Traditionally, archaeologists have preferentially selected point-provenienced, large pieces of charcoal for radiocarbon dating. Examining post-depositional processes affecting charcoal suggests that these items are usually remnants of inner portions of much larger pieces of fuel wood that were burned in a feature. Radiocarbon dates on heartwood and later wood are potentially hundreds of years different, resulting in an age determination that has little to do with the use of the feature. ...
