ORTIZ, Pablo E.  and  JAYAT, J. Pablo. Fossil record of the Andean rat, Andinomys edax (Rodentia: Cricetidae), in Argentina. Mastozool. neotrop. [online]. 2007, vol.14, n.1, pp.77-83. ISSN 0327-9383.

Andinomys edax (Rodentia, Cricetidae) has a broad distribution in the Central Andean region. The fossil record is restricted to only three localities from Lower-Middle Pleistocene in Bolivia to Upper Holocene in Argentina. Recent field work in northwestern Argentina produced five new paleontological localities: Las Juntas, Catamarca (13.4 - 12.95 kyr BP); Inca Cueva 4, Jujuy (11 - 9 kyr BP); Tafí del Valle, Tucumán (10.25 - 9.75 kyr BP); Los Viscos, Catamarca (1.88 kyr bp); and La Cueva, Jujuy (0.95 kyr BP). The paleontological data indicate that A. edax has been a ubiquitous sigmodontine in northwestern Argentina since the Upper Pleistocene.

Keywords : Northwestern Argentina; Paleontological record; Quaternary.
