Abstract

QUINTANA, Carlos A.. The Upper Pleistocene-Holocene record of Ctenomys talarum in EasternTandilia Range. Mastozool. neotrop. [online]. 2004, vol.11, n.1, pp.45-53. ISSN 0327-9383.

The identity of 1,004 cranial and mandibular remains of Ctenomys from the stratigraphic sequence of the archaeological site Cueva Tixi, is discussed. According to a similarity analysis based on cranial characters the studied remains belong to the species Ctenomys talarum Thomas, 1898. Their abundance, measured as a percentage of the minimum number of specimens, diminishes gradually from the Late Pleistocene of Cueva Tixi, until disappearing in historical times from the mountain area.

Keywords : Ctenomys; Tixi Cave; Tandilia; extinction; Argentina.
