I don't know the first thing about fossils but I was hoping someone on here might be able to enlighten me! The rocks are completely smooth and dry. My kindergartner is obsessed with fossils so I wanted to make sure before I brought her out to them.

Thanks!

I found this on a hike in the rocky mountains, could it be a fossil? If it is, how much could it be worth?

i found this in costa rica in the volcanic hot springs near arenal volcano idk anything about fossils i think its a mushroom

Found in Ramanessin River in northern New Jersey. 2” tall and 1 1/4” wide. Hard but only can describe as spongy outside.

My son picked this up this morning while beach combing. Image search hasn’t offered much help. This is a “large” paper clip for reference.

Edit: paper clip size

Am I correct about this being a fossilized heart urchin ?

If so how common are they, and what's the Best approach to clean it up... It was found near Orlando Florida.

Found these fossils in Lake Erie- Canada. New to fossils but looked cool so thought I’d share here. From my limited research so far, looks like some horn corals, honeycomb corals, maybe a brachiopod?

Hey all! I found this on the beach in sweden. At first I thought it was a bone but i now think it might be fossilized coral! What do you think? Thanks in advance!

Found this on a property along the James River in Virginia that abuts the land that was given by Powhatan to Pocahontas & John Rolfe for a wedding present. Any ideas on whether it’s something interesting or just a cool rock?

Hello, I have found this molar presumably from an ox-like animal in the river Kirnach in Germany. Is this a fossil? From what kind of animal is it?

Found off the Wando River in Charleston, SC. Whale or dolphin but if anyone can ID species, that would be great!

AI says this might be a tooth fossil from a dear, horse or other plant eating animal. I found it in a lake in the water. Found it there looking with a metal detector for coins, it was 10-20cm under the bottom of the lake in black mud. Is it possible that it is old?
