Extinct Bird Species Had Biggest Wingspan Ever
8th July 2014
Researchers have uncovered the fossil of an extinct bird with a mouthful of tooth-like spikes and wings just smaller than a World War I fighter plane’s. At 20 to 24 feet from wingtip to wingtip, the new species had the biggest wingspan of any known bird, outstripping the next-biggest feathered flyer by 15% or more.
