 And if you're looking to own a dinosaur, who isn't? I mean, come on. You don't have to look any further. We talk about this all the time. The largest and most complete stegosaurus skeleton is expected to be auctioned off in New York next week. Let's take a look at it.

The skeleton stands roughly, what, 11 feet tall and 27 feet long from the tip of its nose to the end of its tail.
