Geographic Range [top]

Range Description: Mascarenachen kervazoi is known only from subfossil bones collected by Bertrand Kervazo in the Grottes des Premiers Français on Réunion (to France) in 1974 (Cowles 1994). Nontekoe mentioned finding geese on the island when he visited in 1619, as did Dubois in 1671-2, but it was not to persist long and the species was specifically mentioned to have become extinct by Boucher in 1710 (Cheke 1987). The specimens are deposited in the Muséum National d'Histoire Naturelle, Paris (Cowles 1994).
