Stable Isotope Evidence for Late Medieval (14th–15th C) Origins of the Eastern Baltic Cod (Gadus morhua) Fishery

Although recent historical ecology studies have extended quantitative knowledge of eastern Baltic cod (Gadus morhua) exploitation back as far as the 16th century, the historical origin of the modern fishery remains obscure. Widespread archaeological evidence for cod consumption around the eastern Baltic littoral emerges around the 13th century, three centuries before systematic documentation, but it is not clear whether this represents (1) development of a substantial eastern Baltic cod fishery, or (2) large-scale importation of preserved cod from elsewhere. To distinguish between these hypotheses we use stable carbon and nitrogen isotope analysis to determine likely catch regions of 74 cod vertebrae and cleithra from 19 Baltic archaeological sites dated from the 8th to the 16th centuries. δ13C and δ15N signatures for six possible catch regions were established using a larger sample of archaeological cod cranial bones (n = 249). The data strongly support the second hypothesis, revealing widespread importation of cod during the 13th to 14th centuries, most of it probably from Arctic Norway. By the 15th century, however, eastern Baltic cod dominate within our sample, indicating the development of a substantial late medieval fishery. Potential human impact on cod stocks in the eastern Baltic must thus be taken into account for at least the last 600 years.

The globalization of naval provisioning: Ancient DNA and stable isotope analyses of stored cod from the wreck of the Mary Rose, AD 1545

A comparison of ancient DNA (single-nucleotide polymorphisms) and carbon and nitrogen stable isotope evidence suggests that stored cod provisions recovered from the wreck of the Tudor warship Mary Rose, which sank in the Solent, southern England, in 1545, had been caught in northern and transatlantic waters such as the northern North Sea and the fishing grounds of Iceland and Newfoundland. This discovery, underpinned by control data from archaeological samples of cod bones from potential source regions, illuminates the role of naval provisioning in the early development of extensive sea fisheries, with their long-term economic and ecological impacts.

The domestic fowl and other birds from the Roman site of Mons Claudianus, Egypt

At the Roman quarry settlement of Mons Claudianus in the Eastern Desert of Egypt extreme aridity has preserved large amounts of organic matter. Amongst the faunal remains were several hundred bird bones, together with feathers and egg shell. The majority of the bird bones have been identified as domestic fowl Gallus gallus. Other species are rare: they include a few passage migrants and resident species. Finds of spurred tarsometatarsi and bones with medullary deposits indicate that both male and female domestic fowl are represented. It is likely that they were transported to the site from the Nile valley alive; some may have been kept at the settlement. Cut marks suggest that some at least were eaten, but the birds may have been used for different purposes, both secular and ritual.

Making the most of it : Late prehistoric pastoralism in the Avon Levels, Severn Estuary

A combination of archaeological and palaeo-environmental field work in the Avon Levels, western England, has enabled a much better understanding to be reached of the complex Holocene sedimentation in this part of the Severn Estuary, and of the close relationship between the upper part of that sequence and opportunities for exploitation of this wetland region during the later prehistoric and Romano-British periods. This paper explores that relationship, focusing in particular on two Iron Age to Romano-British sites. Both sites, at Hallen and Northwick, appear to have been short-lived and only seasonally occupied in order to exploit rich grazing but this occupation took place at different times and within rather different patterns of land-use. The paper concludes with an outline model for the human use of the Avon Levels from the Neolithic to Romano-British periods.

Big fish and great auks: Exploitation of birds and fish on the Isle of Portland, Dorset, during the Romano-British period

Abstract The paper considers the assemblage of bird and fish bones from a Romano-British settlement on the Isle of Portland, on the southern coast of England. Compared with contemporary sites, the assemblage includes an unusually large number of fish bones from a wide range of marine species, including large cod, other Gadidae, several species of seabream, scad and bass. The bird assemblage includes bones of a butchered great auk. This provides the first evidence that this extinct species was nesting off the shores of central southern England and being exploited for food in this period. Other seabirds identified included razorbill, great northern diver and gannet. The species represented are discussed in relation to other Romano-British sites, particularly the Roman town of Dorchester, situated 15 km away. Many of the species have been discovered on only a few contemporary sites and the presence of the seabream in particular indicates that seawater temperatures may have been warmer than until very recently. Possible cultural changes in diet and food procurement in the Roman period are also considered.
