"The present state of knowledge of the Cenozoic birds of Argentina" by Tonni 1980: four decades after
Publicación Electrónica de la Asociación Paleontológica Argentina 23: 255–295

“The present state of knowledge of the Cenozoic birds of Argentina” published in Contributions in Sciences in 1980, written by the argentine paleontologist Eduardo Pedro Tonni, became a must-read for those interested in the record of fossil birds. In that work, all the records known up to that time are compiled and some comments are made. Since then, there have been crucial advances in unraveling the diversity of Cenozoic birds in Argentina. Based on that work, here is a detailed updated and annotated list of all known avian records in Argentina that includes representatives of Palaeognathae (Tinamiformes and Rheiformes), Galloanseres (Anseriformes) and Neoaves (Sphenisciformes, Suliformes, Charadriiformes, Phoenicopteriformes, “Ciconiiformes”, “Gruiformes”, Pelecaniformes, Coraciimorphae, Cathartiformes, Accipitriformes, Falconiformes, Cariamiformes and Passeriformes). Besides, a substantial contribution is that here are photographs of the holotypes of all the new species that were nominated after Tonni's work and a table that compiles the main bibliographic information referring to the systematic history of each taxon.
 
As far as I can see there is one interesting taxonomic difference with earlier taxonomies.

Genus Oressochen Bannister, 1870

Type species. Oressochen jubatus (Spix, 1825). Recent, eastern South America.

Oressochen debilis (Ameghino, 1891) comb. nov.

Holotype. Lost (Mones, 1986; Agnolín, 2006a), tarsometatarsus.

Geographic and stratigraphic occurrence. La Plata City, Buenos Aires Province, Late Pleistocene, Belgrano Formation.

Comments. This species was previously included in Neochen Oberholser, 1918. However, the South American Classification Committee SACC proposed that Neochen be replaced by Oressochen (Proposal 637).
