This chapter shows that other areas of the Andes (Colombia and Bolivia in particular) have also produced significant collections of Cenozoic mammals. Smaller collections have come from the Andes of Ecuador and Peru. Most of these localities are north of the Tropic of Capricorn, well outside the traditionally well-sampled southern part of the continent. The only other mammal faunas known from this vast area of South America are a handful of lowland faunas from Brazil, Peru, and Venezuela. These low and middle latitude assemblages have provided critical insights into the development of Neotropical mammal communities. They are spread over tens of millions of years; however, they provide mere glimpses of habitats and communities rather than an integrated picture of evolving mammal faunas. Sampling thus remains a key issue in Neotropical paleomammalogy, especially in light of biogeographic hypotheses that recognize Patagonia as a region distinct from the rest of South America. Documenting new fossil mammal localities in low and intermediate latitudes is a priority for future research.
