Cyonasua zettii

Cyonasua zettii is an extinct member of the raccoon family, Procyonidae, formally named in 2023 by Hontecillas and colleagues from fossils found in central Argentina. The Paleobiology Database records it as an extinct, terrestrial and actively mobile mammal whose fossil range runs from the Tortonian stage into the Zanclean, roughly eight to five million years ago, and it lists two fossil occurrences, both in La Pampa Province, in levels of the Cerro Azul Formation. The database gives it a scansorial way of life and a mixed diet of fruit and meat, but it takes both from the family as a whole rather than from the animal itself, so they are family level inferences. The species belongs to the genus Cyonasua, whose members were among the first carnivorans to reach South America.
