Marais de l'Ermitage (Holocene of Reunion)

Where: Reunion (21.1° S, 55.2° E: paleocoordinates 21.1° S, 55.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• The filling of the swamp consists of about 80 cm of organic soil with very few fossils. This overlies a layer 30 to 40 cm deep made up of countless bones and shell fragments of the large, extinct land-tortoise Cylindraspis borbonica Bour, mixed with volcanic rocks and blocks of coral. Several bones of Cylindraspis borbonica dated at 915 +/- 120 BP (after calibration 883-1273 AD); a bone of C. borbonica from the base of the sediment dated at 1755 +/- 40 BP (after calibration 186-391 AD); and a pig bone, introduced by humans, dated at 365 +/- 35 BY (after calibration 1458-1633 AD). The three dates obtained for the Marais de l'Ermitage indicate that the remains of tortoises, birds, and bats accumulated over a period of at least 1400 years, from about 300 AD to about 1700 AD.
