Several wood samples collected from Dorslandboom, a large African baobab (Adansonia
digitata L.) from Namibia, were investigated by AMS radiocarbon dating subsequent to
pretreatment and, alternatively, without pretreatment. The comparative statistical
evaluation of results showed that there were no significant differences between fraction
modern values and radiocarbon dates of the samples analyzed after pretreatment and
without pretreatment, respectively. The radiocarbon date of the oldest sample was 993 ± 20
BP. Dating results also revealed that Dorslandboom is a multi-generation tree, with several
stems showing different ages.
