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''. Taxonomy ''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. at .org The following |
Psilopterinae
Phorusrhacids, colloquially known as terror birds, are an extinct clade of large carnivorous flightless birds that were one of the largest species of apex predators in South America during the Cenozoic era; their conventionally accepted temporal range covers from 62 to 0.1 million years ( Ma) ago. They ranged in height from . Their closest modern-day relatives are believed to be the seriemas. ''Titanis walleri'', one of the larger species, is known from Texas and Florida in North America. This makes the phorusrhacids the only known large South American predator to migrate north in the Great American Interchange that followed the formation of the Isthmus of Panama land bridge (the main pulse of the interchange began about 2.6 Ma ago; ''Titanis'' at 5 Ma was an early northward migrant). It was once believed that ''T. walleri'' became extinct in North America around the time of the arrival of humans, but subsequent datings of ''Titanis'' fossils provided no evidence for their ...

Ituzaingó Formation
The Ituzaingó Formation ( es, Formación Ituzaingó), in older literature also described as Entre Ríos or Entrerriana Formation, is an extensive geological formation of Late Miocene (Tortonian, or Huayquerian in the SALMA classification) age in the Paraná Basin of the Corrientes, Santa Fe and Entre Ríos Provinces in Mesopotamia, northeastern Argentina.Ituzaingó Formation at .org The formation comprises s, cross-bedded |
Huayquerian
The Huayquerian ( es, Huayqueriense) age is a period of geologic time (9.0–6.8 Ma) within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification. It follows the Mayoan and precedes the Montehermosan age. Etymology The age is named after the Huayquerías Formation in the western Cuyo Basin of northwestern Argentina that was later dated to the Montehermosan. The most complete Huayquerian fauna is found in the Cerro Azul Formation The Cerro Azul Formation ( es, Formación Cerro Azul), in the Buenos Aires Province also described as Epecuén Formation, is a geological formation of Late Miocene (Tortonian, or Huayquerian in the SALMA classification) age in the Colorado Basin ..., in Buenos Aires Province also referred to as Epecuén Formation.

Psilopterus Lemoinei
''Psilopterus'' (Greek for "bare wing") is an extinct genus of phorusrhacid ("terror bird") from the Middle Oligocene to possibly the Late Pleistocene of Argentina and Uruguay. Compared to other phorusrhacids, members of the genus are both relatively gracile and diminutive, and include the smallest known species of terror bird: with the head raised ''P. bachmanni'' was in height and weighed about , while the largest members of the genus were only about . The birds resemble the modern cariama (''Cariama cristata''), except with a heavier build and considerably smaller wings. The strong morphological similarity between the claws of the predatory cariama and ''Psilopterus'', both of which are sharp, curved, and laterally compressed, may indicate they were used to strike prey. In contrast to the other, larger terror birds, Tonni and Tambussi also suggested ''Psilopterus'' could use their claws to climb trees, and could even fly, but this has been rejected in more recent literature.

Procariama Simplex
''Procariama'' is an extinct monotypic genus of phorusrhacid, which lived from the Late Miocene to the Late Pliocene (11-2 million years ago) of Argentina. Fossils of the animal have been found in six places, in the Cerro Azul and Andalhuala Formations. More specifically in the Andagalá department and in the north of the Belén department of the Catamarca province, with a single location in the La Pampa province. The type and only species, ''Procariama simplex'', is the largest member of the subfamily Psilopterinae. History of Discovery The lectotype of ''Procariama'' (MACN-8225) is a partial skeleton consisting of an incomplete skull, a pelvis, proximal and distal parts of the left femur, distal parts of the right tibiotarsus, proximal and distal parts of the right tarsometatarsus, foot bones and the nail bearing toe bones of the nearly complete left foot, and fragments of the toe bones of the right foot. The genus name was first published in 1914 by Cayetano Rovereto in '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
