#pseudodontorns

Pelagornis sandersi

extinct seabird that lived ~25 million years ago

Has the largest wingspan of any flying bird yet discovered, estimated ~6.06 - 7.38 m (19.9 - 24.2 ft)

They are one of the false–toothed birds (pseudodontorns/pelagornithids). Their most obvious unique trait is the bony, tooth-like projections on their upper and lower jaws, from which they earn their name. These bony spikes would have served a similar role to teeth and aided these gliding coastal birds in catching slippery prey swimming near the ocean surface (it was unable to land in or take off from water).
