 Lavanify is a mammalian genus from the late Cretaceous ( probably Maastrichtian , about 71 to 66 million years ago ) of Madagascar . The only species , L. <unk> , is known from two isolated teeth , one of which is damaged . The teeth were collected in 1995 – 1996 and described in 1997 . The animal is classified as a member of Gondwanatheria , an enigmatic extinct group with unclear phylogenetic relationships , and within Gondwanatheria as a member of the family Sudamericidae . Lavanify is most closely related to the Indian Bharattherium ; the South American Sudamerica and Gondwanatherium are more distantly related . Gondwanatheres probably ate hard plant material .
