Also known as Reef 3806

Where: Seychelles (9.4° S, 46.4° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Aldabra Limestone Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• 125 000 years (Thompson and Walton 1972)

Environment/lithology: perireef or subreef; limestone

• submerged, shallow, coral-covered bank

Size class: macrofossils

Collected in 1969; reposited in the BMNH

• June-September 1969, small additional quantity in 1973 m altogether 300 specimens
