Anyone able to help me identify this rock? I picked it up years ago because i just thought it looked cool, but I found it again recently and began wondering if it could be a plant fossil.

Thats clearly a frog

I'll plant my rock in your fossil m8

Are you sure?

Absolutely you can see the webbing on the arches

looks more like the shell of a turtle

Looks like basalt with fossilized lillies.

Looks like a variation of a petoskey stone:
en.wikipedia.org/wiki/Petoskey_stone

it's colonial rugose coral in there, pic related
technically it's a fossiliferous packstone, since it's grain-supported rather than mud-supported. note also that the corallites appear to be filled in with calcite spar, but I can't see the crystals closely enough to tell you whether that spar formed in marine or freshwater conditions.

>fossils in igneous rock
back 2 intro geo for you

this man is basically correct

It just looks like a rock that used to have mussels attached to it. I'm from Chile so I see these a lot when I want to go eat a fresh snack ;^)

Basalt is igneous you fossil

Do some x-ray fluorescence on it, mate.

I want to get into petroleum geology

Are you a working geologist by any chance?

I would assume freshwater as I found it in a riverbed, thanks for the help!

It looks like seeds,

Kinda looks like a Petosky stone.

Well you would assume incorrectly. Rocks very rarely are formed in the location that you found them in.

Since this has coral in it (as correctly identified), specifically rugose, this was likely formed sometime in the Ordovician. Did you happen to find this in the midwest?

On second thought, it's more likely solitary rugose corals growing closely together. maybe some kind of bafflestone.

rugose corals were entirely marine IIRC. like said, where did you find this?

no, I'm a grad student doing paleo. most of my classmates are doing

Geologist here.

It is a skeletal packstone

I have a phobia for frogs, and more this. I wish your family gets sodomized in front of you, while you can do nothing but watch, cry and scream

It's limestone with coral fossils.

Drake, do you really think this is the best place for advice on rocks?

>still using Folk and Dunham instead of the objectively superior Wright classification

It's just a piece of ancient poop.

Oh God, this reminds me of some unlucky shit

turns out I had a half pound chunk of carnotite sitting in my bedroom for like 6 months. Thankfully, I'm not a massive chunk of tumors, yet.

>being a frogphobic bigot
>current year

I'm trypophobic, what the hell is that?
Sodomized with a fucking cactus my friend.

What did you did with the rock?

dubs confirm its a rock

I got rid of it, I regret doing it now, I could safely keep it outdoors in a metal can easily enough, but I was pretty unnerved by the whole thing, I don't really fuck around with rocks much anymore

Stop.

Holy shit, that's amazing.

They're crinoid fossils

Unlucky because you didn't know what it was, but man finding carnotite is a dream of mine. I'm a hobbyist mineral collector and I've always dreamed of finding carnotite or other Uranium-containing minerals. Thankfully I live beneath Carbon County, Pa. Hoping to find some this summer.
