     The New World hystricognath rodents (= caviomorphs) today represent one of the most diverse and widespread suborders among the over 800 mammal species of South America (Woods, 1982).

Garber, Gabriel Marroig, Chapter 3: Paleogeography of the South Atlantic: a Route for Primates and Rodents into the New World?, Alejandro Estrada, Julio Cesar Bicca-Marques, Eckhard W. Heymann, Karen B. Strier (editors), South American Primates, page 63,

     The situation is similar with respect to rodents, given that the earliest undisputed hystricognaths are from the Oligocene of Pakistan and Egypt (ca. 35Ma), with the possibility of a Middle Eocene origin for the group (Bryant and McKenna 1995; Marivaux et al. 2002).
