Capybaras (Hydrochaeris hydrochaeris)

[Polar]

Neochoerus pinckneyi

"Neochoerus pinckneyi was a North Americanspecies of capybara. While capybaras originated in South America, formation of the Isthmus of Panama three million years ago allowed some of them to migrate north as part of the Great American Interchange. Capybaras and porcupines are the only caviomorph rodents that reached temperate North America during this exchange (a much greater diversity of North American rodents invaded South America). At 90 to 113 kg (200 to 250 pounds), 40% larger than the living capybara,[1] N. pinckneyi is one of the largest rodent species ever discovered, surpassed only by the recently discovered Josephoartigasia monesi, several species of Phoberomys, and possibly the Pleistocene giant beaver."

There was a North American relative too. One question is, though, on which continent did capybaras originate from? Reply
