You never know what you will get until you cut them open, LOL. These are from the early Cretaceous, approximately 120 million years old. Most Utah septarian deposits are late cretaceous 70 million years old. Our nodules formed around tree roots ss the land became more arid, allowing the soil to crack. Then, creating voids around the roots. These voids eventually filled in with the minerals to form the nodules.
Thanks for adding the additional information! I know you wrote that in your letter, but I was trying to keep the video short. I'll pin your comment so more people will see it. Thanks again.
I've been out of town for the past two and a half weeks, and this is the first thing I did when I got home today. I'll play with the other material another day.
@@MichiganRocks Yesterday I found a lightning stone in a creek in Northeast Ohio. I'm assuming it must be glacial deposited pushed south from Canada? Have you heard of them being natural to the southern Lake Erie shore?
Have you ever thought about making spheres of some of your finds? This would be a neat sphere, small ones like marble size or something a little bigger. Just an idea, great video by the way.
Yes, I asked a company to donate a small sphere machine to my channel recently, but they turned me down. I am seriously thinking about building one. I think I'd rather make about one inch spheres rather than big ones. Less time cutting, smaller rocks, and it would be easier to display a bunch of them in a bowl or something.
I never heard of this stone, but anytime you get to use the UV light, I think it is pretty cool. Are there any fossils that you know of that glow under UV?
I've seen Montana rockhounds pick up septarians on RUclips but never saw them cut. Will you be polishing these? I found some information about their formation, pretty interesting. And pretty old! Thanks Rob 👍🏻
I don't have a great way to polish something as big as the larger one. I have been thinking about getting a vibrating flat lap which would be perfect for doing these.
Hi. Thank you for sharing your knowledge! I've been watching your vids & others on the best rock tumblers, along with searching the best rock tumblers. But, I am still uncertain which to buy. As I am just a hobbyist & a beach comber type, I only want to spend between 150 - 200 Canadian. And I live in an apt building. I think a two barrel tumbler would be a good thing. Main thing is I'd want to get a great polish without too many failures. Can you help? Ps: And which grit too?
That question has recently gotten tougher to answer. I'd spend the money on a Lortone 33B, or 3A if you can't afford the 33B. The problem is that they recently announced that they're going out of business. I think Kingsley North still has some in stock though. Using good grit, especially polish, is important. Both Kingsley North and the Rock Shed sell great polish at really good prices, especially if you buy larger quantities. You can find links to both stores in the descriptions of any of my videos. I'm not sure who to recommend that you buy from in Canada though.
Hey, I'm a newbie rock tumbler. Just finished watching your 8 tips for beginners video which was very enlightening. This may sound lame but how much should I wash or clean the rocks before I start the tumbling process?

@MichiganRocks They do take a great polish. for the bigger ones we have been getting the best results with a high rpm dry sander.
@@Serpents-Ridege-Lapidary Maybe I'll give it a try this summer. That's an outside job.
@@MichiganRocks yes, outside with a good respirator.
These are cool. I like the second one as well. I need to cut open the nodules I got from him too.
I've been out of town for the past two and a half weeks, and this is the first thing I did when I got home today. I'll play with the other material another day.
Neat looking on the inside.
Love the big one. Septarian are among my favorites.
Gorgeous rocks!
Love these! Very different from what I expected. Thanks for sharing.
Love it. They both remind me of an MRI scan.
Cool! They also have hints of blue in it.
The blue specks are dust. They wipe right off.
Oh, those are really beautiful cutted❤and the fluorence is so cool👍👋🇫🇮
The large one was beautiful.
That's wierd, I just seen someone on reddit ask what those type of rocks were. Now I know, lol.
I'm here just when you need me!
Those i find in Denmark too. I've just made 3 of them in too heart shapes. lovely stone too work, soft and forgiving :)
We also have similar septarian nodules in Michigan. Ours are soft too, but take a nice polish.
I agree the second one was nicer but the orange is nice 😊
Too bad we couldn't move that orange color to the other rock, huh?
@@MichiganRocks Agreed 👍
The little one has pictures inside that looks like birds looking sideways at each other. Cool rocks though, how awesome is nature.
I was gonna make a smartass comment until I saw the first one, it does look like a bird lol
I rarely see stuff like that. Thanks for pointing it out!
It reminds me a lot of lightning stone.
Lightning stone is also a septarian nodule, so they're the same thing from different locations.
@@MichiganRocks Yesterday I found a lightning stone in a creek in Northeast Ohio. I'm assuming it must be glacial deposited pushed south from Canada? Have you heard of them being natural to the southern Lake Erie shore?
@@ganggreen9012 The only place I have found them is in Lake Michigan in the southwestern part of the state.
Interesting.
Fun!❤

@@MichiganRocks I'd love to see your build of one, agate marbles would look nice
@@Absolution55 If I make one, you'll see a video, that's for sure.
The next trip you need to take is the moon...I hear there is some nice stuff there. (Utah made me think of the moon :)
There is also fields of opal on Mars
That might be slightly out of my price range. Maybe I can do some sort of collaboration with Elon Musk.
😂😂😂😂😂😂😂
@@MichiganRocks do it 😂
They kind of look like a petrified cow patty but they look pretty neat inside especially the large one.
You've heard of coprolite, right?
I have a few small rocks like these,... They sort of remind me of a pile of poop! Ha ha! Nodules! 😂
There is such a thing as fossilized poop, it's called coprolite. This isn't that, though.
Nice, although I prefer Michigan septarian or lightning stones.
I do too.
I never heard of this stone, but anytime you get to use the UV light, I think it is pretty cool. Are there any fossils that you know of that glow under UV?
Petoskey stones glow about like these do. It's the calcite in both that glow. ruclips.net/user/shortsMESDmmC5Ssg

The second one looks green through the camera lens. Maybe teal/aqua.
It looked yellow in person.
It looks green on my screen too.

I'd just rinse off any dirt. Any other dirt will get tumbled off very quickly. It's not something to worry about at all.
Thank you so much!
My septarian specimens are not only fluorescent, but also mildly phosphorescent.
Ooh! I didn't try that. I shouldn't be surprised because Petoskey stones, which are also calcite are slightly phosphorescent.
What mineral makes one glow yellow and the other one glow orange?
Calcite.
Rob, if you polish those nodules, would they take a good shine?
I don't know, but the lightning stone from Michigan is a septarian nodule and it polished up nicely.
🙋♀️❤️
Is it just me or does the center of the big one look like an embryo curled up 8n side it?
You think it's a big egg?
@@MichiganRocks no😂, just that the positioning of the elements looks like a squished embryo.
👁👁 😋 …👏👏 1:46
Wow, that second one is really awesome! Nice of them to send u some goodness :)
The second one was amazing. Cut in half, they look like the footprints you'd leave in the sand
I thought one looked like a footprint too.
Very cool! The larger one did have a more interesting pattern and fluorescent color.
The yellow one is pretty cool.
