%X Objectives: Existing data on bonobo and chimpanzee dental eruption timing are<br>derived predominantly from captive individuals or deceased wild individuals. How-<br>ever, recent advances in noninvasive photographic monitoring of living, wild apes<br>have enabled researchers to characterize dental eruption in relatively healthy individ-<br>uals under naturalistic conditions. At present, such data are available for only one<br>population of wild chimpanzees. We report data for an additional population of wild<br>chimpanzees and the first dental eruption data for wild bonobos.<br>Materials and Methods: We collected photographs and video footage of teeth from<br>the open mouths of wild bonobos and East African chimpanzees of known age from<br>LuiKotale, Democratic Republic of the Congo, and Gombe National Park, Tanzania,<br>respectively. We scored the presence and absence of deciduous teeth from photo-<br>graphs and video footage to characterize deciduous dental eruption timing in these<br>two populations.<br>Results: Deciduous dental eruption ages in our sample fall within the range of varia-<br>tion previously documented for captive chimpanzees, but eruption ages are later in<br>wild than in captive contexts. We found substantial variation in deciduous canine<br>eruption timing, particularly among bonobos. One bonobo had a deciduous canine<br>present by 227 days old while another did not have a deciduous canine present at<br>477 days old.
