Se lista y comenta el registro de aves fósiles de Chile Continental. El registro más antiguo corresponde al gaviforme fósil Neogaeornis wetzeli Lambrecht, 1929, proveniente de Formación Quiriquina (Maastrichtiano superior). Las aves paleógenas registradas hasta el momento provienen de los Estratos de Algarrobo, Región de Valparaíso y de las formaci...

Three specimens of elasmosaurid plesiosaurs (Sauropterygia, Plesiosauria) from Upper Cretaceous beds of Antarctica are described here. These include postcranial remains of a single adult individual recovered from late Maastrichtian beds of Marambio (=Seymour) Island, possessing a distinctive combination of features: cervical vertebrae having centra...

We present new records of chondrichthyans recovered from strata of Maastrichtian age of the Lopez de Bertodano Formation, Seymour (=Marambio) Island, and from levels of latest Campanian age of the Santa Marta Formation, James Ross Island, both located in the eastern Antarctic Peninsula. The material from Marambio Island comprises an associated asse...

We describe a new chimaeriform fish, Callorhinchus torresi sp. nov., from the uppermost Cretaceous (late Maastrichtian) of the López de Bertodano Formation, Isla Marambio (Seymour Island), Antarctica. The material shows it is distinct from currently known fossil and extant species of the genus, whereas the outline of the tritors (abrasive surfaces...

Paleogene records of birds in the Eastern margin of the Pacific Ocean have increased in recent years, being almost exclusively restricted to fossil Sphenisciformes (penguins). New avian remains (Ornithurae, Neornithes) from Middle-to-Late Eocene levels of the Estratos de Algarrobo unit, in Algarrobo, central Chile, are disclosed in the present work...

We present new data on the paleoichthyology, paleobotany and radiometric results of the Loreto Formation in the Brunswick Peninsula of southernmost Chile, that allow us to propose a Late Eocene age. The rich diversity of fossil cartilaginous fishes (Chondrichthyes, Elasmobranchii) recognized in upper levels of this unit includes the taxa Carcharias...

El registro de aves fósiles en Chile se ha incrementado en forma notable en los últimos años. Las localidades abarcan desde el Cretácico Superior al Neógeno, con representantes de nueve familias. Los hallazgos más recientes corresponden al Eoceno tardío de la Región de Magallanes, donde se han reconocido múltiples restos fragmentarios de Spheniscif...

This study presents the first record of Eocene birds from the western margin of southernmost South America. Three localities in Magallanes, southern Chile, have yielded a total of eleven bird remains, including Sphenisciformes (penguins) and one record tentatively assigned to cf. Ardeidae (egrets). Two different groups of penguins have been recogni...

La Formación Bahía Inglesa en la Región de Atacama, es reconocida como la formación de mayor abundancia en vertebrados fósiles cenozoicos, registros que incluyen cocodrilos, sirenios, cetáceos, pinnípedos, tiburones y aves. Estas últimas se encuentran representadas por 6 familias: Pelagornithidae, Phalacrocoracidae, Sulidae, Spheniscidae, Diomedeid...

The lack of osteological studies in birds and the absence of certain taxa in different osteological collections of the country, in contrast to the notable increase in the records and descriptions of fossil birds, they make necessary a review of the state of the collections of birds skeletons in Chile. This with the purpose of determining the signif...
