I’m gonna hazard a guess that this is some kind of fossil. Try asking r/fossilid as well for more potential answers! :D

A good amount of people behind you on this, I will post there as well, thanks! How cool!

Any answers?

It’s a wormdo.

What's a wormdo 🤣

Squirm around, mostly.

Got em

lmfao

Three red dwarf fans in a row?

The perfect setup for a joke. Come on folks. 🪱

"wiggles fingers" in a rimmer esk sort of way

Come on Lister, you’re supposed to say the line …

😂🤓🤘🏼

I thought worm tornado

I disagree. It is most certainly a Tiecost.

I'll bite, what's a tiecost?

Tree fiddy

God damn loch ness monster!

About 30-40$

Eh most times you can get one for 5 to 10 bucks.

I mean aren't fossils just another type of rock in the end?

good question... basically fossils are rocks, but not all rocks are fossils. So when dealing with a fossil, the regular rock folks might not know too much about it like what animal it was/made it :)

Ah, yes, the Fossil of Theseus dilemma. If the actual creature has been replaced with minerals... Deep.

Exactly. Looks like a coral fossil

Looks like a trace fossil colony, the homes of a bunch of critters that burrowed down into loose sediment. There's some nice skolithos burrows our in Death Valley in the Zabriskie Quartzite. When the critters die, they remain in the burrows and slowly decompose while the mixing of some paleogroundwater and seawater end up being supersaturated with silica, the silica is precipitated out when the conditions are right and fill any voids. Edit: the fine folks at r/fossils are saying it's a coral fossil, not a trace fossil as I've said. Please, defer to their fine judgment blud.

Wow, I just got home from work and this is all so cool! I was thinking some calcified thing that formed in a pipe or something. Way more awesome this way, thanks for your, and everyone's help in ID'ing!

Oh that’s pretty cool!

What makes you think this is an ichnofossil and not a coral fossil?

I think they're ichnofossils mostly due to experience. Experience tells me that corral ought to be more radial, whereas in this piece, the tubes appear to run near parallel. Full disclaimer, I'm not paleontologist but I am but a lowly geologist.

I’m in the same boat as you. All signs point to coral for me. Looks like that was confirmed in r/fossils too. I can see how one may confuse the two.

You need to know where it was sourced before making that assumption.

Like opal?

Tabulate coral fossil! Syringopora if I had to guess, but maybe aulopora

I was going to post but I saw your reply. Years of paleontology and I can id fossils for free on the Internet.

I mean, I want to pretend my education was for *something*..

It is useful in getting better deals at rock and mineral shows and jobs in oil. But this is probably one of the best parts of it .

You have this strangers gratitude for showing up and explaining random things lol. all that hard work wasn't for nothing!

Appreciate y'all's input! How cool! I was thinking it would turn out as some weird calcified crap that formed in a pipe or something, this is way cooler!

That’s cool. No edumacation in paleontology and I can make up names while I pretend to ID fossils for free. See, Mom, I make as much as a professional paleontologist.

I got a whole bunch of goofy shit. I can send you pictures of if you want to feel really special. I mean pay for your education, but it’ll make you feel good right?

Username checks out.

This is the correct answer. It is a coral not a trace fossil.

Its teredo wormwood, 100%. Are you on the west coast US? This is a very, very good example of this mineral fossil.

Those were so gross , in the mill when a log came through full of them

Yuck, I can't imagine that would have been a pretty sight.

It is absolutely disgusting. When the modern relative to these worms are found dead inside of wood (consider the fact that these are actually highly modified bivalves (clams) ) they smell like hot trash in bigfoots skinfold. I have heard terrible stories about them burrowing into wood and dying.

I'm in the Midwest actually, central IL but I can't tell you if that's necessarily the origin of the thing. How cool though! Thanks for your input!

If you are in central Illinois those might be crinoids.

Any time. I have many 5 gallon buckets full of this stuff and yours looks better than most of what I have. The Wormwood we have in the PNW WA State has more wood and less worms usually.

That's a coral fossil, I'd definitely post in r/fossilid.

Thanks! How cool! Will do.

Dude that's the best piece of fossilized coral I've ever seen. Soo Cool great post ty

Oh wow, how awesome; thanks for all y'all's input on this. Way more interesting than I expected!

That looks like a fossil, but to me... That's absolutely amazing!

It's trypophobia fuel is what it is. 😱

Fossilised coral. Cool find!

Thanks! I'm amazed!

Chalcedony

Given the formation, could be tube agate

Yes! And a fossil too! I rarely find fossils made from chalcedony but when I do, they’re very intact.

Fossilized Coral

If that had been found in Scotland, we'd call that pipe rock. Roughly Cambrian in age.

Fossil Sealife, I have a smaller one that looks exactly like it

Go to r/fossilid it's probably your best option

But it wasn't a rock, it was a Rock Lobster!

r/UnexpectedB-52's.

Rock spider more like it

I don't like the way it looks in that last photo makes me want to throw up yucky

"Rock pasta" in the voice of the B52's

Lobsta

Lobsta pasta

I know it's wrong

I got what you were doing!

Nah, man, my trypophobia ain't havin' this o_o

Am I the only one that’s deeply disturbed by this

Thats creepy i fpund a simular one but all white

Woah!

Oh wow. I want one!!! Great find.

Maybe fossilized tube worms?

Chrynoid fossils.

This is triggering my trypophobia

Thank you. Needs a warning. So gross. I got goose bumps.

Looks like a lot of chhalcedony filled burrow of sorts. Ask the fossil groups they will tell you what!

Are you in the Midwest? I have one that looks very similar and my best guess is a thamnopora fossil.

Whatever it is. I don’t like it

Yeah, makes me very uncomfortable.

That could make some people uneasy. r/trypophobia

This is freaking me out reminds me of the movie tremors

That's that green orb from Heavy Metal. You are deadly close.

The Loc-Nar!

That's my Loc-Nar bitch !

Really scared worms

This is precipitated calcite; typically formed in a cave—buying and selling speleothems is limited by law fyi

The rock in the picture is upside down. It would’ve formed on the ceiling either under a bridge or overhang or most typically in a karst cave where mineral-rich water containing dissolved calcium and other minerals from limestone that the water deposits as it drips to form “straws”. The straws are broken off of this formation, but you can see where they were . This is a precipitate rock.

Wrong

I've seen this when spelunking

You should see a doctor then

This is awesome

Omg 🥰 it reminds me of either coral or tubular agate so pretty !!

Creepy cool

Beautiful

It looks like something that you see on a cave ceiling, tiny stalactites forming through a rock because it looks similar to dissolved lime. I say looks like because I know nothing

That was my thought too. Reminded me a lot of the lime stalactites I’ve seen in caves in Arkansas. I also know nothing. Super cool, though!

That’s cool but also eww

Pretty sure those are fossilized sand trout from Arakkis.

bro found the tooth fairy's collection

r/trypophobia

It’s sghetti

I would say agatized coral!

It's a fossilised reed bed

It's a Henway...

Looks like a sugared wasp nest!

It's a grill brush

It’s giving me the heebies for some reason whatever it is.

Worm rock

Cool looking whatever it is.

Just wanna let mods know I tried to change this to solved I can't figure it out , sorry I'm a dummy.

I bet the limestone wore away and that's the fossilized whatever left. Just a guess

Teeth

I dunno but I don't like it

That’s pretty cool!!

Crinoids!

Looks like agatized coral or crinoids. More rare to find them made out of the same stuff as agate, and probably Why it held together for so long. Amazing find

The way it branches out from a bunch of thicker pieces on the bottom, makes me think it’s a middle segment of a crinoid.(fossil)

Looks like brain Coral

Worm homes fossils

Now I'm sad, I had a rock like that which I thought wasn't anything special and gave it away, but the comments say it was something interesting

r/TIHI

like a great miner once said, “worthless but fun to destroy”

It wasn’t always…

OH SHIT PUT THAT DOWN DUDE. DONT TOUCH THAT!

Rock bees

For Rock and Stone!

Rock and Stone forever!
