Ile Makamby (Miocene of Madagascar)

Also known as Nosy Makamby, Makamba

Where: Madagascar (15.7° S, 45.9° E: paleocoordinates 16.0° S, 45.6° E)

• coordinate estimated from map

When: Tortonian (11.6 - 7.2 Ma)

• lower terrigenous unit and upper nummulitic marl

•Early late Miocene, about 10 Ma, or early Tortonian. For this locality, Ramihangihajason et al. (2014; see their Fig. 4, numbers 8, 15, 24) reported foraminiferal taxa and ages including: Ammonia cf. beccarii (early Miocene to Holocene), Alveolinella sp. (middle Miocene to Ho- locene), and Lepidocyclina sp. (Eocene– early Miocene).
