Elephant bird The bones of these domesticated fowl have been found in subfossil sites in the island (MacPhee and Marx, 1997: 188), such as Ambolisatra (Madagascar), where "Mullerornis" sp. and "Aepyornis maximus" have been reported. Also reported by these authors, ratite remains have been found in west and south west Madagascar, at Belo-sur-Mer ("A. medius", "Mullerornis rudis"), Bemafandry ("M. agilis") and Lamboharana ("Mullerornis" sp.).
