Radiocarbon investigation of the pedunculate oak of Botosana, Romania

The article discloses the AMS (accelerator mass spectrometry) radiocarbon dating results of the pedunculate oak of Botoşana. Four wood samples were extracted from its trunk. Five segments extracted from these samples were analyzed by AMS radiocarbon. Their radiocarbon dates were found to be between 161 ± 21 BP and 260 ± 20 BP. These values correspond to calibrated ages of 235 -365 years. The dating results extrapolated to the geometric center of the trunk indicate an age of 645 ± 50 years for the oak of Botoşana.

“…Romania hosts several trees which have reached large dimensions and old ages. We investigated and dated by radiocarbon some remains of the historic oak of Ţebea [9], the large pedunculate oak of Cajvana [10], the old black poplar of Mocod and the big grey poplar of Rafaila [11], and the old ash of Aiton [12].…”

“…The oldest African baobabs were found to have ages of over 2,000 years. Thus, the African baobab becomes the longest living angiosperm [9,11,[13][14][15].…”

“…Radiocarbon dates of the 9 sample segments are listed in Table 1. The radiocarbon dates are expressed in 14 C yr BP (radiocarbon years before present, i.e., before the reference year 1950). Radiocarbon dates and errors were rounded to the nearest year.…”

“…Sample ages and errors were rounded to the nearest 5 yr. This approach was used for selecting calibrated age ranges and single values for sample ages in all our previous articles on AMS radiocarbon dating of large and old angiosperm trees, especially of baobabs [6][7][8][9][10][11][12][13][14][15][17][18][19]. Dating results of samples (segments).…”

The article discloses the accelerator mass spectrometry (AMS) radiocarbon dating results of the Big Reniala of Isosa, which is a massive Grandidier baobab (Adansonia grandidieri Baill.) of Madagascar. The investigation of this baobab shows that it consists of 5 perfectly fused stems and exhibits a cluster structure. The calculated wood volume of the tree is 540 m 3 , which makes the Big Reniala of Isosa the largest individual of all Adansonia species and also the biggest known angiosperm in terms of volume. Several samples were collected from the outer part of the stems. The oldest dated sample had a radiocarbon date of 934 ± 24 BP, which corresponds to a calibrated age of 845 ± 25 years. This value indicates an age of 1000 ± 100 years for the big Reniala of Isosa.

The article reports the AMS (accelerator mass spectrometry) radiocarbon investigation results of the old common ash of Aiton. Five wood samples were collected from the trunk of the tree. The deepest ends of the samples were analysed by AMS radiocarbon. We found radiocarbon dates between 165 ± 20 BP and 240 ± 18 BP, which correspond to calibrated ages of 230-360 years. These results, combined with a ring counting estimate, indicate an age of 330 ± 30 years for the ash of Aiton. By this value, the ash of Aiton becomes the oldest known common ash with accurate dating results.
