 Now, a trip to the Poop Museum in Arizona. Here's an interesting place in Arizona to take the kids this summer vacation. This is the Poozeum. It's the world's largest collection of fossilized poop. Everything from the largest coprolite from a tyrannosaur all the way down to a little termite. George Franson created the Poozeum with some 7,000 specimens, one believed to have come from a Tyrannosaurus rex.
