ResumoLiving and fossil primates present a more diverse range of locomotor behaviors than any other Order of mammals, and are therefore an ideal group for investigating the morphological bases for differences in limb use and function. This presentation focuses on recent experimental approaches, using nonprimate models, to validate methods for analyzing subchondral bone apparent density and trabecular bone that are used to infer locomotor and postural behavior in primates. Comparative data on subchondral bone apparent density are presented for a phylogenetically diverse sample of extant primates, with the goal of evaluating relationships between the location of maximal bone apparent density on the surface of the distal femur, and knee posture. The results are applied to the interpretation of locomotor behavior in two species of subfossil lemurs, Pachylemur and Hadropithecus.
