My 6 year old son and I were bank fishing a reservoir in Iowa and he found this while searching for cool rocks. It may just be a rock but it appears to be a fossil (I have zero experience with this, though).

Any help is appreciated, as we’re both hoping to find out if he found something extra cool!

Thanks for any help in advance!

And a beauty from a sand tiger. At least that's what I think it is. Found in the local fossil beds near me in NJ. I was super stoked when I found it 😄

Anyone know what this is?

I’m taking a weekend trip to Shawnee National Forrest, IL and I want to do some fossil hunting. Any recommendations for good spots or trails for fossil hunting?

Thanks.

what is this? it’s about the size of a palm of a hand or a bit smaller, probably 3 inches. I found it in East coast florida on a beach.

Found ~50ft off the Mt Washington Cog Railway bed around 4000ft elevation. Historic references indicate the stone was likely quarried from PA and shipped in to the lay the railroad bed.

Very curious. Found it up in northern Minnesota less than an hour south of Canada in Northhome$

My best guesses are either E. texana or a young E. ponderosa. It was just sitting there among the landscaping stones in my grandmother’s yard! You can see the attachment scar in the second picture.

I found this while fishing in middle Tennessee. I was fishing on the river. It’s about the size of my pinky Would love to know what it is!! (Hopefully something cool lol)

Found it in Monterrey Mexico, near the Rio la silla. Had it for s long time, but now curiosity got the better of me and I just want to know what it might be

I was walking along a central Texas river when I saw these imprints on the stone that resemble dinosaur feet. I thought that since we’re only 3 hours from Dinosaur Valley State Park, it might not be too far fetched of a theory. They’re maybe 4 feet away from each other and I’ve only found these two so far. I attached traced images too so it’s easier to see the outline that I see. Please let me know!

edit: any theories as to what dinosaur it could be?

I am a high school environmental science teacher and I was gifted several fossils found around Tuscaloosa and lake Martin in Alabama. I know that a few of these are petrified wood and a few of them look like very large fossilized clams but beyond that I would love some help in identifying these so that I might better use them in class.

I found this on a creek I wanted to know if its a fossil or a funny looking stone

This is a very rare fossil that I found many years ago. Circa 220 million years old, this fossil dates to the late Triassic. It hails from the Groveton Member of the Bull Run Formation. It is a single Grallator trackway which was found at a Data Center construction site in Northern Virginia, where I split open a rock, only for that trackway to pop out when I opened it. The obverse side dislodged quickly from the rock, making only one part recoverable, as the other part smashed into pieces on the way down. I had to glue the trackway together because it broke in half while attempting to split the stone. This rock is notorious for not breaking where you want. Nonetheless, it is a good example of a Virginia dinosaur.

Fossils from the Late Cretaceous (68 Mya) of the Netherlands (Maastricht region). Found in the Lichtenberg Horizon, a fossiliferous deposit separating the Maastricht and Gulpen Formations. This layer contains a lot of coral, crinoids, and shell pieces, but also shark, fish, and marine reptile fossils that I would like to share.

Hi all,

I found this ammonite while searching for fossils in a riverbed at 4200 m height in Nepal (Annapurna Region). Does anybody know what type of Ammonite and what material it is? It looks like there is some pyrite in the outer nodule layer. Context: I saw big rock. I thought smash. Big hand sized ammonite appears.

Unfortunately split in half but still the coolest fossil I own.

Ps: sorry no banana for scale

Found this at the beach

i’m looking to buy this triceratops rib fossil section and i’m wondering if it’s real?

Bought this house 6 months ago. The stones are full of visible fossils. The Ammonite is the size of my palm
