dc.description.abstractTwo Stegomastodon waringi teeth from Brazilian northeastern megafauna were dated by electron spin resonance (ESR) spectroscopy. The samples were collected in Pernambuco state, Brazil. The dating of these samples will contribute to the better knowledge of megafauna presence in this region as well as to the events associated to the extinction of these species. Additive dose method was used to evaluate the archeological dose (AD) and a non-linear relation between ESR signal amplitude and dose was obtained. The AD obtained by the exponential fitting was 120 ± 1 and 112 ± 1 Gy, leading to an estimation of an age of 63 ± 8 and 60 ± 9 ky for radioisotope early uptake model, 64 ± 8 and 60 ± 9 ky for linear uptake and 60 ± 9 ky for a combination of uptake processes.
