The following problems regarding the ESR dating of fossil enamel samples from palaeo-anthropological and palaeolithic sites of Early Pleistocene are discussed:1) the applicability of exponential fitting in the additive method for reliable AD determination
2) the thermo-stability of the g= 2.0018 line of hydroxyapatite and its influence on apparent ESR ages; 3) the right selection of U-uptake models
and 4) the effect of high U-content in enamel on the ESR ages. It is concluded that the ESR-EU ages of Early Pleistocene enamel samples can only be regarded as the lower limit of the true ages if no appropriate corrections for the factors discussed above are made.
