Nevertheless, looking to a remotely future epoch, there can be little doubt that all the more modern MARINE formations, namely, the upper pliocene, the pleistocene and strictly modern beds of Europe, North and South America, and Australia, from containing fossil remains in some degree allied, and from not including those forms which are found only in the older underlying deposits, would be correctly ranked as simultaneous in a geological sense.
Hala ere, etorkizun urrunera begiratuz, ia dudarik ez dago itsas ekoizkin modernoenak, hau da, pliozeno eta pleistozenoko geruzak eta Europa, Ipar eta Hego Amerika eta Australiako geruza hertsiki modernoak, adiera gelogikoan, aldi berekotzat egokiro sailkatuko liratekeela, hondakin fosil nolabait ahaideak dauzkatelako eta behealdeko metaketa zaharragoetan topatzen den formarik ez daukatelako.
