I bring you more paleo wtf, hurray!
This time...
That quote is from yours truly.
I know we already had the elephant bird and moa...but those are nothing compared to the awesome that is Brontornis, a Phorusrhacid bird (aka 'terror bird') from Patagonia. He was running around in the early to mid Miocene (about 23-11.5 mya) EATING STUFF UP.
I mean seriously. Yes, moas were big, but did they slice and dice everything they came across?
This thing probably ate early elephants.
Here's a person holding a skull of a related species, Titanis walleri. Related species Phororhacos. But it shows their adorable stubby wings.
And just for comparison...
Sorry.
