Paleontologist Dan Ksepka examines the fossilized skull of what may be the biggest flying bird ever found. Its telltale beak allowed Ksepka to identify the find as a previously unknown species of pelagornithid, an extinct group of giant seabirds known for bony tooth-like spikes that lined their upper and lower jaws.
