ABSTRACTSAge determinations of kill sites, where charcoal is generally absent, has usually depended on radiocarbon analyses of bone material. However, it has been seen with known‐age samples that these dates are often in error due to contamination by plant products or ground water carbonates. The use of soil samples from strata both above and below, as well as the level containing the artifacts, offers important advantages. The soil profiles present sequences of dates, whereas the bones are only individual samples. The distribution of the soil date values can indicate upper and lower limits for the age of the kill site.The Taima‐taima paleo‐indian site in the state of Falcón, Venezuela is presented as an illustration of the application of radiocarbon dating of soil to archaeological problems. A total of 22 samples were processed. It is seen that soils from two profiles indicate a dating of 13 000 years for the kill. Taking into account reasonable extents of error, uncertainties of ± 2000 years can be estimated. The non‐carbonate fraction dates are in agreement with the earth samples, but this is probably due to the organic matter extracted from these materials being mostly soil contamination in the porous bone matrix.Fluorine measurements on the bones confirm the Pleistoce
