Resumen:
The first fossil records of the anseriform Chloephaga picta (Magellan Goose) and the gruiform Cariama cristata (Seriema) are described from the Sopas Formation (Late Pleistocene, northern Uruguay). According to the modern requirements of Chloephaga picta, its presence in the Sopas Formation would indicate: 1) a seasonal climate and 2) temperatures likely lower than those previously reported based on mammals. It could have occurred in response to rapid and short climatic changes with a drop of temperature not revealed by mammals. Cariama cristata is more euryoic than Chloephaga picta and suggests open woodlands, savannas and hilly grasslands with nearby woods coincident with the presence of some mammals also recorded from the Sopas Formation.
