About Incamys
Incamys is an extinct genus of chinchillid rodent that lived during the Late Oligocene (Deseadan) in what is now South America. Fossils of this genus have been found in the Salla Formation of Bolivia and the Agua de la Piedra and Sarmiento Formations of Argentina. Research on endocasts suggest they were group living using call communication like modern chinchillas.
