A new Mesembriornithinae (Aves, Phorusrhacidae) provides new insights into the phylogeny and sensory capabilities of terror birds
(Society of Vertebrate Paleontology, 2015-03)
Terror birds constitute the most outstanding group of the South American Cenozoic avifauna. Considered as apex predators, their hunting skills have recently been examined, but their diversity is still unresolved. Here we ...

Tamaño y estimación de la masa corporal en Procariama simplex Rovereto, 1914 (Aves: Phorusrhacidae: Psilopterinae)Size and body mass in Procariama simplex Rovereto, 1914 (Aves: Phorusrhacidae: Psilopterinae)
(Asociacion Paleontologica Argentina, 2012-10)
La masa corporal de ejemplares de aves fósiles puede ser estimada mediante comparaciones con las formas actuales, teniendo en cuenta que las medidas del fémur, el tibiotarso y el tarsometatarso son indicadoras del peso del ...
