Cyonasua
''Cyonasua'' is an extinct procyonid genus from the late Miocene of South America (7.3 to 5 million years ago). 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 evolved into the bear-like ''Chapalmalania''. ==References==
