Bony-toothed bird

This fossil of the pseudo-toothed bird Pelagornis chilensis, of which 70 % are preserved, was found in 5 to 10-million-year-old rock layers in the Chilean Atacama Desert. Including its feathers, this specimen likely reached a wing span of six meters. Thus, Pelagornis chilensis is considered the world’s largest flying bird. The tooth-like projections are the jagged edges of the jawline, which were covered with keratin in live animals.
