About Lavanify in brief

Summary LavanifyLavanify is a mammalian genus from the late Cretaceous of Madagascar. The only species, L.  miolaka, is known from two isolated teeth, one of which is damaged. The animal is classified as a member of Gondwanatheria, an enigmatic extinct group with unclear phylogenetic relationships. Lavanify had high-crowned, curved teeth. Several other gondwanatheres have been recorded from the same time period. A lower molar fragment of a marsupial may be also be a gondwansathere, UA99, UA8699, may be a lower molar and a placental fragment is an-yet-undescribed Multituberculata, as well as an unnamed species from the Eocene of Antarctica.

The generic name, Lavanifying, means ‘long tooth’ and the specific name, miolaka,. means ‘curved’ in Malagasy; both refer to the teeth’s shape. The two teeth were found in different sites in a white sandstone unit of the Maevarano Formation near the village of Berivotra and have been deposited in the collections of the University of Antananarivo and Field Museum of Natural History. These were the first gondwanaathere mammals to be found outside of Argentina and provided evidence that the mammal faunas of the different Gondwanaan continents were similar to each other. The species may be the earliest grass-eating mammals.
