Radiocarbon Date

An assemblage of 366 lithics was recovered during the characterisation of archaeological deposits, from deposits which appear to represent a scooped occupation. Analysis of the assemblage and a radiocarbon date range of 6355-6012 cal BC indicate that it belongs to the Mesolithic. The site is significant because it is the first Mesolithic material to have been recovered by excavation in the Girvan area. It also provides additional evidence for a class of semipermanent Mesolithic sites consisting of shallow scoops surrounded by turf or earthen banks.

Early Agriculture

Excavations near two upstanding hut circles overlooking Machrie Moor revealed traces of early agriculture in the form of narrow, or 'cord' rig associated with a small cairn. Sealed beneath this were traces of earlier agricultural activity in the form of ard marks. A radiocarbon date from a basal sample of the overlying peat spanned the fifth to seventh centuries AD.

The volcanic Comoro Islands, located in the Indian Ocean in between mainland Africa and Madagascar, host several thousand African baobabs (Adansonia digitata). Most of them are found in Mayotte, which currently belongs to France, as an overseas department. We report the investigation of the largest two baobabs of Mayotte, the Big baobab of Musical Plage and the largest baobab of Plage N’Gouja. The Big baobab of Musical Plage exhibits a cluster structure and consists of 5 fused stems, out of which 4 are common stems and one is a false stem. The baobab of Plage N’Gouja has an open ring-shaped structure and consists of 7 partially fused stems, out of which 3 stems are large and old, while 4 are young. Several wood samples were collected from both baobabs and analyzed via radiocarbon dating. The oldest dated sample from the baobab of Musical Plage has a radiocarbon date of 275 ± 25 BP, which corresponds to a calibrated calendar age of 365 ± 15 yr. On its turn, the oldest sample from Plage N’Gouja has a radiocarbon date of 231 ± 20 BP, which translates into a calibrated age of 265 ± 15 yr. These results indicate that the Big baobab of Musical Plage is around 420 years old, while the baobab of Plage N’Gouja has an age close to 330 years. In present, both baobabs are in a general state of deterioration with many broken or damaged branches, and the Baobab of Plage N’Gouja has several missing stems. These observations suggest that the two baobabs are in decline and, most likely, close to the end of their life cycle.
