 Several other mammals have been recorded from the late Cretaceous of Madagascar, mostly on the basis of isolated teeth. A possible second gondwanathere is represented by a tooth that is larger and lower-crowned than those of Lavanify, and a yet lower-crowned tooth may also be of a gondwanathere. A lower molar, UA 8699, may be of a marsupial or a placental and a molar fragment is referable to Multituberculata. Finally, an as-yet-undescribed mammal is known from a fairly complete skeleton. None of these mammals is related to the living mammals of the island, many of which belong to unique groups (see List of mammals of Madagascar). The fauna also contains crocodyliforms, dinosaurs, and other animals.
