Florentino Ameghino

Florentino Ameghino was an Argentine naturalist, paleontologist, anthropologist and zoologist, whose fossil discoveries on the Argentine Pampas, especially on Patagonia, rank with those made in the western United States during the late 19th century. Along with his two brothers – Carlos and Juan – Florentino Ameghino was one of the most important founding figures in South American paleontology.

From 1887 until his death, Ameghino was passionately devoted to the study of fossil mammals from Patagonia, with the valuable support of his brother Carlos Ameghino who, between 1887 and 1902, made 14 trips to that region, where he discovered and collected numerous fossil faunas and made important stratigraphic observations.
