The present paper gives a case report on the death of a wild young chimpanzee (Pan troglodytes verus) at Bossou, Guinea. The corpse of a 6.5-year-old male was found, and an autopsy suggested that he had died from some non-epidemic disease or from poisoning. Morphological measurements of the skeleton revealed that the chimpanzee was much smaller than corresponding individuals in captivity. The dental formula of the chimpanzee coincided with those of 5- to 5.5-year-olds in captivity. The death of this chimpanzee suggests that some of the individuals who had disappeared at Bossou had died of natural causes.
