Potato Rock Museum
[Home] [Skeptics]


Welcome to the

It is all about the search for the elusive
“Potato, Rock” or the “Petrified Potato” or the Per Mineralized Potato,

It was 1984, and I was exploring the wild woods of Arkansas.  I would ride my mountain bike in from my home where we were building our home in the woods.  Now I have never been much of a rock collector, and probably could not find a valuable stone if I tried.  But sometimes just being in the wrong place at the wrong time ends up being right. 

I was attempting to cross one of the creeks on my mountain bike, and had popped my front wheel up on the other side when all of a sudden my rear wheel slid out and I went down in the creek.  No harm done to bike or body.  As I was getting up, something caught my eye.  It was up on the bank, and I could not believe my eyes!  What was a Potato doing out here 12 miles from anything.  It was nestled in the pine needles, just like an egg in a nest.  So what to do....  Well much to my and surely your amazement, I walk over and without a second thought, I picked up the Potato.  Boy was I in for a surprise.  That Potato weighed as much as a rock.  Well gosh darn it, that Potato is a rock. 

I stuck it in my hip pack and finished my adventure without any other odd occurrences.  I did keep glancing around, thinking I might find another Rock that looked like a Potato. 

When I got home I took the Rock out to look and to see if maybe my eyes had been playing tricks.  I washed off the dirt and much to my amazement and surely to yours, this thing looked even more like a Potato than ever.  It has a couple of small dents, like “eyes” in a potato, and even has a small groove in one side that looks like a potato that had taken some damage to the skin.  

Later I showed Susie my treasure, and she was very impressed with my find.  Or at least she acted that way.  She sure knows how to stroke my ego.

Since that day I have dedicated myself to finding more rocks that look like food.  Maybe a rock that looks like a strip of bacon, or maybe a rock that looks like a carrot would be neat!  But as the decades have passed, I have come to the conclusion that there just are not that many rocks that look like food.  That’s what makes this rock so special. 

I have had some good times with the Potato Rock.  My favorite is playing practical jokes on unsuspecting house guests.  Aha!  Let’s cook some baked Potatoes.  Imagine the surprise on their faces when they try to cut into their fresh served Baked Potato.  Hey!  This thing is as hard as a rock!  Mu aaah haaa haaa haaaaaaa!

One Potato, Two Potato, Three Potato, RockHere is a group picture of my Potato Rock hanging out with a couple of real spuds.  Which one do you think is the Potato Rock. 
Is it the potato on the left?  Nope!  
Is it the potato on the right?  Nope!
If you guessed the one in the middle, you are correct, and you made a lucky guess.  Extraordinary isn’t it?

Below is a larger photo of my Potato Rock in all it’s glory!.  Magnificent, isn’t it.  Many have offered me money for my unique rock, but I have declined.  Sure I could take their measly hundred dollars, and then what would I have.  I would spend the money foolishly and I would no longer have my beloved rock. 

Potato Rock is larger than actual image.  So I have built a Web Page for my Potato Rock with hopes that others can marvel in this mystery of creation.  Is it a fossilized potato?  Is it a petrified potato?  Well whatever it is, it is very cool, and it is mine.  I also hope to find others that have found rocks that look like Potatoes. So if your out there, and you have a rock that looks like an Potato, contact me and I will be glad to add your find to the POTATO ROCK MUSEUM

Check out all the great Potato Rocks that have been added below to the Potato Rock Museum since my opening of the Potato Rock Museum.

A Real Per mineralized Potato? (Petrified Potato)

I have had about 5 people share their potato rocks that they have found.  This one is worth posting.  The owner of this rock had it tested by the Museum of Natural History, and with microscopic examination, they declared that it showed like structure to a real potato.  No carbon dating was done.  The owner states the Museum offered to buy the rock for $1,500.00 dollars.  The owner declined the offer but would be willing to part for a “Very Significant” larger dollar amount.  Were talking big buck here!

The Story about the above Potato Rock.

By R.  S.

"The Spud" It was given to me in 1980 and I had it examined at the Museum of Natural History in "82. The three persons there offered me $1,500.00 for the thing and I turned it down knowing that if was worth a thousand... it was likely to be worth ten thousand. I've recently search for auction links through high end organizations to try and get the very most out of it. Well, I approached the Millionaires Club to ask if they wouldn’t mind posting it mind one of their links to sell and got some interesting replies. No offers though. A self-made Millionaire in Canada has been fascinated with it and assisted me with the suggestion to post it with the Billionaires Club on possible links that sell Estates, Manors, Islands, etc. stating that "Millionaires don't like to lose their Millions" and that "Billionaires make a Million in less than a week". Pretty sensible thinking. Also said a Million wasn't high enough for eccentric wealth...and 5 million was a scary figure, so, 3.5 was set for the asking price on the Spud. I've receive two interesting replies. One, at last contact, asking if my price was firm? It's been less than two weeks since our last e-mail and no new news on the matter of reply.

And Another Potato Rock!


By Benjamin C. Wright

Several years ago in the nineties, I and a friend were touring an old Virginia Plantation. We took a break from the walking and sat on one of the benches along the path. After a minutes rest, I decided to take a walk in the field behind us, and look for some unique stones or rocks to take back as souvenirs. I usually do this when away on a vacation.

As I walked and looked, I spotted a potato lying on the ground. I thought that odd, and went to pick it up. To my surprise it was heavy and hard more like a rock. On quick examination it had all the characteristics of a potato. I walked back to our bench, held it up and asked my friend, “What is this?” He said, “A potato, of course”

When I let him hold it, he said, “It’s a rock or a rock potato.” We sat and gave it a serious examination and agreed that it was in fact, a petrified potato.

I have since over the years shown it to hundreds of people, with the “before and after” approach, and every one of them has concluded that it is a potato rock. (That is, except for a couple “experts”.) Seeking validation, I took my potato rock to a local science museum. They concluded that it was just a quartz rock called Chalcedony, and not a fossilized potato. I could not agree, for “seeing is believing”. I looked up Chalcedony and found that this mineral frequently pseudomorphs (1) after organic materials. A well known example is petrified wood, wood that has completely transformed into Chalcedony {or one of several other minerals}(2). I took my “rock” to some “experts” at the State Department of Natural Resources. Two of them immediately said it was just a rock, but one said it should be x-rayed to tell for sure.

This remains for me to get done. My research reveals that petrification can occur when the cellular cavities of an organic object become saturated with a liquidized mineral,(usually Quartz or Silica), and become hardened over time and conditions of burial and climate changes.

On close examination you can see externally, that my rock is as a potato due to:

1.Color, shape & size; 2. Various skin textures and color tones; 3. Potato “eyes”; 3. Fiber-like material in apertures; White “meat” areas where skin removed.

1. Pseudomorph: A mineral possessing the external form characteristic of another.

Another Potato Rock Story
Posted: December, 16, 2007


I've found a lot of strange things over the years, and this Petrified Potato has to rank in the Top Ten strangest finds.

Considering how many states I have traveled through and/or lived in, I hope you will forgive me if I can't be entirely sure where I found this odd bit of History. All I know is that it had to be somewhere between Phoenix, Arizona and Crescent City, California. I have kept this Potato safe and happy for over 15 years.

The Potato is 5 3/4" long and about 3" wide. A good sized baker. It weighs only 4 ounces.

It looks just like a standard garden-variety potato. Same color. Same indentations you would expect. But it's so light! And it's certainly no longer edible.

After reading the potato stories on this web site, my husband and I have decided to have someone take a look at it. I'll let you know what we find out.

Another Potato Rock found in a Garden
Posted September, 2008

Potato RockHello I found this rock while watching my husband roto-till our garden. I thought it was a real potato he had tilled up. What a surprise when I picked it up and it was cold and rock hard. When i show it to people they always ask me if it could be a petrified potato. I tell them anything is possible. The first image shows an "eye" the second shows a long blemish. one end is even a little wrinkled looking as if it was beginning to spoil.

Like you I love my potato rock too!!!

Wow!  This Tater Had a Few Bruises, But Still a Nice Potato Rock!
Posted May , 2010

Potato RockI found this @ 20 years ago while off-roading on the mountains surrounding Lake Havasu, AZ.  We stopped in a clearing that looked like a perfect camp site for somebody but it still seemed we discovered it ourselves (we were in a very remote spot and made our own path to get there). I was at the edge of the area and looked down and saw the old rotten potato and felt bummed that others had been there before.  I kicked it aside an felt the weight, very heavy for it's size, picked it up and was immediately fascinated. "Hey, I found a petrified potato!", I called to my friend, he agreed.  It was unlike any of the other dark, small, jagged rocks it the area, it stuck out like a sore thumb.  It haves many eyes, some tiny hair line fissures and a few rotten spots, (I am very familiar with them as I had to clean and dig out the rotten spots from thousands of bulk potatoes when I worked in a restaurant in high school).  It also haves some old, rock-hard dirt on the skin indicating it was buried at one time.  I use the word skin because over the years it had gotten scratched revealing a totally different color and texture just under the paper thin covering.  It is also irregularly shaped like a potato, not round like a river rock, yet it's smooth and haves a natural slight sheen to it.

 My own theory is that it was found somewhere else by someone, (possibly a native American dug it up while farming), then brought it to their camp, at that site, and cast aside being an inedible rock, then I stumbled upon it, literally, many years later.

 I have shown it to many of my friends and family, all smart educated people, albeit no one in the business of ancient side dishes, many skeptics among them, and the evidence only points to the same conclusion by all... that it IS a petrified potato!

 That's my story and I'm sticking to it!

Deer Hunt yields a very nice Potato Rock!
Posted April 4, 2011. 

Potato RockMy nephew and his friends have a hunting club with several deer stands. My grandson Calvin Chilton had shot a deer just before sunset and when all the hunters exited their stands, My Nephew Billy Knight, His Daughter, and his friend Jason Murray went looking for the deer in the woods, while I was looking for the deer, I stepped on what I thought was a potato until I picked it up and it was a rock that looked just like a potato. I got permission to keep it and I brought it home with me in Reidsville, N. C. I have a set of balance scales and I weighed the Potato rock and it weighs two pounds plus or minus and ounce. My friend Mr Ed English and I go to the same church and he I consider is an expert with rocks. He said it looked like Quartz, He advised me to hold onto it. I have had a lot of fun with it, everyone I show it to thinks it's a Potato.  “A potato until I say hold it and they say it's a Potato Rock!”

New Brunswick Potato RockPosted August, 27, 2011

My daughter was playing in a field and found what she thought was a rock and gave it took me and I had a look at it I knew it was a potato. A “Petrified Potato”!  so I sent it to the Saint John museum  of Newbrunswick, Canada and  they said it was quartz and they wanted to cut it open!  I said no...  I was suppose to bring it to a rock specialist but I never did but I got offered 5000 for it but it wasn’t enough  I never heard about another one  found in Canada yet.

I have now had it in my possession for over 17 years now, and it is for sale for the right price!

Potato Rock with Curious Drawn Markings-  Very Interesting!
Posted September 20, 2011

Rockland New York Potato RockWe live in Rockland County, NY an area known for it's alluvial deposits. We were however pleasantly surprised to find this wonderful "potato rock" in our yard while doing some landscaping. 

On close inspection we found on what had been the underneath side of the rock, the appearance of some kind of drawn on markings..faint but too regular to have been natural.

When held in certain light you can see round shading where the "hands" might be on the upper left and right "arms"...very interesting. This is on the  bottom down point as we found it.

Please feel free to share it. I just think they are an incredible link to a very distant past. 

What a unique object to have.

Maryland Potato Rock
Posted September 25, 2011

Maryland Potato RockOur Potato Rock has been in our family since 2006, however, it has been buried in our yard for a very long time, I suspect. 

We moved into our little farmhouse in October of 1991 in Baltimore, Maryland and in 2006 we broke ground in order to build an addition.  We went from a 2 bedroom to a 4 bedroom house.  We also added a basement. Our excavator was digging this basement in October of 2006 when he spotted this potato rock from atop his machine.  He stopped the machine, got down and picked it up, thinking it was a potato.  We were shocked to find out it was actually a rock.

Since then, my boys and I (as well as my students, as I've taken it to school a couple of times) have wondered: Could it be a petrified potato?  Is it a dinosaur egg?  Could it be a geode?  What's in it...and what is it?  Yesterday, my 15 year old picked it off my desk and said, "Why do you still have this"?  I said, "You know what, let me Google it".  And the rest is history...We found your website!  How cool!  What is it, anyway, and what is in it?

Thanks for doing this!  We don't feel so alone anymore!

Portugal Potato Rock
Posted February 23, 2012

Portugal Potato RockMe and my boyfriend found 'potato weight' on a beach in Portugal. It immediately struck as us looking very potato like but we presumed it was a rock and thought nothing more. We packed it in our suitcase as we thought it would make a lovely paper weight hence the name.
 3 years passed and one evening for some random reason it came into my thoughts. I found it and was convinced it was actually a fossilized potato. Why it took me 3 years to realize this I do not know. We then found this website which has made me very happy, particularly the parts about money! But in all honesty I don't know if I could part with potato weight we have grown close.

Colorado Potato Rock together with Maryland Potato Rock
Posted April 17th, 2012

Colorado Maryland Potato RockThe Potato Rock portion of this story started at some point in the mid 70's, we're not really sure specifically when, but that's how the 70's were. One rock was discovered in Colorado, the other in Maryland, both were picked up as really unique rocks, something that each person had never before seen, both were discovered while on camping/hiking excursions.

The two people in this story are Jack and Jody. They have known each other for 50 some years, since 1st grade. They went through elementary, some jr. high and all senior high at the same schools. They had similar circles of friends, but mostly the circles overlapped and although these two young people knew each other, the friendship between them did not exist yet.

They did what many people do; had girl and boy friends, got married several times, had responsible jobs and enjoyable hobbies, had no children. Over the course of the next 30 years their paths crossed several times but mostly just came very, very close to crossing. Then came Facebook!  Jack was poking around one day looking for high school acquaintances and came across Jody and asked her to be his friend . She accepted and during the course of their becoming reacquainted, Jack mentioned that he had a great rock that he found out in Colorado and he had carried it back with him across the country. Jody mentioned that she also had some rocks that she carried around with her from place to place and how that Jack was the only other person she had ever known that carried rocks with them from place to place throughout their lifetime. Fast forward 2 years. Jack and Jody are in a relationship with each other. One day they are talking about the rocks again and the fact that they are both shaped like baked potatoes came to light. Very, very curious, they both thought.  They each took photos and e-mailed them to each other. Jack phoned Jody after receiving her photo and said, "I think you better go look at your e-mail RIGHT NOW!  Jack brought his rock to Jody's house and that's how they (the rocks) came to be side by side in the photo. Jody found the web site for the Potato Rock Museum and well, this is our story and we're sticking to it. Here are 2 rocks, possibly 3000 years old, providing yet another sign to these 59 year old youngsters.

Candor, New York Potato Rock- In search of Treasure!.
Posted July 3rd, 2012

Potato Rock DiscoveredI found this potato rock on July 1, 2012 in Candor, NY. We were in the forest using a metal detector to look for metal objects near some rocks that we believe to be the remnants of the foundation of an old home. After getting a signal in one spot we dug down a foot or two and found some very old metal nails and spikes and a piece of an old iron stove. Much to my surprise, we also found this amazing potato rock! It was buried in the dirt but it was so round and smooth that I knew it was not a regular rock. It looks exactly like a potato (with eyes and everything), but it is definitely a rock! You really cannot tell that it isn't a potato until you pick it up.

Just this afternoon I went to grocery store to purchase a few things for dinner including a bag of potatoes. To our surprise as the bag was opened and while removing the potatoes to be washed and prepared this heavy "potato" caught our attention. I have never seen anything like it. So of course after much discussion and photos I could not resist Googling this rock. I found your site. Amazing!!!

I have never seen anything like this in my 40 plus years. Thought you might enjoy this. I will definitely keep this as I am sure it will be an excellent conversation piece in the years to come. Happy Thanksgiving.

Another Potato Rock found in sack of Potatoes
in Rancho Mirage, California!
Posted February 19th, 2013

Rancho Mirage California Potato RockSo, my potato is certainly not as rare as I thought ! I was a produce clerk for ten years, so I know my potatoes. When I was assistant store manager at the Vons (Safeway Co. store) in Rancho Mirage, California, a lady brought this in to me with a complaint. She had bought a 10 lb. bag of potatoes and this was in it. I was flabbergasted. I gave her a refund for the bag of potatoes and kept this one as a souvenir, as she didn't want it. It has all the markings, and no cuts in it.

Thank you for posting your web page on this.

Potato Rock found hidden in the Marigolds
in New Jersey!
Posted May 1st, 2013

New Jersy Potato RockI live in a community town house in New Jersey. I had a bush and two trees removed from my front patio back in 2010. But It was not until Sunday April 28th 2013’ when I made the discovery while planting African marigolds. My first reaction was that I had found the Shankar stone from the movie India Jones and The Temple of Doom.

I made a joke about it, when I called my wife to the front door. Ironically this was her favorite Movie.

So while holding the stone I began Chanting Ohno shba, Ohno shba Ohno shba!!! The stone will be found but you will not Dr. Jones. Needless to say my wife lost it with laughter.

The stone sat in my home a few days. That is when I decided to conduct an internet research.





Potato Rock Lost in Massachusetts
Posted August 22nd, 2013

I have a sad story to relate. I tell it to you because, well, frankly... I don't think anyone else would understand.

When I was a child, the youngest of ten in a big Irish Catholic family, we came into the possession of a potato rock. 

It came to us in a 10lb. bag of potatoes, and looked so remarkably like a potato that we thought it must actually be a petrified potato, mineralized by some strange process, like a spaceship landing in close proximity to a potato patch. Potatoes grow in Idaho, where there's plenty of space for UFO's to land. 

Or maybe it was an ancient potato buried with an Native American (which we as politically incorrect inhabitants of the seventies referred to as "Indians.") used in some burial rite to signify abundance in the afterlife.

Or maybe it was just a rock that looked like a potato.

At any rate, it became a family jewel. We brought it to show and tell, we would drag it out at parties and pass it around. It had one divot on its surface that fit perfectly the tip of a pencil and looked like a potato eye. For decades we treasured it and fought over which of us kids would inherit it. We were poor, and the potato rock really did seem like the most valuable item in the family. It was destined to be an heirloom.

Then. One day. After vamoosing the last kid (me) our parents decided to up and sell the old house. They packed nearly 40 years worth of stuff up, and in the process, the potato rock disappeared. There has been quiet distrust among us Kelley kids since. Though each insists that he doesn't have it, I know we all secretly suspect that it lay hidden in some safe deposit box, the key to which lay in the possession of one of our sibs.    

I do not have it, I assure you. 

For the sake of family cohesiveness I do not press the issue. But I miss that potato rock. And I'm so disappointed that it will never be featured in the Potato Rock Museum!

Upstate New York Potato Rock
Posted March 27nd, 2014

Upstate New York PotatoRockI have had this potato rock for probably over a decade. It was found in upstate New York, but the guy who found it was about to toss it! One side has a some marks, but nothing un-potato-like.

I keep this in a zip-lock plastic bag in my refrigerator (with a few drops of water so it looks like there’s condensation). Because if it were a potato where else would it be? And so that once in a while I come upon it again and I am delighted all over again. But one day some 'helpful' visitor will clean out my refrigerator and seeing this obviously not good potato will throw it away for me, so I am glad that I'll at least be able to find it on line!

I'm glad this rock can enjoy it's 15 minutes of fame at some point during its eternity!

It is so great that you provide this place for us potato heads to share!

Northern California Potato Rock
Posted April 9, 2014

Northern California Potato RockI have worked at my job for over 14 years and in the back of one of the buildings that I walk by every day there is this rock. Over the years I have looked for it when I passed by and would say "Hi Potato Rock glad you are still with us." The rock is just a landscape rock which was probably trucked in from some place in Northern California but today...I picked it up! I admired all the little indentations or eyes and just like someone was preparing it to make mashed potatoes, found a large dark spot on the back and cut it out with a knife thus the big hole in the bottom and of course all the sparklely crystals inside. I went online to see what type of rock it was and was bounced all over from one website to another and decided to simply type in "potato rock" cause that is what it is. And then to my pleasant surprise I was not the only one who was excited about their find. Mike thinks it might even be a geode, how cool would that be to bust it open? I think I will leave it just as I found it. But placed strategically on my desk alongside my stapler and tape dispenser---tomorrow I plan to bring in a big fat carrot and sit it next to it and see what people say. Wouldn't that be sad if they didn't even notice? Slow down, smell the roses and enjoy the potato rock, I say!! Thank you for letting me share my silly story about the potato rock.

Sliced and Fried Tater Rock Anyone?
Posted April 27, 2014

We acquired my father in laws rock collection which he collected about 50 years ago. Most of his collection was found in north eastern Oregon. He found lots of agates, jasper, petrified wood, mammoth teeth and other rock that I can't identify.

I enjoy jewelry making, and acquired a little rock saw with grinding wheels, and have been making cabochons and wire wrapping them for pendants. I saw this rock and wondered what it looked like in side, if it would make a good cab.

I was surprised when it was white inside so I cut two more slices. Then it i noticed ,oh my goodness!, it looked like a potato inside and out. Oh no! did i cut up a fossil!

The inside looks like potato flesh, and the outside has places where eyes could have been. I went to the Internet and discovered your site, and other sites telling me it couldn't be a potato fossil, but it sure looks like a potato and every one I show it to says that's definitely a potato. I don't believe it could have been formed by a glacier. The white wouldn't look just like potato flesh.

Potato Rock uncovered by dog in Kewanee, Illinois
Posted Posted September 5th, 2014

KewaneePotatoRockWhen I was 10 (1981) I was playing in my back yard and found this petrified potato. There is not really a cool story on how I found it. At the time I lived on Main Street in Kewanee, Illinois, so I wasn’t really out exploring. I just found it sticking out of the mud where my dog had worn the grass down from running back and forth at the end of his chain.

It is hard like a rock but very light and I am assuming this is because it was broken in half before the petrification which caused the inside petrification to be more porous. That’s just my educated guess from my year of Physical Geology at community college. So I am no expert by any means.
