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 co-existed with sea-shells all still living; but as these anomalous monsters co-existed with the Mastodon and Horse, it might at least have been inferred that they had lived during one of the later tertiary stages.
Megatherium, Mylodon, Macrauchenia eta Toxodon-a La Platatik Europara beren kokaera geologikoari buruzko inolako informaziorik gabe ekarri balira, inork ere ez zukeen susmatu egun ere bizirik dirauten moluskuekin denbora berean existitu zirenik; baina munstro anomalo hauek mastodonte eta zaldiarekin aldi berean existitu zirenez gero, inferitu behintzat egin zitekeen tertziarioko azken estratuetako batean bizi izan zirela.
