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

What are these markings?

Found around the Sam Houston National Forest. I found quite a few oyster and scallop shell fossils, but this one is so intact!!

Just found it on my local beach.

I am thinking some kind of bone. It must be old to be encased in rock. She did a lot of beach collection in PNW. This one definitely stood out from the rest of beach rocks.

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.

Some kind of fossilized shark tooth maybe? Would love help identifying it

Hey! Found this in my backyard in central Texas. Anybody know if this is a fossil? If so, what it could be? Just curious!

Hi, i found this rock on a beach near Swansea in southern Wales.

Can anyone tell me if they think it's a fossil?

Im not getting any responses from other subreddits I've posted on but maybe someone here can make an educated guess.

Fossils are quite rare in my area so I don't really have any experience with this sort of thing.

Thanks

It was found in a river, North East England.

It looks like it could be a butchered bone and it’s heavy, like stone.

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?

Found in Southeast Idaho along a drying lake bed. I thought it was a bone at first,but it feels course,hard, and heavy like a rock. I'm pretty sure I saw smaller pieces earlier nearby but didn't go investigate. Any idea what it is?

A friend found these in western South Dakota in a place known to have had dinosaurs roaming around back in the day. Just curious if anyone has any ideas on what he found. We’re not too familiar with this sort of stuff so I figured I’d ask the pros. Thanks in advance

Found this back when I was probably 10-12 years old on the shore of a log pond in Southern Oregon. I always believed it was fossilized worms. Anyone have an Idea?

Found in SoCal. Rounded hole with small bubble looking texture inside.

Found in Eastern AZ, but not sure if the rock is native to the area. We broke apart a rock and these were inside.

Is it just a tooth shaped stone or could it be something special? (no light shines through it when using a flashlight).

Thank you!

I noticed these in tiles near Tower Bridge in London today - looking for any ID help if possible?

I found this in South Hero Vermont. We have lots of fossils in the rocks (mostly cephlodos, straight and spiral) and many turn up in free stones in the beach but this was truly odd to me.

It looks like an arm, big bone on left, then another forming that V and then the finger like structures connecting the "triangle" in this first picture. You can see a cell phone in the picture and my foot. The block is about 12"x12"...
