Fossil proves existence of giant flightless bird
Fifty million years ago, a 380-pound flightless bird called diatryma stalked the floodplains.
Although diatryma was long thought to have existed in this region, a recent discovery by geologists from Western Washington University of a fossilized footprint of this 7-foot-tall bird proves it did indeed roam the forests of the Pacific Northwest, George Mustoe, a paleontologist at 草榴社区, said. In fact, the track is the world鈥檚 only known track of any giant extinct bird.
