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
>>8042791
I'll plant my rock in your fossil m8
>>8042792
Are you sure?
>>8042797
Absolutely you can see the webbing on the arches
>>8042791
looks more like the shell of a turtle
>>8042791
Looks like basalt with fossilized lillies.
>>8042791
Looks like a variation of a 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
>>8042862
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 ;^)
>>8042854
Basalt is igneous you fossil
>>8042791
Do some x-ray fluorescence on it, mate.
>>8044501
I want to get into petroleum geology
Are you a working geologist by any chance?
>>8044501
I would assume freshwater as I found it in a riverbed, thanks for the help!
It looks like seeds,
>>8042791
Kinda looks like a Petosky stone.
On second thought, it's more likely solitary rugose corals growing closely together. maybe some kind of bafflestone.
>>8045100
rugose corals were entirely marine IIRC. like >>8046358 said, where did you find this?
>>8044764
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
>>8042791
It's limestone with coral fossils.

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

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.

I'm trypophobic, what the hell is that?
Sodomized with a fucking cactus my friend.
>>8047006
What did you did with the rock?
>>8047071
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
>>8047084
Stop.
>>8047006
Holy shit, that's amazing.
They're crinoid fossils
>>8047006
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.
