Barium distributions reveal natural and truncated weaning (black arrows) in macaque molars. Left: natural weaning after 296 days. Center: weaned slightly early due to maternal separation at 257 days. Right: markedly shortened weaning due to maternal separation at 166 days. Four dietary regions are apparent for each: 1. prenatal, 2. exclusive mothers’ milk, 3. transitional period, and 4. post-weaning. The enamel-dentine junction is indicated with a dashed line.
