7 (Thankfully) Extinct Giant Versions of Modern Animals

Giants once roamed the earth, meaning many species of animals that are familiar to us have enormous extinct ancestors. Cracked looks at seven of them, some of which have been previously featured individually at Neatorama. Take a look at Argentavis magnificens.

As if answering the dare to make us feel more inadequate, the world gave us Argentavis magnificens, the largest flying bird in recorded history. These beasts possessed a wingspan between 19- and 26-feet, and a wing area of 75-feet, which you may notice is only slightly smaller than a Lear Jet. In addition to its staggering size and 240-pound weight, the bird is believed to have swallowed prey as large as cattle in one fell swoop.
