Fossil Cetacea (Mammalia, Odontoceti, Eurhinodelphinoidea, Inioidea, Physeterioidea) of the Curré Formation, Upper Miocene (early-late Hemphillian) of Costa Rica

Abstract

Four new records of Odontoceti are described for the Upper Miocene of Southern Central America; these founds suggest a strength sea connection between the North Atlantic Coast of Europe, the Coastal Plain of North America with the tropical East Pacific Ocean. On the other hand, the fossil record of the river dolphin Goniodelphis sp., shows an important affinity between the ancient coastal wetlands of Florida and the epicontinental sediments of the Curré Formation at Costa Rica.
