Encyclopedia
Aiolornis incredibilis of the teratorn family, was the largest known North America
n flight-capable bird, with a wingspan of up to 17 feet (about 5 meters) and a huge, deep, powerful bill. A. incredibilis presumably became extinct at the same time as the other megafauna
in North America. It is sometimes called the Giant Condor because of its resemblance to the modern condors of California
and South America
, although it is bigger and in a different family. It is not well known but is quite similar to Teratornis merriami, although about 40% larger overall. Fossils have been found from the Early Pliocene
to the Late Pleistocene
in various locales in the southwestern and western-central part of the USA; it is not certain that all belong to the same species given the large time range and the scrappiness of the remains.

Pliocene
The Pliocene Epoch is the period in the geologic timescale that extends from 5.332 million to 2.588 million years before present. It is the second and youngest epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch...

Late Pleistocene
The Late Pleistocene is a stage of the Pleistocene Epoch. The beginning of the stage is defined by the base of the Eemian interglacial phase before the final glacial episode of the Pleistocene 126,000 ± 5,000 years ago. The end of the stage is defined exactly at 10,000 Carbon-14 years BP...
