Aging mountain gazelle (Gazella gazella): refining methods of tooth eruption and wear and bone fusion

This paper refines current methods for aging mountain gazelle (Gazella gazella), one of the most common species hunted by prehistoric humans in the southern Levant. Most importantly, we present a new tooth wear scheme for aging the lower deciduous fourth premolar (dP4), the lower permanent molars (M1, M2, M3) and the lower fourth premolar (P4) of the gazelle. Broader wear stages for complete mandibles and individual teeth and bone fusion stages are also provided. Finally, a comparison of the tooth wear and bone fusion data indicates that the two methods can be linked at the important transition when a gazelle reaches adulthood (ca. 18 months of age). The completion of the fusion of the gazelle skeleton corresponds directly to the replacement of the dP4 by the P4 and the beginning of wear of the M3. The coincidence of these aging indicators allows for direct comparison of gazelle bone fusion and tooth wear data.
