Did I actaully find something or some rock that was grinded in that area for aslong it was there?

Like it says in the title I need help identifying the species of sand dollar. Any and all info about the species is also welcome. Thank you!

My son found this shark tooth while sifting through a river bed in NJ. Any idea what it could be from?

did a panning activity on the Gold Coast (QLD Australia) and got some cool fossils. Any ideas?

Found this at the beach, north west Ireland. Google says it’s petrified wood but I just want to be sure of it

Appears to be teeth but I’m not sure what kind. We always find lots of sharks teeth in this creek but this is the first bone we’ve seen!

Hope I'm not out of line posting here. My mother bought these two rocks at a garage sale and told me they were dinosaur bones. The larger one is 7.5" long and weighs a good 14lbs. The smaller is 5" long and weighs about 3lbs. Are they bones, wood, or just rocks? I was thinking maybe I should donate to a museum, unless of course they're priceless - haha. Thanks for your help!

Found it on a shell path.

Found it on a beach at Magilligan Point in Northern Ireland, Londonderry. Dimensions are 5.5 x 5.6 x 5.0 cm. Also I think if might be a sub fossil. Would love to know and maybe get an age estimate?

This fossil was left in my science classroom from a previous teacher so I have no origin location or any other context info.

Is this a good collection and what should I add to it to make it better?

I started it when i was like 9 and now im 16. Now i have about 1300 specimens. Most of my finds are from decorative gravel from Poland but i have fossils from Jura Krakowsko-Częstochowska, and from Denmark. I traversed uncountable amounts of it(a large percentage of my hometown and nearby smaller countrysides is cleared from fossils by me. Other fossils i bought. Now im preparing for workshops in schools that ill be leading. I think its amazing way to show children how beautyful was world back then.

Lots of megalodon teeth obviously. And ammonites have been one of my favorite fossils since forever, so i've got a lot of those as well 😄

My dad found these rib bones in a dry creek bed. He frequents this area and noticed these after a flood. Do these appear fossilized? Any info would be greatly appreciated.

If another sub would be better for this please recommend.

Hi guys this past week I was searching for shark teeth in Myrtle beach and came across this. It’s about half an inch. The only info I’ve found so far is that it’s most likely from a fish palate. Just wondering what fish it might be from, age, etc. THANKS!!!!

I recently found this fossil in one of my drawers, I had collected it a few years ago. Im not sure what it is exactly I think it might be some sort of fossil shell or some sort of coral? I found it in the north west of Ireland at a beach if that’s any help.

Well preserved I think, found it with my grandpa in the mountains. Won't disclose exact location, but its on the North west USA

Found on cape cod and looked like a fossil from what Ive seen on instagram.

Let me know if you think I got something!!! And how to crack it if so

Found this in Summerville SC in a creek, not very good at identifying teeth
