Physornis
Physornis is an extinct genus of giant flightless predatory birds of the family Phorusrhacidae or "terror birds", most closely related to Paraphysornis, that lived in Argentina. The type species is P. fortis. It lived during the Middle to Late Oligocene (Deseadan). Few fossils are known, but the available material suggests that Physornis was one of the largest phorusrhacids. The holotype of Physornis (BMNH-A583) is a 137 mm long portion of a symphysis and the right branch of this lower jaw, described in 1894 by paleontologist Florentino Ameghino.
Devincenzia
Devincenzia is an extinct genus of giant flightless predatory birds in the family Phorusrhacidae or "terror birds" that lived during the Early Miocene (Deseadan) Fray Bentos Formation of Uruguay and Late Miocene (Huayquerian) Ituzaingó Formation to Early Pliocene (Montehermosan) of Argentina. The type species D. pozzi was formerly known as Onactornis pozzi. It stood about tall, making it one of the largest Phorusrhacids and carnivorous birds known.
Titanis
Titanis (for the mythological Greek Titans) is a genus of phorusrhacid ("terror birds", a group originating in South America), an extinct family of large, predatory birds, in the order Cariamiformes (an order including phorusrhacids and the extant seriemas) that inhabited the United States during the Pliocene and earliest Pleistocene. The first fossils were unearthed by amateur archaeologists Benjamin Waller and Robert Allen from the Santa Fe River in Florida and were named Titanis walleri by ornithologist Pierce Brodkorb in 1963, the species name honoring Waller.
Andalgalornis
Andalgalornis is a genus of flightless predatory birds of the extinct family Phorusrhacidae (often called "terror birds") that lived in Argentina. The type and only species is A. steulleti. Andalgalornis is known from an incomplete skeleton and some single bones found from sites in the Entre Ríos and Catamarca Provinces of northeast and northwest Argentina. The fossils were uncovered from the Late Miocene (Huayquerian in the SALMA classification) Ituzaingó Formation of the Paraná Basin.
