Extinct genus of rodents
Eoviscaccia is an extinct
genus of
chinchillid
rodent that lived during the
Early Oligocene (
Tinguirirican ) to the Early Miocene (
Colhuehuapian ) in what is now
South America . Fossils of this genus have been found in the
Cerro Bandera ,
[1]
Chichinales ,
[2]
Fray Bentos ,
[3] and
Sarmiento Formations
[4]
[5]
[6] of
Argentina , the
Salla Formation of
Bolivia ,
[6] and the
Abanico Formation of
Chile .

Taxonomy
Eoviscaccia was first described by
María Guiomar Vucetich in 1989 based on remains found in the Salla Formation of Bolivia and the Sarmiento Formation of
Chubut Province , Argentina, with the proposed type species being Eoviscaccia boliviana .
[6] Two other species, E. australis and E. frassinettii , were both named in 1989 and 2012 respectively, with E. australis being found in Chubut,
Entre Ríos ,
Neuquén , and
Río Negro Provinces of Argentina, while E. frassinettii was found in the Abanico Formation of Chile.

The following cladogram of the
Caviomorpha is based on Busker et al. 2020, showing the position of Eoviscaccia .
