Argentavis is an extinct genus of teratornithid known from three sites in the Epecuén and Andalhualá Formations in central and northwestern Argentina dating to the Late Miocene (Huayquerian). The type species, A. magnificens , is sometimes called the giant teratorn .
This is by far the best-known species. Over a hundred specimens have been found, mostly from La Brea Tar Pits . It stood about 75 centimetres (30 in) tall with an estimated wingspan of perhaps 3.5 to 3.8 metres (11 to 12 ft), and weighed about 15 kilograms (33 lb); making it about a third bigger than extant condors.
This is by far the best-known and most commonly found species. Up to a hundred specimens have been found, mostly from the La Brea Tar Pits . It stood about 75 cm (29.5 in) tall with estimated wingspan of perhaps 3.5 to 3.8 metres (11.5 to 12.5 ft), and its weight has been estimated within the range of 12.5–15.0 kilograms (27.6–33.1 lb) with ...
Domestication and taming are related but distinct concepts. Taming is the conditioned behavioral modification of a wild-born animal when its natural avoidance of humans is reduced and it accepts the presence of humans, but domestication is the permanent genetic modification of a bred lineage that leads to an inherited predisposition toward humans.
Many of the largest flying birds in the fossil record may have been members of the Ciconiiformes. The heaviest flying bird ever, Argentavis magnificens, is part of a group, the teratorns, that is considered an ally of the New World vultures. [86] The largest ibis is the giant ibis (Thaumatibis gigantea). Adults can grow to 102–106 cm (40–42 ...
Domestication should not be confused with taming. Taming is the conditioned behavioral modification of a wild-born animal when its natural avoidance of humans is reduced and it accepts the presence of humans, but domestication is the permanent genetic modification of a bred lineage that leads to an inherited predisposition toward humans.
The heaviest bird ever capable of flight was Argentavis magnificens, the largest member of the now extinct family Teratornithidae, found in Miocene-aged fossil beds of Argentina, with a wingspan up to 5.5 m (18 ft), a length of up to 1.25 m (4.1 ft), a height on the ground of up to 1.75 m (5.7 ft) and a body weight of at least 71 kg (157 lb).
The only way Argentavis could beat Pelagornis in wingspan is if it had longer primaries, and I mean way longer primaries, each almost as long as the whole skeletal wing. Ksepka (2014) estimate of 5-6m for Argentavis seems more reasonable than the old estimates. Mike.BRZ 07:39, 10 December 2014 (UTC)
