I found it in a creek.

Found on Lake Michigan by my son, are the fossil concretions?

genuinely one of the hardest photogrammetry scans i’ve done, because of the size, but now i know how to scan very small objects!

So my family was in a zoo on that mountain called Hochlantsch. And in the parking lot already my son found a rock looking like petrified wood. Looked like but I wasn't sure, said, if we already found this, there had to be more. Well, we found some more... Even a piece that looks like it had woodworms. Some minerals we'll have to check later, too.

Oh, and there was so much of these, those few we took won't be missed, I think/hope. People were actually walking on them and they were all around, they broke the rock for the from rubble built trail. We could see the layers of stone and inbetween there were brown trees. No one looked at these, no one seemed to be aware. Not even a sign was there.

Found this in shell limestone at a location (near Berlin) known for nothosaur fossils but the roundness of it makes me think it’s something else, any ideas?

I was at Myrtle Beach (South Carolina), and I was digging in the sand since I was looking for shark teeth, then I found this, but it looked interesting, so I put it in my pocket, but I don't know how to tell fossils yet, so if you can, let me know what this is

Bought two Mosasaur teeth at a fair for the kids. Are they real? Any idea where they were found? How old are they? The woman selling didn't know anything.

I've found this on a beach, likely brought to shore by sea currents.

Mediterranean Sea if that matters.

(Last picture it's the bottom)

I don’t know might be something cool

Found on Lea Island in NC.

Found these in my grandmothers collection of her shells. Any ideas?

My student found this rock, came asking if it was a fossil. Is it anything? Or is it just corrosion?

From the Volga riverbank near Ulyanovsk

Found on top of terminal moraine (last ice age) in Nijmegen, the Netherlands. I suspect a tooth fragment but if that's true, and if so of what animal... clueless

Ventured into the Newark Super Group. Found some Upper Triassic aged fossils from the Lockatong Formation in SE Pennsylvania. Specifically Conchostracan, or Clam Shrimp. These are bivalved crustaceans that lived in a freshwater environment. Also included a couple photos of non-fossilized animals spotted on the trip.

What yall tink

Does anybody know what this is? Found on a stoney beach with lots of limestone. Feels very heavy but is non magnetic

Very well preserved early jurassic ammonite extracted from the Enzesfeld deposits found in the Vienna Forest. Somewhere between 195 and 200 million years old. Prepped over the last couple of weekends.

I’d like to ask for your help with the identification of this fossil. I found it twenty years ago in northern Poland near Gdansk and kept it in the drawer since then. I picked it up by a lake which was formed by glaciers if that’s of any importance.
The stone is approximately 3 cm in each direction.
Thanks!

Found near Lyme Regis.

Found this is the Sulphur River in North Texas. Some people have found whole intact specimens in the walls.
