My Dad found this about 15 years ago while hiking or hunting one. But he was always sure it was a fossil of some ocean creature. Let me know what you all think it is bc I have no idea.

is this a fossilized seed of some kind or am i crazy - it , to my best knowledge, seems to be solid stone

I thought it was a sand dollar at first, but then realized it’s a rock. Any information would be amazing. Thank you

Still quite shaky over finding this huge tooth! Just curious if it's possible to tell if this isn't an upper or lower tooth and would love any advice on preserving it or if that is something I should leave to someone more experienced in preservation. It is very fragile, missing some of the chewing surface and unfortunately a small piece broke off when my shovel hit it. It is roughly 13" long and has 13 plates.

I am afraid to handle it too much so the photos aren't great.

Purchased in Minnesota, unsure where it originated. It’s quite solid/heavy. There is some surface chipping- how can I best preserve it? I haven’t licked it or done any testing on it.

Some time ago I noticed that the tiles at the entrance of my block were absolutely teeming with these rocky critters.

I thought on posting these to see if the fossil freaks could find some interesting details and things that I haven't noticed yet, so have fun looking at them!

Most of them are around the size of a coin, but a few ones could get up to 10x times bigger or even more.

Location: the floor is in northem Andalusia, Spain. I believe that the place of origin of the tiles is there too, as the sea of Thetis used to flood that region

Found this a while back! Never really found out what it is… any ideas? And sorry this was the only photo I could find when I still had it in the matrix..

This was given to me by my grandmother way back in the early 70s. Just wondering what type of shark and how old it could possibly be.

Been excavating around one or more Limestone shelves, and from a probe hole i dug, this shape stood out.

I have a strong belief that Limestone from this spot has dissolved away over time to become much of the Clay beneath. I've found enough variety of stone nearby to suggest some washing down/collapse in a ~4' radius of this spot. At the depth of this fossil i also picked out an extremely dark blue piece of Limestone, darker and harder than any ive excavated so far. Thoughts? TIA

Hi all. Not the most aesthetically pleasing, but I pulled this out of shale in a southern Ohio creekbed. I believe there is some bryozoan in here but what else is notable?

Found this in El Paso, TX, in a parking lot that used river rock for landscaping. I don't imagine there's enough here to identify what it came from, just wondering if it's a fossil. It feels light for a rock, and it felt kind of tacky after I washed it.

This is a rock I found off of rt 24 in Utah, outside of Capitol Reef np, north of the Fremont river near the entrance to Cathedral Valley.

The matrix rock is grainy. The inclusions are tubular, raised, hard, smooth, waxy, and translucent in parts. They have banding that follows the boundary of the inclusion.

The last photo is of a naturally broken face in the rock.

Picture is of wet rock.

What could it be?

Happy to answer any questions that might help in ID.

What is it, i am certain its a tooth not a fossil but what animal is it from if someone knows

Thanks u

Found in the mountains of Meeker CO. What little knowledge of fossil hunting tells me it is a fossil but can’t be sure. Any help is appreciated

I found these two fossils on my latest trip, according to the sparse geological information I was able to find the sediment rock should be from Cretaceous, I presume both to be from some bivalve mollusks, but I came to ask if anyone is able to provide a more detailed id than just “bivalve” as I am very new to the hobby.
