Radiocarbon dating woods hole
The Senegalese baobab of Samba Dia, which has the largest known false cavity (18 m The research is based on our new approach which allows to investigate and date standing and live specimens.
This methodology consists of AMS radiocarbon dating of small wood samples collected especially from inner cavities, but also from deep incisions/entrances in the stems and from the outer part of large baobabs.
According to radiocarbon dating results the outermost rings were around 410 yr old.
The vast majority of large and old African baobabs are multi-stemmed.
Height 18.5 m, circumference at breast height 21.44 m, overall wood volume 220 m. 2) was the first specimen for which we identified the most enigmatic baobab architecture, i.e., the closed ring-shaped stucture with a false cavity inside.
Here we present the AMS dating results of three large African baobabs, namely Holboom (Nyae Nyae Conservancy, Namibia), Luna tree (Mapungubwe National Park, South Africa) and the baobab of Samba Dia (Senegal).
The age sequences of samples collected from all these individuals show the characteristic anomalies of baobabs with false inner cavities.
Ocean sediment C-14 data The Lamont-Doherty Earth Observatory of Columbia University has compiled 974 C-14 dates from 309 ocean sediments cores, covering the period from 40,000 years BP to the present worldwide. The USGS Bear Lake Project aims to create records of past climate change for the Bear Lake region,including changes in precipitation patterns during the last 10,000 years and how the size of Bear Lake has varied in the past, to assess the possibility of future flooding and drought.
Several chronological anomalies were observed for the first time in the radiocarbon investigation of wood samples collected from the large inner cavity and from the outer part of an old African baobab (Adansonia digitata L.), i.e., the Lebombo Eco Trail tree (Mozambique).
