Found this in montaña de oro, California. Curious if anyone can ID the plant. I told my aunt who is a marine biologist in the area and she told me plant fossils are rare on this part of the coast.

I found this impression of a sea urchin on a rock at Étretat, Normandy. I reasoned that that was where it belonged and did not carry it home.

Gemini said that it likely belongs to an extinct species of sea urchin.

"Fossil imprint of a cidarid sea urchin embedded within a weathered flint pebble.

A cidarid echinoid (pencil sea urchin), with features highly consistent with Stereocidaris sceptrifera (or a closely related genus like Tylocidaris) from the Late Cretaceous period (around 80–90 million years old)."

Found at local thrift store. Ammonite measures ~4 cm.

I had a bottle of knob creek and a football for scale. I found them eroding out of a bedrock ledge in a creek that runs through my buddy’s property. (SE Oklahoma)

I found this in a seasonal creek where I regularly find sand dollar, snail, and clam fossils. I have never before found anything like this, my best guess is it’s a tooth but whose tooth could it be?

Found on the beach outside of Charleston, C. What is it?

Found on Myrtle Beach, SC

Found this strange object in the mud in a cave in northern Thailand. Unsure if this is just a concretion of fallen stalactites or if it is some kind of fossil. Left it with a local caving guide after cleaning it up.

I was given this alleged T. Rex tooth by a friend, but I have my doubts. Is there any way to be sure?

I did lick it, and it has a similar texture to my own teeth, if that helps.

Thanks in advance 🦖

Any idea if this is a fossil or just a rock with strange patterns?

Hey fossil identifying people! While looking at some rocks by the cabin I was staying at this past weekend I kept finding rocks with this weird bowl-like shape to them. I cracked one open and inside it looks like it has some kind of radiating structure to the inside that seemed fossil-like to me? Or maybe it’s a kind of rock I just don’t recognize lol. Would appreciate any help I can get!

Hello all,

Interested in this specimen, which the seller says is Apatorhamphus jaw material, and I just wanted to make sure that it isn't a composite or something.

They made mention of some glued repairs which made me worried of the possibility of it being fake.

What do y'all think? Looks authentic to me, but my judgement is worth as much as dehydrated water.

My fiance found this underground at his coal mine job and we aren’t having much luck identifying it! It was found as part of the Herrin coal seam in southern Illinois, Randolph county to be exact

I am having trouble figuring out what this is, and rapidly realizing ChatGPT is pretty hit or miss on this stuff
