Abstract

The main goal of the present project is to explore the biogeography of Northern South America (NSA) from a paleontological perspective and the interplay of the fossil record and the interrelationships among extant taxa as a way to infer past drainage connections and their relevance for explaining the faunal relationships among drainages in NSA. This portion of the continent present several important drainages, all of them related historically to the core Amazon/Orinoco/Guyanas, but with highly endemic and poor faunas. Such high endemism and small richness seems to be the product of tectonic events that shaped both the geography and the drainages of NSA, therefore triggering speciation and extinction events in this part of the continent. The fossil record is going to be used in the present project in order to address the question of drainage connections among cis- and trans-Andean NSA during the early Pliocene, i.e., since the last 2 Ma. This work is unique in that the fossil collections herein available are largely unstudied and are crucial for understanding the tectonic and faunal evolution of NSA during the early Pliocene. In the same way, it completes the temporal record in NSA from the middle Miocene to the Pliocene, being complementary with earlier works with important fossil faunas such as La Venta in Colombia and Urumaco in Venezuela. It is expected that this work will provide a new paleogeographic framework, as well as further information to be used in molecular clock studies, that coupled with geologic information are the base for understanding the evolution of freshwater faunas in the presence of complex geological processes.
