In South America, a similar relationship is manifest, even to an uneducated eye, in the gigantic pieces of armour, like those of the armadillo, found in several parts of La Plata; and Professor Owen has shown in the most striking manner that most of the fossil mammals, buried there in such numbers, are related to South American types.
Hego Amerikan ere antzeko ahaidetasuna nabari da, aritua ez den begiarentzat ere, La Platako alde ezberdinetan aurkituriko armadiloarenak bezalako oskol pieza erraldoietan; eta Owen irakasleak erarik nabarmenenean frogatu du han lurperaturik ugari dauden ugaztun fosilik gehienak Hego Amerikako tipoen ahaideak direla.
