The Greater Rhea (Rhea americana, Rheidae) is a flightless paleognath with a wide geographical distribution in South America. The morphology of its shoulder girdle and wings are different from those of flying birds and some characteristics are similar to basal birds and paravian theropods. We present a detailed osteological, myological, and functio...

In 1976 John Ostrom published an enlightening paper about the anatomical transformations in the shoulder girdle and forelimb elements along the origin of birds. Most of his ideas were based on comparing Archaeopteryx lithographica with the extant New World vulture Cathartes aura. Ostrom offered innovative ideas about range of movements and function...

Discussions about the origin of flight almost unanimously assume that early birds positioned (and moved) their wings in the same basic manner as living flying birds, with reconstructed wings extended with the airfoil surface parallel to the ground and forelimbs moving in a dorsoventral arc. Such reconstructions of wing posture and movements for ext...

The fossil record of owls of the families Strigidae and Tytonidae in South America is poor. The aim of the present contribution is to report for the first time fossil Strigiformes from Riobamba Canton, at Chimborazo province, in Ecuador. The specimens come from a large owl burrow from Late Pleistocene beds of the Cangagua Formation. We report the f...

Barn Owls (Tytonidae) are nocturnal raptors with the largest geographical distribution among Strigiformes. Several osteological, morphometrical, and biomechanical studies of this species were performed by previous authors. Nevertheless, the myology of forelimb and tail of the Barn Owls is virtually unknown. This study is the first detailed myologic...

The first fossil remains of vertebrates, invertebrates, plants and palynomorphs of the Chorrillo Formation (Austral Basin), about 30km to the SW of the town of El Calafate (Province of Santa Cruz), are described. Fossils include the elasmarian (basal Iguanodontia) Isasicursor santacrucensis gen. et sp. nov., the large titanosaur Nullotitan glaciari...

En aves voladoras actuales el músculo supracoracoides recorre hacia arriba la cara anteromedial del coracoides, rodea al proceso acrocoracoidal y atraviesa el foramen trióseo para finalmente insertarse sobre la cara dorsal del húmero. Su función es clave en la elevación del ala y la rotación longitudinal del húmero. John Ostrom describió la condici...

Recent years witnessed the discovery of a great diversity of early birds as well as closely related non-avian theropods, which modified previous conceptions about the origin of birds and their flight. We here present a review of the taxonomic composition and main anatomical characteristics of those theropod families closely related with early birds...

El pingüino barbijo Pygoscelis antarctica es una de las tres especies de pingüinos pygoscélidos que reproduce en la Península Antártica e islas al sur de la convergencia antártica. En las islas Shetland del Sur las poblaciones reproductivas han declinado en los últimos años. Específicamente en Punta Stranger (Isla 25 de Mayo), al final de la década...

Resumen Holochilus chacarius Thomas, 1906 (Mammalia, Rodentia, Sigmodontinae) in Middle Delta of the Paraná River, Entre Ríos, Argentina. We describe the presence of Holochilus chacarius in the Victoria Island Zone included in the Middle Ddelta of the Paraná Rriver (Entre Rríos, Argentina). We collected and analysed pellets of the Striped Oowl (Ps...

We describe the presence of Holochilus chacarius in the Victoria Island Zone included in the Middle Delta of the Paraná River (Entre Ríos, Argentina). We collected and analysed pellets of the Striped Owl (Pseudoscops clamator). All cranio dental items that were identified and measured belong to the Chaco Marsh Rat. We postulate that its occurrence...
Article
Se evaluó el estado de situación y el efecto de disturbios naturales y antrópicos sobre la comunidad de aves de los humedales de la Zona de Islas del Departamento Victoria (ZIDV, Entre Ríos). En ella tradicionalmente se realizaba “ganadería de isla” pero, en los últimos años, la carga animal y su permanencia aumentaron dramáticamente. Durante el añ...

The aim of this project is to document the anatomy and evolution of South American Paravian fossil record, mostly represented by unenlagiids. The phylogenetical relationships of these theropods are far from being understood. In this way detailed anatomical studies of their members could help clarify their relationships among paravians.
