Imagine a basset hound, let’s call him Ollie, older, moves pretty slowly, but still chases birds around his yard. He's probably never caught one, since the little guys fly away fast (probably laughing at him). Luckily, Ollie didn't live 6 million years ago, because back then, some birds didn't play nice.
Meet "the magnificent Argentine bird", also known as the Giant Teratorn, which lived approx 6 million years ago. This was the largest known bird to have ever existed. Check out these stunning figures:
Length - 11ft
Weight - up to 180lbs
Wingspan - up to 26ft(!!!)
