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).
The hystricognaths include several lines that radiated in Africa and South America in the Oligocene and Miocene.[…]The largest hystricognath group is the Caviomorpha, the South American guinea pigs, capybaras, chinchillas and New World porcupines.
