The age and sex determination of the individuals are based on international standardized methods [23]. The denotation of the teeth follows the two-digit-system of the World Dental Federation. The investigated key feature, the maxillary lateral incisor agenesis (MLIA), has three possible outcomes: presence (+), absence (–), or the trait is indiscernible (?) because the upper jaw itself is missing. The column ‘microdontia or other agenesis’ comprises maxillary lateral incisors with reduced size and/or other types of missing teeth. MLIA and microdontia represent a variable expression of the same developmental defect. Other types of teeth such as the premolars 35 and 45 can additionally be missing [26]. Only three individuals have Sr-isotope values clearly outside the local average 87Sr/86Sr. Analytical methods for Sr-isotope analysis follows [29] with minor modifications.
