When I found in La Plata the tooth of a horse embedded with the remains of Mastodon, Megatherium, Toxodon, and other extinct monsters, which all co-existed with still living shells at a very late geological period, I was filled with astonishment; for seeing that the horse, since its introduction by the Spaniards into South America, has run wild over the whole country and has increased in numbers at an unparalleled rate, I asked myself what could so recently have exterminated the former horse under conditions of life apparently so favourable.
We may doubt whether they have thus changed: if the Megatherium, Mylodon, Macrauchenia, and Toxodon had been brought to Europe from La Plata, without any information in regard to their geological position, no one would have suspected that they had coexisted with still living sea-shells; but as these anomalous monsters coexisted with the Mastodon and Horse, it might at least have been inferred that they had lived during one of the latter tertiary stages.
Lastly, the Toxodon, perhaps one of the strangest animals ever discovered: in size it equalled an elephant or megatherium, but the structure of its teeth, as Mr.
Finally, I will assuredly give some account of the toxodon, the giant ten-foot guinea pig, with projecting chisel teeth, which we killed as it drank in the gray of the morning by the side of the lake.

Asi fue como en Punta Alta y en la Patagonia, Darwin encontro 9 restos fosiles de animales gigantes extinguidos: tres cabezas y huesos de Megatherium; un Megalonyx; un esqueleto casi completo de Scelidotherium, que debio ser tan grande como un rinoceronte; un Mylodon Darwinii, un poco menor que el anterior; un desdentado gigantesco; una caparazon de un animal gigantesco muy parecido al armadillo; una especie extinta de caballo; un diente de un paquidermo, el Macrauchenia, notable cuadrupedo tan grande como un camello; un Toxodon, uno de los animales mas extranos que se hayan descubierto jamas, parecido al elefante (Darwin, 1845/1983, ver capitulos V y VI).

This fascinating section includes specimens critical to his work, such as the original fossil skull of a large hoofed mammal, Toxodon platensis, which he collected on his expedition and later discussed with colleagues.
