Pull up an ostrich and make yourself comfortable. I’m going to tell you about a big, flightless bird. A really, really big flightless bird that was much larger than your average ostrich. Now there’s no doubt that nowadays at 220 pounds (or 120 kg.) and up to 2.8 meters, (nine feet tall) ostriches are large birds. But next to Pachystruthio dmanisensis, they look pretty small.
Weighing nearly 1000 pounds (or 450 kg.) Pachystruthio stood 11.5 feet (3.5 meters tall). Which is a lot of drumstick.
This massive bird ruled the plains of what is now Ukraine’s Crimean Peninsula about two million years ago, Science News reports. And so far, it’s the only known bird of this size in the Northern Hemisphere. Pachystruthio did, however, have some huge colleagues in Madagascar, New Zealand, and Australia.
