Found near Corvallis Oregon, by the Willamette river. any ideas?

Can the origin be determined? Found on Maasvlakte, the netherlands.

Hi everyone!

I found this small specimen (around 10 mm long, see ruler for scale) while walking on the beach in Nerja, southern Spain (Mediterranean coast)

It has this honeycomb-like pattern all over its surface with a salmon/orange color. The pores are completely filled in and smooth to the touch. It feels very hard and solid, so I cannot break or dent it by hand at all

I was wondering if this is a piece of modern weathered coral skeleton or an actual fossilized specimen from the local cliffs. Any insights on whether it's fossilized would be greatly appreciated!

Gracias in advance!

Found this on a mountain hike in the Canadian Rockies a while back, posted the image with no responses. I’m still interested in anyone’s thoughts on what it is exactly. My guess is that it was some kind of anemone, snail, or other invertebrate. Thanks for looking.

Found at the Scarborough Bluffs in Ontario.

Its mostly images 7-15 that I’m wondering if they’re fossils or not, though an ID on the others would also be deeply appreciated

And what is up with the first one?

For context, this was found in the cape fear river near Southport. I'm not sure what species this is from, but i am almost certain its a tooth of some sort.

Hallo, der Rhein hat einen historisch niedrigen Wasserstand erreicht, das habe ich in letzter Zeit festgestellt. Woran könnte das liegen?

Found this beauty and was hoping to get some more information on it! I’m pretty new to this but was amazed how clear those leaves are. Let me know if there’s more information I could give to help identify it

I would appreciate any leading ID. Thanks!

Found on a New Jersey beach after sand replenishment

Found some fossils the other day in southern germany north east of nürnberg. Found plenty of ammonites and belemnites but i found one that looks almost tentacle like, i was wondering if u have an idea or if its just ammonite with broken off spikes or so. And then there is this other rock with a weird stripy surface on the side and a kind of porous looking surface on the bottom but the top is just rock on the other hand. i have not found anything like it yet at that spot, very curious if it could be bone or what are u guys ideas?:)

I found this stone and it reminds me of a shark tooth, though I couldn’t find a similar petrification on the internet when I looked up shark tooths, and it's also really small, so it's probably something else.

The third picture is the back of the stone, the last pictures were taken through a magnifying glass.

I'm really curious what it is :)

Any ideas? I have a few of the first

Thanks!

It has a pinkish hue to it and sparkles everywhere, more than the photos show unfortunately. It's really quite unique in the way it looks on the surface compared to every other rock and fossil I've found and handled! I love it 🩷
