This Dinosaur Poop Themed Museum In Arizona Is One Of The Strangest Places You’ll Ever See
Somewhere along the famous stretch of Route 66 in Williams, Arizona, there is a museum dedicated entirely to fossilized poop, and it is every bit as fascinating as it sounds. Things are about to get weird-and a little gross, in the best way possible.
I recently stumbled upon this place, and yes, it’s exactly what it sounds like. We’re talking about an entire museum dedicated to prehistoric poop.
It sounds like a bad dad joke come to life, but seeing fossilized dinosaur dung is strangely fascinating-and incredibly dramatic when you realize these “deposits” have been waiting millions of years for their big debut. Honestly, it’s the most quirky, unforgettable stop you’ll ever make in Arizona.
Trust me, your vacation photos are about to get way more interesting! If you think a museum about ancient animal droppings sounds like a strange way to spend an afternoon, you are absolutely right, and that is exactly why you need to go.
The Story Behind
George Frandsen did not set out to become the world’s most famous collector of fossilized poop. He started gathering coprolites, which are the scientific name for fossilized feces, simply because he found them fascinating and wildly underappreciated by the scientific community.
What began as an online resource in 2014 slowly grew into something far bigger than he ever imagined.
After years of building one of the most remarkable private collections on the planet, Frandsen made a bold move and quit his job to open a physical museum. The Poozeum officially opened its doors on May 18, 2024, right on the legendary Route 66 in Williams, Arizona.
The decision paid off in a big way, earning the museum a perfect five-star rating from hundreds of visitors.
People consistently describe Frandsen as knowledgeable, humble, and genuinely fun to talk with. His passion for coprolites is contagious, and visitors often leave feeling like they have learned something truly unexpected about prehistoric life.
What Exactly Is A Coprolite
Before your first visit, the word coprolite might sound like something out of a geology textbook. Simply put, a coprolite is fossilized feces, meaning ancient animal droppings that turned to stone over millions of years through a process called permineralization.
Minerals slowly replace the original organic material, preserving the shape and sometimes even the internal contents of the waste.
Coprolites are actually valuable scientific tools. Paleontologists study them to learn what prehistoric creatures ate, how their digestive systems worked, and even details about the ecosystems they lived in.
Finding a coprolite in good condition is considered a real scientific prize, and the Poozeum holds approximately 8,000 of them.
Visitors are often surprised by how varied the specimens look. Some are smooth and rounded, others are jagged or elongated, and a few are enormous.
Each one tells a small but meaningful story about a creature that roamed the Earth long before humans arrived on the scene.
Barnum, The Star Of the Collection
Every great museum has a centerpiece that stops visitors cold, and the Poozeum has Barnum. Named in honor of the legendary paleontologist Othniel Charles Marsh’s rival, Barnum Brown, this extraordinary specimen holds the Guinness World Record for the largest coprolite from a carnivore.
Scientists believe it came from a Tyrannosaurus rex, which makes it about as impressive as fossils get.
Barnum is not just big, it is a genuine scientific artifact that took millions of years to form and decades of dedicated collecting to find and preserve properly.
Seeing it up close gives you a completely new perspective on just how large these ancient predators really were. One visitor even mentioned the thrill of holding the same piece that rock legend Ozzy Osbourne once held during a visit.
The Guinness World Record certification displayed alongside Barnum adds an extra layer of credibility to the experience. It confirms that what you are looking at is not just quirky, it is genuinely record-breaking and historically significant.
The Titanosaur Replica That Will Blow Your Mind
If Barnum is the star, the titanosaur coprolite replica is the scene-stealer you never expected. Standing before a four-foot-wide recreation of what a titanosaur might have produced gives you a very vivid sense of just how massive these plant-eating giants truly were.
Titanosaurs were among the largest land animals to ever walk the Earth, and this replica drives that point home in the most unforgettable way possible.
The replica is built to scale based on scientific estimates, making it both an artistic and educational achievement. Kids especially love standing next to it for photos, and adults are just as likely to pull out their cameras.
It is one of those displays that makes you laugh and then immediately start asking questions, which is exactly the kind of reaction a great museum should inspire.
Few exhibits anywhere in the country manage to combine humor, science, and sheer spectacle quite so effectively. The titanosaur replica alone is worth the stop on your Route 66 road trip.
The Stinker Bronze Statue
Right from the start, the Poozeum signals that it takes its subject seriously while also keeping things fun. Perhaps no single object captures that spirit better than the bronze statue called The Stinker, which depicts a Tyrannosaurus rex seated on a toilet in a pose that is both dignified and completely ridiculous.
It is an instant photo opportunity and a guaranteed conversation starter.
The Stinker was created as a playful nod to the museum’s theme, and it manages to be genuinely clever rather than cheap or tacky. Bronze statues typically celebrate war heroes or historical figures, so seeing one dedicated to a prehistoric predator mid-bathroom-break feels refreshingly unexpected.
Visitors of all ages stop to pose with it, and the resulting photos tend to be some of the funniest souvenirs from any road trip.
Details like The Stinker are what separate a truly memorable attraction from a forgettable one. It shows that the Poozeum has a personality, and that personality is warm, witty, and wonderfully weird in the best possible way.
Free Admission And What That Really Means
Free admission sounds like a small detail until you realize how rare it is for a museum of this quality to ask nothing at the door. The Poozeum operates entirely on donations and gift shop sales, which means every purchase you make there directly supports keeping this one-of-a-kind collection available to the public.
That model says a lot about George Frandsen’s commitment to education and accessibility. The museum is open Wednesday through Sunday from 9 a.m. to 5 p.m. and is closed on Mondays and Tuesdays.
Planning your visit around those hours is easy enough, especially if you are already driving Route 66 and making stops along the way.
Visitors who walk in with low expectations consistently leave raving about the experience. Spending zero dollars to see a Guinness World Record and learn about prehistoric science from a genuinely passionate expert is the kind of deal that makes a road trip feel truly worthwhile.
The Gift Shop Is Genuinely Worth Exploring
Plenty of museum gift shops feel like afterthoughts, stocked with generic magnets and overpriced keychains that have little to do with what you just saw.
The Poozeum’s gift shop is a completely different story. It carries dinosaur-themed T-shirts, educational toys, real fossil specimens for sale, and exclusive Route 66 Centennial merchandise that you simply cannot find anywhere else.
Buying something here is also the most direct way to support the free admission model, so shopping feels genuinely good rather than obligatory. Several families mentioned buying shirts and souvenirs on their first visit and then stopping again on the return trip to pick up more.
When a gift shop pulls people back for a second round of shopping, it is doing something very right. Budget a little extra time and a few extra dollars for this part of the experience.
A Perfect Stop On A Route 66 Road Trip
Williams, Arizona sits right along the iconic Route 66 corridor, making it a natural stopping point for road trippers heading toward the Grand Canyon or cruising across the Southwest. Adding the Poozeum to your itinerary costs nothing extra and takes maybe an hour, but the stories you walk away with tend to outlast every other memory from the drive.
The town of Williams itself has a charming small-town character with historic architecture and a laid-back pace that feels refreshingly removed from the usual tourist rush.
Stopping at 109 W Railroad Ave feels like discovering something the rest of the world has not fully caught onto yet, even though the museum has clearly been winning hearts since it opened.
Road trips are about the unexpected moments as much as the planned destinations. Finding a world-record-holding museum about prehistoric fossils tucked along a legendary American highway is exactly the kind of surprise that makes the open road so appealing.
Put the Poozeum on your map before your next Southwest adventure.
Why Kids And Adults Both Leave Impressed
Museums that appeal equally to a six-year-old and a retired geologist are genuinely rare. The Poozeum somehow manages to pull it off.
Young visitors get the giggles immediately because, let us be honest, anything involving prehistoric poop is going to be funny to a kid.
But the humor never overshadows the real science happening in every display case.
Older visitors and adults with a background in geology or paleontology often describe the collection as outstanding and the owner as someone who can engage at a serious scientific level. One geologist who worked nearby for six weeks called the Poozeum the highlight of their entire stay.
That kind of praise from a trained professional speaks volumes about the depth of the collection. The wordplay throughout the museum has also earned specific praise.
Puns and clever signs keep the mood light and playful without dumbing down the educational content. It is a careful balance that George Frandsen clearly has mastered over years of sharing his passion with the public.
Practical Tips Before You Visit
A few practical details can make your visit even smoother. The Poozeum is located at 109 W Railroad Ave, Williams, AZ 86046, and is open Wednesday through Sunday from 9 a.m. to 5 p.m.
Monday and Tuesday are closed days, so checking the schedule before you arrive will save you a disappointing detour.
Parking in Williams is generally easy, and the museum’s location near other historic Route 66 businesses makes it simple to combine with a broader walking tour of the area.
Plan to spend at least 45 minutes to an hour inside, especially if you want to chat with the owner and really absorb the displays. Most visitors say the time flies faster than expected.
Bringing cash for the donation box and the gift shop is a thoughtful move since it directly supports the museum’s free admission policy. A small contribution goes a long way toward keeping this extraordinary collection open and accessible for every curious traveler who rolls through Williams.
