I've seen pictures of this animal at a museum of natural history. I think it was the Carnegie in Pittsburgh.

They really do have the remains of this beast at museums around the world. I'm sure the photo is a scientist's rendition of what the animal may have looked like.

Obviously, there were no cameras 10,000 years ago, and according to one source, there wasn't even a planet earth.

So yes, it's a fake, but yes, that animal did exist as advertised.
