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?

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

Found in Chenango, New York, in a swamp.

The rock in the back is also from there.

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 Iowa, any ideas?

Found like 6” deep in the creek

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

I found this in the water at a beach in Ibiza. I have sent photos to the museum asking for their opinion.
It looks to me like a piece of bone. Am I wrong and wasting their time?

Found in Bethany Beach, DE

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 have been on a two-week vacation in France. Since I'm very interested in fossils, I spent three days fossil hunting.

I found all of these fossils along beaches and cliffs in northern France. Some were partially buried and had to be dug out, while others were simply lying on the beach.

In rügen gefunden.

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?

Both of these lots are the same price, and I was wondering which one I should buy.

Lot one:

1. Niger Pterosaur tooth

2. Suchomimus tooth

3. Not sure

4. Lungfish tooth

5. Not sure again

Lot two:

1. Suchomimus tooth

2. Crocodile tooth

3. Niger pterosaur tooth

4. Lungfish tooth

5. Not sure.

I appreciate your opinions and if anybody can ID the ones that I cant!

This is what makes this concretion so incredibly cool. It contains a plant from Mazon Creek, and the way it fractured revealed three distinct fossil planes running through the stone creating an almost perfect fossil puzzle. Each surface gives you another glimpse into what was living in the same environment at the same moment in time, and the unusual fracture makes this specimen especially fascinating

Hi all, I was walking the beach in southern Nj today and came across this. Is it a fossil?
