Garber, Gabriel Marroig, “Chapter 3: Paleogeography of the South Atlantic: a Route for Primates and Rodents into the New World?”, in 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).
- 2009, Michael J. Benton, Vertebrate Palaeontology[1], page 359:
- 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.
