These features are rich sources of archaeological data.In particular, thermal features are sought as sources of datable material.Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used).This fact should always be remembered when using radiocarbon dates. Once wood is burned, it can survive in the ground for thousands of years.Uncharred wood can also survive in caves, arid areas, and water-logged areas.
Eagle Tree was a spatially extensive prehistoric campsite with a very sparse distribution of features and artifacts. Thermal features, such as hearths and burned structures, are often detectable in magnetic surveys. Presented at the 2014 Plains Anthropological Society Conference, Fayetteville AR, October 28-November 1, 2014.We have attempted to test the reliability of chronologies of 11 southern Iberian Middle and early Upper Paleolithic sites.Only two, Jarama VI and Zafarraya, were found to contain material that could be reliably dated.
