Description:
The article reports the AMS (accelerator mass spectrometry)
radiocarbon dating results of Sagole Big tree, a giant African baobab from
Limpopo, South Africa. Several wood samples were collected from the walls
of its inner cavity and dated by radiocarbon. The age values along the cavity
samples increase with the distance into the wood. This anomaly shows that
the cavity is a false one. The oldest sample segment had a radiocarbon date
of 781 ± 29 BP, which corresponds to a calibrated age of 740 ± 15 yr. We
estimate that the oldest part of the Sagole baobab has an age of 800-900 yr.
We determined that the tree has a closed ring-shaped structure, which
consists of a large unit with six fused stems and of two additional leaning
stems.
