As a response to the podcast, actually, early modern humans (Homo sapiens) did overlap with wooly mammoths (and probably ate their share of them). Mammoths died out relatively recently (10-20,000 years ago). Some are occasionally found frozen in icefields.

there's a whole archaeological tourism business (well, used to be, last time i looked) in going to russia and digging up human dwellings actually made of the bones of mammoths.

It's odd that Dana Stevens picked the one thing in the movie that is actually historically possible (humans mixing with mammoths) and thought of it as an impossibility.

The "Terror Birds" did exist, I've just seen them on Walking With Dinosaurs or one of those specials. They, died out between the age of lizards and the age of mammals.

Saber-tooth tigers (and there were many, it's more of a description than a single species) also mingled with humans briefly, but they would have been smaller and actually had smaller tails than the one in the movie did. They were less massive than modern tigers I believe.

For some reason the "New World" food showing up in the Old World always bugs me. They show CORN -- one of the most emblematic foods of the NEW WORLD -- in the movie. "Take this, it will feed your people!"

And, while most people don't know, the chili peppers the hero munches on are also from Mexico and South America. (They are called "peppers" precisely because Columbus was trying to pass them off as a being close to the prized black pepper spice).
