“…Nonetheless, Evans and Tatham (2004) Sr/ 86 Sr. Evans et al (2010) found that the 87 Sr/ 86 Sr recorded by snail shells appears to be shifted towards that of rainwater. Furthermore, land snails also incorporate significant amounts of soil carbonates into their diet -up to 40% (Yanes et al, 2008). As a result, snail shell 87 Sr/ 86 Sr are usually biased towards values for soil carbonates, which also seems to be the case for the snail shells analyzed in this study.…”

Sr/ 86 Sr reference maps (isoscapes) are a key tool for investigating past human and animal migrations. However, there is little understanding of which biosphere samples are best proxies for local bioavailable Sr when dealing with movements of past populations. In this study, biological and geological samples (ground vegetation, tree leaves, rock leachates, water, soil extracts, as well as modern and archeological animal teeth and snail shells) were collected in the vicinity of two early medieval cemeteries ("Thuringians", 5-6th century AD) in central Germany, in order to characterize 87 Sr/ 86 Sr of the local biosphere. Animal tooth enamel is not appropriate in this specific context to provide a reliable 87 Sr/ 86 Sr baseline for investigating past human migration. Archeological faunal teeth data (pig, sheep/goat, and cattle) indicates a different feeding area compared to that of the human population and modern deer teeth 87 Sr/ 86 Sr such as freshwater bivalve shells and tree cores were examined in order to track potential historic anthropogenic contamination of the water and the vegetation. The data obtained from the archeological bivalve shells show that the modern rivers yield 87 Sr/ 86 Sr ratios which are similar to those of the past. However, the tree cores registered decreasing 87 Sr/ 86 Sr values over time towards present day likely mirroring anthropogenic activities such as forest liming, coal mining and/or soil acidification. The comparison of 87 Sr/ 86 Sr of the Thuringian skeletons excavated in the same area also shows that the vegetation samples are very likely anthropogenically influenced to some extent, affecting especially 87 Sr/ 86 Sr of the shallow rooted plants.

In short, the ␦ 13 C values of land snail records should reflect the ␦ 13 C compositions of carbon sources that the organism consumed (e.g., Goodfriend and Magaritz, 1987;Goodfriend, 1988Goodfriend, , 1990Goodfriend, , 1992Ellis, 2000, 2002;Balakrishnan et al, 2005a,b;Yanes et al, 2008Yanes et al, , 2009).

Radiocarbon Ecology of the Land Snail Helix Melanostoma in Northeastern Libya

et al. 2017

Terrestrial gastropods are problematical for radiocarbon because they tend to incorporate carbon from ancient sources as a result of their dietary behaviour. The radiocarbon ecology of the pulmonate land snail, Helix melanostoma in Cyrenaica, north eastern Libya, was investigated as part of a wider study on the potential of using terrestrial mollusc shell for radiocarbon dating of archaeological deposits. H. melanostoma was selected out of the species available in the region as it has the most predictable radiocarbon ecology and also had a ubiquitous presence within the local archaeology. The ecological observations indicate that H. melanostoma has a very homogenous radiocarbon ecology with consistent variations in F 14 C across sample sites controlled by availability of dietary vegetation. The majority of dated specimens from non-urbanized sample locations have only a small old carbon effect, weighted mean of 476 ± 48 14 C yrs, with between~1-9% of dietary F 14 C from non-organic carbonate sources. Observed instabilities in the radiocarbon ecology can all be attributed to the results of intense human activity not present before the Roman Period. Therefore, H. melanostoma and species with similar ecological behaviour are suitable for 14 C dating of archaeological and geological deposits with the use of a suitable offset.
