[12] [13] For comparison, the living bird with the largest wingspan is the wandering albatross, averaging 3 m (9 ft 10 in) and spanning up to 3.7 m (12 ft 2 in). When grounded, Argentavis' height has been estimated at 1.5 to 1.8 m (4 ft 11 in to 5 ft 11 in), roughly equivalent to that of an adult human.
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).
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 ...
The researchers said it sheds new light on what the region looked like millions of years ago and the food chain there. Scientists think the region was humid and full of rivers and other water bodies.
The external nares and antorbital fenestras (areas found in the nose) were found to be more square than triangular. These all contribute to a skull that is more rectangular in view rather than triangular. [25] The structure of the fossils also suggest that these birds may have been swifter than originally thought.

The first fossil specimen was mistakenly described as a bird in the family Phorusrhacidae, in part because the bones were so large. In 1961, Pierce Brodkorb reviewed the findings and identified them to have belonged to an owl. Remains have been found in cave deposits from the Late Pleistocene period (126,000 to 11,700 years ago).
Speculative life restoration of Gargantuavis philoinos. The first Gargantuavis fossil was found in 1995 in Var, southeastern France.This first specimen, a fragmentary set of pelvic vertebrae (), was uncovered near the village of Fox-Amphoux in a paleontological excavation and described by French paleontologists Eric Buffetaut and Jean Le Loeuff, who noted the synsacrum's similarity to that of ...
