An Arizona museum tells the stories of ancient animals through their fossilized poop

A new museum in northern Arizona features the fossilized feces of prehistoric animals. The Poozeum opened this spring in Williams along Route 66. President and curator George Frandsen has been collecting the fossils known as coprolites for nearly three decades. His museum features roughly 7,000 specimens, including one suspected to be from a Tyrannosaurus rex. Frandsen holds two Guinness Book of World Records titles for parts of his collection. Paleontologists say it can be challenging to identify coprolite and even more difficult to pin down what prehistoric animal might have left it behind millions of years ago.
