with periosteal apposition exceeding endosteal resorption, similar to the males. We also found that moose undergo changes in bone geometry through remodelling of bone similar to humans, suggesting a compensatory mechanism for increasing bone strength under conditions of decline in bone mineral density with age.
