Abstract

New finds of microfloras and anuran remains from the Paleogene of the vicinity of Confluencia, northwestem Patagonia (about 40°40', 71°0.5'0), are presented. Stratigraphical and paleontological evidences suggest a relatively persistent lacustrine setting that was inhabited by pipid frogs. The surrounding vegetation included conifers and Notbofagus that grew under a mild and humid climate. However, changes in water level and in ñoristic composítion point to the occurrence of climatic f1uctuations. The recorded biota has no present day analogue.
