摘要

A tooth of a sirenian from the Late Miocene sediments of the Bahia Inglesa Formation (Chile) is described and referred to the Dugongidae. The fossil represents the first sirenian record from Chile and the southernmost record of the Sirenia in the eastern Pacific Ocean (latitude 27° S). The Chilean record extends the already wide geographical distribution of fossil sirenians along the Eastern Pacific coast. The presence of a sirenian during the Miocene on the Chilean coast is related to a globally warmer climatic condition and a still limited northern extension of the cold Humboldt Current.
