Radiocarbon dating an archaeological perspective
Carbon entering the food web in freshwater systems is often not in full isotopic equilibrium with the atmosphere, giving rise to spuriously old radiocarbon ages in fish, other aquatic organisms, and their consumers.
These freshwater reservoir offsets (FROs) have been noted on human and dog bone in several areas of the world.
Although great megathrust earthquakes have been previously documented by coral microatoll studies, the timing of past tsunamis on Simeulue Island, west Sumatra, are poorly documented. more Although great megathrust earthquakes have been previously documented by coral microatoll studies, the timing of past tsunamis on Simeulue Island, west Sumatra, are poorly documented.
According to local residents and our recent reconnaissance, a large ...
Here we report the results of multi-tracer Bayesian dietary modeling using δ 15 N and δ 13 C values on dog bone collagen from mid-fifteenth to mid-sixteenth-century Iroquoian village sites at the headwaters of the St. Results indicate that fish was an important component of dog diets.
In Iceland, an ice-core dated tephrochronology of the archaeology of first settlement enables us to evaluate the accuracy of 14 C chronologies.
more In 1988, three laboratories performed a radiocarbon analysis of the Turin Shroud.
The results, which were centralized by the British Museum and published in Nature in 1989, provided ‘conclusive evidence’ of the medieval origin of the artefact.
We show that this approach can produce robust termini ante quos for colonization events and may be usefully applied elsewhere.
2Isotopic analysis of dog (Canis lupus familiaris) bone recovered from archaeological sites as proxies for human bone is becoming common in North America.
