Extended Data Table 2 OSL laboratory data and ages for all samples, arranged by layer

From: Evidence from Tinshemet Cave in Israel suggests behavioural uniformity across Homo groups in the Levantine mid-Middle Palaeolithic circa 130,000–80,000 years ago

  1. Layers A-C are on the terrace; DB – dark brown layer in the first chamber; FC – first chamber, light brown layer. Grain size for all samples is 75-125 µm. Burial depth for samples from the terrace includes additional 0.6 m of topsoil that was removed during excavations. Moisture contents estimated at 10 ± 3% and 15 ± 4% for samples from terrace and chamber, respectively. Gamma dose rate was calculated from radioelement contents or averaged with dosimeters where available. For most samples, chemical analyses were carried out on several (2-5) subsamples and the values averaged. Errors on radioelement concentrations are 7-10% of the measured values. In bold are the average date for each layer. N - The number of aliquots used for calculating the De out of those measured (outliers removed). OD - overdispersion, a measure of the scatter within the sample beyond that expected from instrumental noise.
