On the use of endosteal layers and medullary bone from domestic fowl in archaeozoological studies
-
The very high incidence of medullary bone in two archaeozoological assemblages of the Roman period was believed to reflect systematic slaughtering of older hens at the end of the egg laying season. In an attempt to test this hypothesis, histological analyses were carried out. Histological data in the literature on ageing of modern fowl and on the development of medullary bone in hens are insufficient for application to archaeozoological material. Bones of modern fowl of known age were analysed with the aim of validating the use of endosteal layers for ageing. In addition, hens with known egg laying stage were studied in order to try and document differences in medullary bone development that could be related to the time of slaughtering (just before, during, or just after the egg laying season).

Fish otoliths and their relevance to archaeology: an analysis of medieval, post-medieval and recent material of plaice, cod and haddock from the North Sea
-
The growth increments were investigated of late medieval, post-medieval and modern otoliths of plaice, cod and haddock from the North Sea. Thin-sectioned otoliths were used to age all the analysed individuals and to reconstruct their growth patterns. In addition, fish lengths of the archaeological specimens were calculated after the relation between otolith width and fish length was established using modern material. The age and fish length distribution, and the growth patterns obtained on the archaeological material allow inferences about fish trade, market strategies and consumption behaviour on producer sites (coastal sites) and consumer sites. Differences in growth patterns were observed between the archaeological and recent populations of the three demersal species analysed which may be related to a change in fishing pressure through time. However, diachronic changes in species distribution, temperature, food availability and selection of catch in function of market strategies may have played a role as well. Age and body size data allow some inferences about the exploited fishing grounds, but the growth patterns are of limited use in this respect.

Osteological evidence for the draught exploitation of cattle: First applications of a new methodology
-
Although the aetiology of bone pathologies in cattle is poorly documented, various deformations in the skeleton have been attributed to draught exploitation in the archaeozoological literature. This paper summarizes the results of an osteological study that was undertaken on the feet of modern draught oxen. This led to the definition of a series of draught-related anomalies. In an attempt to describe the pathologies in a more consistent and quantitative way, a scoring scale for each individual bone pathology was established. The developed method is applied to cattle remains from four Roman and one late medieval site. The distribution of the observed pathological indices (PIs) on the first phalanges is interpreted in terms of the age structure of the cattle populations, and the possible modes of cattle exploitation and meat consumption in various settlement types.

Evidence for banana cultivation and animal husbandry during the first millennium BC in the forest of southern Cameroon
-
The faunal and botanical data from the first millennium site of Nkang, Southern Cameroon, are presented in this paper. The analysed material, retrieved from refuse pits, comprises charcoal, phytoliths, molluscs and animal bones, which allow a reconstruction of the former environment. In addition, the site provides new insights into the emergence of food-producing communities in the African rainforest. Food procurement strategies at the site involved gathering, hunting, fishing, as well as small livestock keeping and banana cultivation. This is the earliest evidence for such practices in Central Africa.

First inland records of the euryhaline goby Knipowitschia caucasica from lakes in Anatolia, Turkey
-
Knipowitschia caucasica, a euryhaline Ponto–Caspian–Aegean gobiid fish, is recorded for the first time from Lakes Egirdir, Eber and Demirköprü (Anatolia). Its presence in these lakes is probably due to involuntary introduction with common carp from hatcheries in the Edirne–Ipsala region, Thrace, the European part of Turkey.

Reconstructing age distribution, season of capture and growth rate of fish from archaeological sites based on otoliths and vertebrae
-
The growth increments of otoliths and vertebrae of plaice (Pleuronectes platessa) derived from a 15th century single depositional event at Raversijde (Belgium) are analysed with the aim of reconstructing (a) the age distribution of the population, (b) the season of capture, and (c) the growth rate. Otoliths and vertebrae give slightly different age distributions but it is possible to arrive at similar seasonality estimations in both structures when information from the literature and our own data from monthly captures of plaice from the North Sea are taken into account. These modern data show that the timing of annulus formation in otoliths and vertebrae is more or less similar. Back-calculations on vertebrae and otoliths yield similar growth curves. The age distribution, the edge condition of both vertebrae and otoliths, and the growth rate obtained on the material from Raversijde all show that the plaice from the studied assemblage were captured during spring in the southern part of the North Sea. Vertebrae are commonly preserved in archaeological sites whereas otoliths rarely survive. Although they are more difficult to read than otoliths, vertebrae of plaice can be used for growth increment analyses, and the growth rates obtained from vertebrae from archaeological sites can, therefore, be compared in the future to growth data from modern otoliths studied in sea fisheries research. Archaeozoological material predating industrialized fishing since the 19th century can hence serve as a reference in the study of the compensatory response of commercially important species to heavy exploitation.
