Abstract

The fossil mammal faunas of North and South America indicate that the two continents were separated from Paleocene or earlier time until the late Pliocene. Unfortunately our almost complete ignorance of the Tertiary land mammals of Central America, the geology of this large area, makes reconstruction of the Tertiary zoogeography of the region between the continents an exercise involving considerable speculation.
