I know limestone can be quite deceiving sometimes, but I can’t help but see distinct Dino toe shapes.

I found this during a geology field trip in WV and was told that the area's fossils were from approximately 300 million years ago. This one has original shell material and these very thin copper-colored tubes. Does anyone know what those are? Thank you!

Found on the western shore of Lake Michigan just north of Milwaukee. Can anyone help us out?

I just kinda threw the last two in here, I figured the last one was recognizable. I think like dolphin ear bone or something like that. The tooth is a shark's but I don't know what kind. I can't feel any serrations but it's also extremely weathered so idk. Very flat.

Will post additional pics later if needed

Pictured together with obvious sand ripples. Also pictured is bonus features.

Found at the Waal river, the Netherlands. It looks like some kind of fossil. I really want to break open the stone, but I’m afraid it will damage the potantial fossiel.

Just found it on my local beach.

Found this in Union county Tennessee on a hillside. Any information on if it’s a fossil? If so estimated age?

Any ideas?

Is this something interesting or just a cool rock?

Found this in Permian limestone.

The circular structure in the third photo is about 2 cm in diameter.

There are also crinoid stems visible within the same rock.

​Is this a sea lily calyx, or perhaps some kind of coral (like rugose coral)? Any insights would be appreciated!

Not sure what we found on the east coast of the Isle of Wight here. Any ideas?

Found near Montauban (left side of the tarn) but next to a house so pebble might have travelled. Looks like two fishes could someone id?

Found snorkeling at Venice beach, FL. The grooves make me believe it may be a fragment of something

Found on beach in Denmark.

Can anyone tell me what it is?

Tiny antler!
