Argentavis magnificens - the largest bird ever found

Argentavis magnificens (literally "magnificent Argentine bird") is the largest flying bird ever discovered, larger in every aspect than any other flying aves,

This bird, sometimes called the Giant Teratorn, is an extinct species known (as of 2009) from three sites from the late Miocene (6 million years before present) of central and northwestern Argentina, where a good sample of fossils has been obtained.

The humerus (upper arm bone) of Argentavis is somewhat damaged. Even so, it allows a fairly accurate estimate of its length in life, which was a bit shorter than an entire human arm. The species apparently had stout, strong legs and large feet which enabled it to walk with ease. The bill was large, rather slender, and had a hooked tip with a wide gape.

Currently accepted estimates:

* Wingspan: 5.8–8 m (19 – 26 ft)
* Wing area: nearly 7 mē (75 square ft)
* Wing loading: c. 11.5 kg/mē
* Length: 3.5 m (11.5 ft)
* Height: 1.7–2 m (5.6–6.5 ft)
* Weight: 60–110 kg (140–240 lb)
