Mobility of the Middle-Upper Paleolithic infants via time-resolved ⁸⁷Sr/⁸⁶Sr profiles of their deciduous teeth. Gray horizontal bands represent the local Sr isotopic baselines defined via the Sr isotopic composition of archaeological rodent enamel (SI Appendix, Table S1). The birth event is indicated by a vertical line. (A and B) Nadale 1/Fumane 1: exploitation of local food resources through the entire period; (C) Riparo Broion 1: possible limited seasonal mobility (nonlocal values between ca. −45 and 85 d, ∼4 mo); (D) Fumane 2: exploitation of nonlocal food resources through the entire period.
