Abstract

The Neogene record of the extinct family Pelagornithidae is examined in the Pisco Formation (Peru) and Bahia Inglesa (Chile) Formations along the Pacific coast of South America. New specimens belonging to the genus Pelagornis are reported; these come from the Sacaco and Aguada de Lomas levels of the Pisco Formation and from the phosphatic level of the Bahia Inglesa Formation. In addition new cranial and postcranial elements of uncertain genus are discussed from the Montemar level of the Pisco Formation and the base of the same Formation at the limit of the Cerro la Bruja level and the Chilcatay Formation. The present record is compared with previously known antecedents for the family in the southern hemisphere. The taxonomic problems of the group and the correct assignment of fossil elements to the family are discussed. The current knowledge of the Neogene avian record with in the study area is commented upon
