Cyonasua is an extinct procyonid genus from the Late Miocene to Late Pliocene of Argentina (Ituzaingó, Epecuén, Huayquerías and Cerro Azul Formations) and Venezuela (San Gregorio Formation), South America (7.3[1] to 3 million years ago).[2] Its name in Greek means dog-coati because its features resemble those of a dog and a coati. Its ancestors likely arrived from Central America by island hopping, as perhaps the earliest southward mammalian migrants of the Great American Interchange. Its predators were terror birds and carnivorous metatherians. It possibly evolved into the bear-like Chapalmalania.
