10 largest animals on Earth: Argentavis
Natural History Museum Los Angeles
Don't you think it's a little strange that this is the only picture of the fossil that can be found? You would think that if it was real, there would be more recent photographs of it In that museum..? just a thought.
You're right, it is strange, but I'm pretty sure it's real... The Smithsonian magazine has something about it, I'm pretty sure.
