“…In fact, enamel histology facilitates the timing of the highest 87 Sr/ 86 Sr ratios of the tooth profile (> ~ 0.7097) to represent ~ 15 and ~ 100 days after birth and again between ~ 280 and ~ 325 days with lower values representing the ~ 3 intervening months. Such elevated ratios match several areas of the Northern Italian Alps 52 , whose bedrock geology for example include Variscan metamorphic rocks or various clastic rock formations, and overall suggest that the child was not born in Pradis.…”

“…Note that the standard error bands are color-coded according to the isoscape ranges (see c ); local marmot enamel and Pradis 1 dentine are reported as comparison. (c) Northern Italy isoscape based on Lugli et al 52 ; several relevant archaeological sites close to Pradis are reported. …”

“…To better constrain human mobility (Fig. 4 ), an isoscape of Northern Italy was built using literature data ( https://www.geochem.unimore.it/sr-isoscape-of-italy/ ) of bioavailable Sr 52 . Specifically, geolocated 87 Sr/ 86 Sr data of plants, waters, soils (bioavailable fraction) and biominerals have been collected (n = 883) and plotted using QGIS (version 3.18).…”

We present the results of a multi-disciplinary investigation on a deciduous human tooth (Pradis 1), recently recovered from the Epigravettian layers of the Grotte di Pradis archaeological site (Northeastern Italian Prealps). Pradis 1 is an exfoliated deciduous molar (Rdm2), lost during life by an 11–12-year-old child. A direct radiocarbon date provided an age of 13,088–12,897 cal BP (95% probability, IntCal20). Amelogenin peptides extracted from tooth enamel and analysed through LC–MS/MS indicate that Pradis 1 likely belonged to a male. Time-resolved 87Sr/86Sr analyses by laser ablation mass spectrometry (LA-MC-ICPMS), combined with dental histology, were able to resolve his movements during the first year of life (i.e. the enamel mineralization interval). Specifically, the Sr isotope ratio of the tooth enamel differs from the local baseline value, suggesting that the child likely spent his first year of life far from Grotte di Pradis. Sr isotopes are also suggestive of a cyclical/seasonal mobility pattern exploited by the Epigravettian human group. The exploitation of Grotte di Pradis on a seasonal, i.e. summer, basis is also indicated by the faunal spectra. Indeed, the nearly 100% occurrence of marmot remains in the entire archaeozoological collection indicates the use of Pradis as a specialized marmot hunting or butchering site. This work represents the first direct assessment of sub-annual movements observed in an Epigravettian hunter-gatherer group from Northern Italy.
