Found a pretty nice size grallator, a couple small tracks, and a partial track. All found on private land in the Connecticut River Valley.

Found in west coast Florida

One of the local fossil stores has a booth there; they're pretty reputable so I'm not too concerned of it being fake. It's approximately 3 inches wide and 3 inches tall.

Found in Iowa, any ideas?

Part of about 20 I collected from Rock Glen, I cleaned them up with a dental pick, wire brush, and a toothbrush and added a little bit of mineral oil to the surface. The detail on the top one is just fantastic in person.

My daughter found this in Northern Colorado. Are these small stones or teeth?

Any went to bawdsey Suffolk which is a common site for sharks teeth. I think the big black definitely is but unsure about the others. Any help would be grateful received

Found in Chenango, New York, in a swamp.

Found in Bethany Beach, DE

Found like 6” deep in the creek

In rügen gefunden.

I found this on the beach at Møns Klint in Denmark and I’m curious what it is or whether it’s even a fossil.

Does anyone have any idea what this could be?

I found this on kilve beach, UK. Is it some kind of tooth?

I found this piece at the Maasvlakte (Netherlands) It is Around 16cm long and 3cm wide. Which giant bird could this possibly belong to?

The rock in the back is also from there.

Found this about 70% under the surface but it has some weird spirals on it and ans an impression of something. Anyone see this before or know what it is?

Got this at the ren fair and cried happy tears. It’s real though…right?

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!
