Llallawavis
''Llallawavis scagliai'' (magnificent bird of Scaglia) is a large, extinct predatory bird from Pliocene Argentina. Its fossil is the most complete fossil of a phorusrhacid (or "terror bird") yet found. Description The fossil, discovered in 2010 in sediment among the cliffs above La Estafeta beach in the lower part of the Playa Los Lobos Allo Formation, contains the complete palate, complete trachea, skull, voice box, and eye bones. The fossil shows ''L. scagliai'' was a medium-sized phorusrhacid around tall and lived in Argentina approximately 3.5 million years ago during the Pliocene The Pliocene ( ; also Pleiocene) is the epoch in the geologic time scale that extends from 5.333 million to 2.58 Habitat ''Llallawavis scagliai'' likely roamed in grassland and weighed ar ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Procariama
''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] |
Phorusrhacid
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 survi ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...
