From One Specimen to Thousands
In 2014, George Frandsen launched a website dedicated to coprolites—fossilized feces—after starting his collection at age 18. His collection grew from a single specimen to over 8,000 by 2024, earning him a Guinness World Record and leading to the museum’s creation.
Barnum, the Record-Breaker
Among the collection is “Barnum,” a 9.28 kg, 67.5 cm long coprolite believed to be from a Tyrannosaurus rex. Found in South Dakota’s Hell Creek Formation, it contains crushed bone and high calcium and phosphorus content, confirmed by X-ray analysis.
From Online to Route 66
After years of traveling exhibits, Frandsen opened the physical Poozeum in Williams, Arizona, on May 18, 2024. He left his corporate job, sold his home, and moved west to display the world’s largest coprolite collection to the public—free of charge.
Dung That Draws Crowds
Visitors can see a 4-foot Titanosaur poop replica, the bronze “Stinker” statue of a T. rex on a toilet, and coprolites spanning 400 million years. The Poozeum operates with the slogan “#1 for fossilized #2,” offering both science and novelty in one place.
In 2024, George Frandsen opened the Poozeum in Williams, Arizona—home to the world's largest collection of coprolites.
