ESR and AMS-based 14C dating of Mousterian levels at Mujina Pećina, Dalmatia, Croatia

The paper presents the first chronometric dates for sediments that contain Mousterian industry in Dalmatia (south Croatia). Electron spin resonance (ESR) dating was conducted on two teeth from Mousterian level E1 at the site of Mujina Pećina. Additionally five bone and one charcoal sample from five different strata of origin at this site were dated by accelerator mass spectrometry (AMS). Assuming 30% moisture for both the gamma and beta dose rate calculations, the mean LU ESR age estimate is 44+/-5 ka for level E1, which is statistically indistinguishable from the mean EU ESR age estimate of 40+/-7ka. A single, uncalibrated 14C age from E1/E2 interface yielded an age estimate of 45, 170+2780/-2060 years B.P. while the mean of five samples from overlying Mousterian levels is 39+/-3. The true (calibrated) age of this mean is about 42 ka, which means that the entire stratigraphic profile in Mujina Pećina apparently was very rapidly deposited, and that ESR age, regardless of uptake model is in good agreement with calibrated 14C mean age.
