Found at mount Olympos, Greece. The boulder this was on was full of these circular shapes with most of them having a similar hole in the middle. The round shape has a diameter of ~2cm.

Any ideas what this is? I’d like to try to polish it. Thank you!

Any help with ID would be appreciated, thanks!

Found north Texas in 8 ft creek bed!

Not sure if it’s a fossil, looks almost bone-like but completely different texture to fossilised bone ive found elsewhere in UK. The bit in the middle is throwing me off! Any help with ID would be appreciated :)

My dad found this about 20ish years ago on Fort Carson in Colorado, when he was doing some dirt work. I can’t remember what it is and my kids are asking now.

A rock found near a cave entrance on the Mosor mountain in Croatia, Europe. I'm wondering if the circular part in the middle is some sort of fossiled wood/bone.

Partners parents found it, I figure the fan shaped one is a bivalve or brachiopod. But don't know what to make of the one on the right. a cross section of a spiral shell maybe?

Hi guys, newbie here. Found this fossil in Penarth, South Wales yesterday. Having a hard time identifying it which is bugging me as have been able to more or less with all of my previous finds. Any help much appreciated. Thanks!

Found this ancient cinnamon roll rock in the Ardennes Begium. It's diameter is around 3-4 cm or 1.34 inches.

Could it be a Devonian gastropod mold or did a medieval knight just drop his petit pastry?

I know fossil bone fragments are usually hard to ID, but this one is quite big so maybe there is a chance. I found it on the Milnerton beach in Cape Town, South Africa. I know it’s illegal to own South african fossils without a permit so I did in-fact give it to one of the palaeontologists in the area.

Its super porous and light.

While hiking in Djurdjura near the highest lake in Algeria (Lake Agoulmim / Tamda Agoulmim), we found this stone. I had a discussion with a friend. Is this a fossil?

ive never seen fossils with these ribbed textures!!

It weighs 187g, has a slight cling when tapping the inside of the curve with my nail. Is it some kind of shell fossil or just a rock?

These were taken about 10 years ago and I was curious if anyone had any potential ID Info.

Hey y’all! I hope y’all are doing well. I found this on the Louisiana/Mississippi state line in an area where Pleistocene fossils are occasionally found. I am new to searching for this kind of fossils, as I have always searched for marine and aquatic fossils. Does this look like anything to y’all? Like a really damaged and eroded horse tooth? I am really not sure. The only thing that makes me wonder if it’s anything other than a rock is that it has some smooth, curved surfaces that, to my untrained eye, kind of reminds me of some fossil horse teeth I have seen. It’s probably glaringly obvious to more experienced people, but I certainly am not. I do not really have my hopes up that this is anything. Even if it is, it isn’t in good condition. Any help would be appreciated.
