Pelagornis

Pelagornis is a genus of huge fossil birds. One species, P. sandersi, is one of the largest bird ever found.[1] Its wingspan was twice that of the largest Albatross. Its wingspan is estimated as about 6.4 to 7.4 metres.[2] The fossil of this particular species is from the Oligocene stage, about 25 million years ago (mya).

The pelagornithids are an extinct group of birds known for bony tooth-like beak projections, large size, and highly modified wing bones. There are many questions about their ecology. The bird was capable of highly efficient gliding. That suggests it had a long-range marine soaring life-style similar to that of living albatross.[3]

Several later species have been found, and they are not quite so large.[4] The whole group died out about three million years ago.
