- KINGSLEY NORTH -
Kingsley North is a lapidary store in Michigan's U.P. They make a great cab machine and sell many other brands too. They have a huge selection rough rock, tumblers, grit, jewelry supplies etc. at good prices. I buy most of my coarse grit from here in 45 lb. bags. It's the best price I have found. If you buy using the following link, I make a small commission.

You mentioned previously that most people tend not to watch the slide show at the end, personally I think they are great as it does a great job showing the beauty of the rocks. I suspect that is the most time consuming portion of making these videos so I wanted you to know that some of us really appreciate them and all your efforts.
Thanks, I appreciate you showing your appreciation. The slide show is by far the most time consuming to do, but since it shows the rocks better than video, I think it's worth doing. I'm glad you enjoy that part.
Wow! I'll be looking for some fossils to polish now.
I really love the fossils of Michigan and these are beautiful!!!
I thought they were pretty nice. We have quite a variety here.
Oldie but a goody! Always fun to come back and see them again.
Cool rocks. Man. I enjoy. And relax just watching your rocks and narration. As being a Rock hound myself! Thanks!
Great, I'm glad you're enjoying them.
Tuesday November 3rd, there was something really important I had to do today....oh, what was it? Now I remember...Rocks In A Box.
I'm glad you have your priorities straight.
Lovely variety of unfamiliar stones. Loved it. Great polishing too.
I'm glad you liked it. We have a lot of this sort of stuff in my area. It's always fun to see what other people can find, isn't it?
@@MichiganRocks It sure is! I really enjoy your videos and look forward to more! Happy Holidays and good luck with future hunts!
I just love the fossils. So cool, and so many interesting little parts to look at. Great Box 👍
Yep, they are pretty cool.
@@MichiganRocks I've never seen anything like them, I hope we have something like that here in New Zealand. 👍
I'm so happy you did a fossil box I have so many that I am afraid to throw in the tumbler!! This gives me hope! 👍👍😊
These are pretty tricky to tumble. Be careful.
Love these, so interesting and beautiful. And the cracks, all I can say is that I'd be showing cracks too if I were millions of years old!
I guess I can give the the cracked ones a break when you put it that way.
@@MichiganRocks thanks...my male friend ignores my wrinkles, so we (the eocks and I) are good! Keep up the awesome videos!
I love your slideshows
I watch it at .25X speed so I can examine the rocks just like I would if I were picking on a beach.
Wow, that’s slow!
Beautiful details, lots of visibility. Thanks for sharing
You're welcome, I'm glad you liked it.
I so appreciate all your videos. I watch first thing in the morning with coffee and have learned so much.
I'm glad you're enjoying them. I've been enjoying these Rocks in a Box videos because they've forced me to take some time to look through all these rocks that I've tumbled in the past. It's been fun seeing them all again.
For years I’ve collected rocks like these. Now know the names. And I really like how pretty the are polished. Thank you for sharing.
I'm glad I could help. Are you going to tumble them?
@@MichiganRocks if I had a tumbler, yes I’d tumble them. I had hand sanded a Petoskey stone one time. That was fun.
Thanks so much love seeing these especially living in Michigan
We do have some pretty cool fossils in Michigan.
I LOVEL LOVE,LOVE OF ALL OF THEM..THE FOSSILS JUST BEAUTIFUL WOW!
Thanks for all the vids, I was able to hit the public areas in petosky for a day and have an assortment for the tumbler
Are you aware that limestone fossils like these are very difficult to tumble? I have made a few videos showing some ways to polish them with or without a tumbler:

Lovely indeed, pretty amazed to watch such a beautiful fossils when polished.
Fun to see how they polish up and how different the fossil form. The Dissection is so fascinating. Similar but different from agates.
I look forward to your channel every week.
That works out well because I put out a couple of videos each week. It would be a shame if no one was looking forward to them.
Love the flat black one so much. but really, they are just wonderful. you are lucky to have them.
I like that cladopora quite a bit too. It also polishes a bit better than the other fossils
You always find the prettiest stuff. They polished up well.
I was happy with the polish on most of these.
Can't believe I missed this video. All of them are amazing! Michigan is on the bucket list for this summer. I'm excited to go there even if we don't find much. It's a beautiful state! Fun just rock hunting. Awesome rocks in box.🌟
I can’t believe it either! What were you thinking?!?
I haven't commented in awhile, but dude. These are awesome. I get the self criticism but you are doing an amazing job. I am in New England and our geology is so different. I love it. Keep up the outstanding content my dude!!
Will do, Drunk Josh. Expect another Rocks in a Box video next Tuesday.
Great close ups in the slide show. Can clearly see the crystal that formed in the cavities of the deceased animals' skeletons especially on that one particular horn coral. Stunning!
It's amazing how much detail some fossils have considering that they're about 350 million years old.
Awesome episode. I learned that the Petoskey stone I hand polished using your automotive sand paper method is actually Cladophora with Petoskey in it! How exciting. I wish there was a way I could send you a few pics of it.
That's not super unusual to have several different fossils together in one rock. I like those. You can always post a picture somewhere else and then post a link here. I've used imgur a few times for that. I don't think you even need to have an account.
Alll beautiful!! You have polished them perfectly...not always happy with cracks either but split them or accept the crack..🥴😁
Yep, those are the two options with cracks. I do both, depending on the rock.
How did I miss this video? I love fossils. These really are so cool. I really like the black/grey/white tones & the variety of patterns. As a painter I like to create abstract drawings with India ink & paint so I find these so inspiring.
I'm glad your inspired, but really disappointed that you missed any of my videos. The nerve!
Do you plan to draw some of these fossils? If so, I'd love to see the finished drawing.
@@MichiganRocks I’m in the process of a big project but yes, I think I will use these as inspiration for a series of pen & ink sketches. I’ll probably use balsa wood and bamboo chop sticks and combs and other things to make the marks. I don’t do realistic work. Not everybody likes abstract art. But when I do this I will definitely show you.
@@micheleboyd1830 Thanks. I'll have to admit, that I tend to like more realistic art, but some abstract art can be cool too.
Very very cool corals! Lovely polishing work...
Thanks!
I have a ton of all of these from my trip to Lake Huron this past weekend. How did you tumble these? All I have is a rotary. I do hand polish my Petoskeys. Sorry I ask so many questions, but you are basically my rock guru. Everything I know about polishing I learned from you!
I'd suggest tumbling them for the first two stages (through 220) in your tumbler and then polishing by hand after that. I don't remember what I did with these, but I suspect that I finished them in dry corn cob media in my Lot-O tumbler. Treat them exactly as you would a Petoskey stone.
I like these gorgeous shiny coral rocks with all those tiny details 🥰
They're pretty amazing.
Love these !!! So much!! I’ve polished a few and hope to do more. Thanks I’m crazy for fossils and rocks!
Good luck with your polishing.
These are so cool. So many different kinds!
Beautiful and fascinating. Thanks for sharing. I always learn something new.
You're welcome!
Perfect Stones my dear Friends anbeautiful vídeo.
Thanks again, Alé!
God creates such delicate wonders for us.
He sure does. It's just amazing how many cool things he made for us to discover.
Can you tumble fossils with other rocks? I am having trouble deciding which rocks that I've picked up on the beach I can put it together. I'm doing some agatized petrified wood next so I won't get to do it for a bit, but I intend to do a load of rocks that I personally picked up after the agatized petrified wood. Do you have a link that could help me identify some of these Michigan beach rocks, I know that people say we ought not to put different hardnesses in together and I just want to get your insight on that question. Sorry I always have 3 questions in one. That last time I asked you were a great help and I really appreciate it. I don't know if you've ever tumbled any agatized petrified wood, but that stuff looks like it will be beautiful. Looks like glass rock wood chunks when it's raw so I'm sure it'll take a nice shine.
Tumbling limestone fossils takes special methods. I do them in a vibratory tumbler with dry corn cob media. You do not want to mix very soft rocks with hard rocks. For harder beach rocks, I routinely mix slightly different harnesses in my Lot-O vibratory tumbler with good results. I think vibratory tumblers are more forgiving. I don't have nearly as much experience with tumbling in rotary tumblers from start to finish. Here's my Petoskey Stone (limestone) method: ruclips.net/video/grSlZ835VDo/видео.html
I have a few books on Michigan rocks listed in my Amazon storefront. I've run across a few websites with some info, but I don't know what they are off the top of my head. A little searching should help you find a site or two. Here's a video I did identifying some Lake Superior Rocks that might help: ruclips.net/video/A8a-9Y4Tp24/видео.html
A very interesting and beautiful selection.....thank you! 😉☺️😉
You're welcome, I'm glad you liked them.
wow. Those are lovely! I’d watch your channel over elections any time! 😎
My wife has the election results on right now. It's sort of silly since they just keep saying it's too early to tell. I'd rather just wait until tomorrow.
Amazing amazing! I have a small bucket of fossils like that but I'm so afraid of tumbling them because they are soft.. Can you let us know how many days it takes for stage 1 & 2? Thank you
Some day, I'll do a complete video on how to tumble these. They're not easy to tumble. Stage one and two are not the problem, it's after that that things get tricky. I tumble for 3-4 days at a time in 80 grit silicon carbide. I check them after 3-4 days, remove any that are done and put the rest back for another 3-4 days. When I have enough for the second stage, I use 220 grit and run them for one day. I overfill the barrel to give them a more gentle ride. I'd say I fill to about 80%. Sometimes I use plastic pellets for the second stage, but then I run them for two days, because the the plastic slows grinding down. Here's a video of me doing this with Petoskey Stones: ruclips.net/video/IBRq7dPD0Lk/видео.html
That last picture of the slideshow, so cool!
I'm seeing texture in the sheen of most of the fossils. It makes them look extra cool. Can you feel the texture? Thanks for tonight's fossils in a box!
There is texture. It's not super obvious to the touch.
Never dreamed that I would be watching a guy showing me ROCKS ! Love it !
I think you're the second person who made almost the same comment on this video. I'm not sure why this is being shown to people who are not into rocks. These are not my most popular videos, but the people who like them seem to really like them. I also do videos of my rock hunts that are more popular.
OMGoodness! I think this comment is SO funny!😆😆😆
Nice rocks! I see I need to visit the Charlevoix area! Needed a break from the news....thx!
Charlevoix stones are found in other places too. These are all from Lake Huron.
I love the sheen on them. Did you tumbler and if so how long at what grits?
Please and thank you
I did tumble them. I will probably do a video on the method at some point.
@@MichiganRocks I would love to see that video. As always great job Rob!!
Yes would love to see that video. I am obsessed with my double barrel lotto and have found a ton of cool coral pieces on the Illinois side of Lake Michigan. I’d love to shine them up a bit, but am worried ruining them all. I currently use your lot-o formula for all my tumbling.
@@betsyallen4821 How's my general purpose Lot-O recipe working for you?
Your formula is working out great so far. All mistakes are user error on my side. I’m slowly figuring out which rocks to keep and which ones won’t shine. I just want to say thanks, your content has been a beacon of sanity in these turbulent times we are living in. Your videos walking the shore and picking up rocks reminded me how much I have always loved to do that, and inspired me to hit up my local beaches and search for rocks. Keep on keeping on and sharing your lessons with us.
Great example of tumbled fossils!
Thanks!
Hi Rob I love this video and all of your videos. Just curious when tumbling these fossils what’s your system is as to how long in the rough tumble etc. Thanks for any information you can share, have a great night!
I treat these like Petoskey stones. I have a few different videos on how I tumble those, but the best of those videos is probably this one: ruclips.net/video/grSlZ835VDo/видео.html
I'd probably walk by some of these on the beach but polished, they look so nice. I'm assuming you collected these along the shoreline near Alpena. Maybe Rockport? We're heading up there tomorrow for a 4-day weekend to take advantage of our Indian summer. Haven't been to Alpena in over 20 years so am really looking forward to walking along the shores and seeing the sites. Can't wait! My goal is to find a pudding stone!
I'm sure some of these came from Rockport and most of them were from the general area.
Those polished coral fossils are beautiful! Once in a while we will find a coral fossil but they aren't that great, pretty beat up. Thanks for showing us these Rob!✌️🤠
They aren’t all keepers, that’s for sure. It’s fun when you find a really nice specimen.
Hey Rob
I have some fossil rocks like that but wasn't sure about polishing them but I know what to do now. Thanks , yours look great as always. Its funny how I can find the same rocks in my backyard as you do in your backyard and be so many miles apart. I've found that rocks in the rivers by me are relatively the same. I hope to find different ones next spring when I go on a rock trip to the south end of alberta.
Just be careful that you don't ruin them. I have a pretty specialized method I use for these. They're mostly limestone, so you can tumble them away to nothing very easily.
Hey Rob
Thanks for the advice. I guess I have a lot more learning to go and not asume. The rocks I have aren't like sandstone, they are more like your ones that have a black back ground ,but in saying that I will learn more before I jump in and polish.
I'm a Michigander as well. I found about two dozen of these types of fossil rocks in my uncles rock flower beds, even three nice Petoskey stones. I'm new to tumbling, did you do the normal 4 grit routine? I'm nervous to tumble, as I wasn't sure if it would just grind the fossil right off
Fossils are not a good rock to start with. They're tough to tumble. Here is are a couple methods that might work for you:

Wow, that is a beautiful collection of patterns
Very cool. Thank you for sharing. Fossils are so interesting and fun to find. I was geeked to see this pop up on my notifications. Thanks again.
I'm glad it popped up for you too. I have some other fossil videos if you're interested.
@@MichiganRocks Bring them on !!!
@@davidhile5363 ruclips.net/p/PLqNINgwEkm-IKR7-fU-ILoYG4mpv0Czqt
@@MichiganRocks thanks I will watch.
Was it just me.... it seemed that most of these were quite a bit larger in size than the rocks you share with us? Excellent show my friend, excellent indeed!
I don't think they're larger than most of the rocks I show you. Some of the favosites were a little bigger maybe.
Very cool fossils! Thanks for sharing😊
You're welcome, Julie.
Hello, do you think you could do a video on how to tumble petoskeys in only a roudery tumbler
Maybe I can do that one of these days.
Hi Rob. I'm always interested in fossils. It is just neat to think you are holding something that was once alive millions of year ago. Anyway, do you think the light and dark banding on some of these rocks (0:50 for example) is indicative of a pattern of annual growth?
I have no idea what makes those bands. I'd love to know though.
I wondered that, too. Makes sense. Trees have rings...🤷🏻♀️😃
Thank you for sharing. Awesome fossils
How old are these fossil stones? They polished up beautifully! How long did you have to tumble these fossils to get them that smooth?
These are Devonian period fossils, about 350-360 million years old. They were all tumbled.
Those fossils look good, so many intricate patterns in them, would be great to have some much larger rocks polished up also.
I have a big cladopora partially polished with my handheld wet stone grinder. It's probably ten inches across. It was almost done and I chunk broke off the top. I got frustrated and put it away and haven't gotten back to it. Sometimes cladopora is pretty fractured and other times it's really solid. I'm afraid that more of the big one is going to break off.
@@MichiganRocks oh really, that's such a shame. Maybe you might find another large piece on one of your adventures.
@@tonywild1963 Darn, that means I might need to spend some time on the beach again. Bummer.
Luv my fossils👍 Beautiful ❤️ Thank you for sharing your knowledge and skills.
You're welcome!
nice work...nice rocks
Thanks!
So Pretty Thank You so much for sharing your knowledge.. talent and beautiful treasures with us!!
You're welcome. Thanks for watching.
Great videos. I watched your video about tumbling Petoskey stones. Do you tumble Charlevoix stones the same a Petoskey stones?
Yep, they're both limestone, so they tumble the same way.
Nice 👍 The orange peel effect is different but still pretty.
I don't mind that look at all.
Very unique stones of fossils.
The fossils are super fun !!
They sure can be beautiful.
Beautiful, cracks or no. I assume these are limestone? Pretty soft. TFS 💖🦅🦅
Yes, mostly limestone. I don't know what the black matrix of the cladopora is.
If you dont mind me asking .How did you polish the fossils I havent had any luck . Did you use the corncob media method ?
These fossils are mostly limestone, so the corn cob method should work on them just like it does with Petoskey stones. I have found that horn coral tends to have little voids in them, so they don’t usually turn out as well. I have seen others on
Facebook do well with horn coral though, so the material must vary.
Honeycomb probably! I have a banded chert that didn't polish well too. Other chert was shiny. Go figure.
Love the fossil forms-- especially the hexagonal patterns. I'm wondering why there's never any trace of color? I understand fossils form when surrounding minerals replace the hard body parts (shells, bones, etc.) But why are those replacement minerals always shades of gray, without color?
Around here, it's because it's limestone, which is typically gray. In Rockport Quarry, almost everything is gray or black, but there are tiny fragments of a prehistoric fish that are a fairly bright blue. They're not very easy to find. They find horn coral in Utah that is red.
Where in Utah, Rob? I have family out there. Of course, when you go down around St. George and Zion, all the base rock is red! Beautiful!
Also, loved the fossils, really cool.
Those are so cool !!! I’ve heard many people refer toCharlavoix stone as honeycomb coral and then you have the ones like at 2:53 that look like honey comb coral also. Not sure which one is which. I’ve drilled holes in the black stone and smelled the oil. Manistee Count is the largest oil producing county in the state of Michigan. They do what they call slant drilling, where the oil well head is on land but the actual well is under Lake Michigan.
I guess that makes sense. We have a lot of gas wells on this side of the state. I'm not sure how many oil wells we have. I know shale can contain oil, but I don't think this black matrix is shale. It's not in layers like shale is.
I just found this gas and oil map. Pretty interesting. www.michigan.gov/documents/deq/MICHIGAN_OIL_GAS_MAP_411600_7.pdf
@@MichiganRocks In the city of Manistee is a building where they process natural gas I suppose to remove impurities. I don’t know what kind of equipment is in there but on the outside it sounds like a railroad locomotive idling. Must be some kind of compressors or something.
@@davidhile5363 Sound like something I don't want in my backyard.
@@MichiganRocks Yeah, no kidding !!!
Amazing stone's. 👌
These are absolutely beautiful, Rob.
Geez, my fossils suck.
Maybe they just need some lovin'.
Awesome fossils Rob
Only a rock guy can understand why someone would spend almost 9 minutes watching someone showing rocks in a box. I understand! 😂
These videos are sure not for everyone. I'm glad you like them though.
@@MichiganRocks My daughter always makes fun of me for watching a video of a guy talking about his rocks. She doesn't get the addiction. Same goes for my metal detecting addiction.
@@jimknarr You know, you are probably the strange one of the two of you. This sort of content is not exactly mainstream. On the other hand, who cares what the darn kids think?
Those are Awesome!!!
I love fossils, it was so cool to see all the different kinds of coral. The bands in the favosites coral looked similar to the bands in banded chert. The fossil at 2:53 looks really similar to petoskey stone, and the fossil at 3:53 looks like it might be parts of a mollusk shell , like a muscle or a scallop. I also thought the horn coral was cool because each piece was different . I also enjoyed the tiny fossils in amongst the black matrix.
That rock at 2:53 does look very similar to Petoskey, but with smaller coral polyps. Lots of fun fossils in these boxes.
@@MichiganRocks Indeed .😍🥰😇💜💙💚
Now that's a rockin family....thank you.
Hello! I am wondering how to get the fossils shiny if they are already smooth? I have watched several of your videos and need to know the best way to make them shiny. Thanks!! I’m collecting specimens From Lake Erie!
Here are a few videos showing methods for polishing Petoskey Stones. They also work on other limestone fossils.

I think I will give this a try with some of my fossils, they turned out amazing 😍
Good luck!
Very pretty Rocks
God makes some cool stuff.
Okay, I have more questions. Just how old are the fossils? I thought the great lakes were formed after the ice age ten thousand years ago? Why was coral around, in the lakes, after the ice age? Prior to the ice age, what was the land like up there in Michigan?
This area used to be a shallow sea. I have never heard what "shallow" is defined as, but that's how it's always described. These fossils are from the Devonian period, 350 or 360 million years ago.
Thank you. 😁
Corals are the coolest.
I love your rocks
These are very cool
I was just wondering, are these some stones that you just polished recently or are they from days gone by ?
These are not recent tumbles. They are also not from a single batch. They have been accumulating over the years.
The fossils are beautiful
Did you tumble those? I've found numerous fossils and am not sure how to finish them.
I hand polish Petosky stones but have too many other fossils to hand finish and not sure if they can be hand finished without losing detail.
Please advise.
I haven't tried to polish fossils like brachiopods, for example. I think they would lose all their fossilness if you ground off the shells. I imagine it would just be gray rock underneath. Corals seem to be a safe fossil to tumble because the pattern goes right through the whole rock.
Gorgeous! Love 'em!
what made you decide to polish your fossils? Love this video series and the slide show at the end.
The Petoskey Stone is the state stone of Michigan. It's a fossil coral and polishes nicely. Since all of these are made of limestone just like Petoskey stones, I figured they'd polish up well too.
@@MichiganRocks Interesting. And it turned out to be true - they did polish up nicely. Thanks for sharing.
You might have better luck polishing the fossils if you treat them first. Paleo joe uses cyanoacrylate, the thin type, and some acetone solution. It would stabilize the carbon matrix, the little holes would be closed. Just a thought.
I have heard of doing that, but never tried myself. I was actually pretty happy with the polish I got on these without soaking them in superglue.
@@MichiganRocks well, the acetone sealer is what museums use, and fossils have to be preserved or they crumble when exposed to a dryer environment. I like the ones that aren’t perfect. 🤓they have character.
About how long do you leave these in first stage? I have a lot of these same types of fossils and wanted to try to tumble some as well.
I run rocks like these for 3-4 days at a time in the first stage. Here's a video showing the first two stages for tumbling Petoskey stones. These can be done the same way.
ruclips.net/video/IBRq7dPD0Lk/видео.html
I love fossils, thanks
Can you tumble charlevoix stones with petoskey stones or are they a different hardness?
They tumble the same and there's no problem mixing them in my experience.
Love this video
Thanks, Jim!
Are these done in rotary tumbler or the Lot O? Do you have a general recipe for these?
These were from many different batches, but stored together because they're all fossils. Some day, I'll probably do a video on the method. It's not my normal method. These are done in a rotary from start to finish.
The polish on the "rough" surfaces really shows off the vibro
These were probably mostly done in a rotary.
These are my favorite so far. I really like Petoskey stones, but these are so unique. Well done!
Petoskeys are my favorite, but there are some other great fossils out there too.
