Poozeum

The Poozeum, in Williams, AZ, is a museum devoted to coprolites, which are fossilized feces. It sits on West Railroad Avenue, right by Route 66 in the historic downtown. Founder George Frandsen owns the largest known coprolite collection, and the museum holds 8,000 specimens, including Barnum, thought to come from a Tyrannosaurus rex. It is an unusual, kid-friendly stop on this stretch of the road.

What is Poozeum?

Coprolites are ancient animal droppings preserved as fossils. The Poozeum puts about 8,000 of them on display, a collection built by George Frandsen, who holds the biggest collection of its kind in the world. It is a lighthearted subject, but the specimens are real fossils, and the museum treats them as a resource for learning.

The star is Barnum, a 20.5-pound specimen thought to have come from a T. rex. It is the largest coprolite left by a meat-eating animal that has ever been found, and it is the piece most visitors come to see.

History of Poozeum

The Poozeum started in 2014, not as a building but as an online project and resource center set up by Frandsen. For several years pieces from his collection went on the road as a traveling exhibition, showing up in other places rather than in a home of their own. In 2024 the museum finally opened its own physical location in Williams, on the main street of a town that has long lived on tourism.
