Isotopes dating archaeological finds
more The pottery investigated in this study comes from late mesolithic inland sites next to rivers in Northern Germany.
The first AMS 14C datings of food crusts from these sites showed surprisingly high ages, which could be caused by the hardwater effect.
In northern Germany, modern freshwater fish samples can have very high apparent radiocarbon ages (up to 3000 years).
Archaeological finds as well as scientific analyses of humans and their artefacts indicate the great importance of aquatic resources, both marine and freshwater, to Ertebølle subsistence.
The aim of this special themed issue of Internet Archaeology is to contribute to a better understanding of different forms of human interaction with aquatic landscapes. We consider the results of radiocarbon, stable isotope and elemental analyses of food crusts on prehistoric pottery from four sites in the Alster and Trave valleys: Kayhude, Schlamersdorf, Bebensee and Seedorf. This article discusses methods of identifying freshwater resources in prehistoric pottery, including radiocarbon reservoir effects.Modern samples from the rivers have ages of several hundred 14C years, and a modern food crust prepared from fish"American mastodon (Mammut americanum) was amongst the widest ranging of Pleistocene megafaunal species, though their fossils are rare in Alaska and northwest Canada.Questions remain about their extinction chronology at high latitudes...
