The evolutionary history of south american seabirds through the fossil record

Abstract

The fossil record of penguins (Sphenisciformes), albatrosses and petrels (Procellariiformes), cormorants and boobies (Suliformes), diving ducks (Anseriformes), and pseudo-toothed birds (Pelagornithidae) is particularly abundant on the Atlantic and Pacific coasts of South America. In addition to these are other taxa, which, although less represented, contribute to analyzing the dynamics of marine communities and reconstructing past ecosystems. This work provides an update of the fossil record of each of these groups of seabirds, including mainly Cenozoic forms but also some Cretaceous records. From this analysis, in a regional geotectonic context different from the current one, a series of hypotheses emerges that explains the main speciation and diversification processes, and the colonization and extinction events that each of these groups would have experienced before reaching their current configurations.
