Two wood samples were collected from the large inner cavity. Several segments were extracted from these samples ams c14 dating analysed by AMS accelerator mass spectrometry radiocarbon dating. We found that the age values of segments increase with the distance into the wood.
This major anomaly is characteristic to multi-stemmed baobabs with a closed ring-shaped structure and a false cavity inside. The investigation of the Humani Bedford baobab evinced that the baobab consists of three fused stems.
The fourth stem of the ring is missing.
The oldest dated segment was found to have a radiocarbon date of ± 14 BP, which corresponds to a calibrated age of ± 30 yr. The dating results show that the stems which build the ring stopped growing toward the false cavity more than yr ago. By considering the position of the oldest segment in the investigated stem, we concluded that the Humani Bedford baobab is around yr old.
According to our dating results, the Humani Bedford baobab becomes the oldest living African baobab. Keywords: AMS radiocarbon dating, Adansonia digitata, tropical trees, dendrochronology, age determination.
