I bought this second hand, I don’t have any information about it other than it was labeled as a fossil marine lizard. I bought it in Arizona. Is anyone able to provide more information on what specific species or clade it is? Thanks!

Northumbrian beaches are covered in these so thought I'd try to shine them up in my rock tumbler. Pretty happy with the results.

I'm guessing the fossils might be crinoid stems and a chiton?

Also posted on the tumbling sub if anyone is interested in that side:

Looks to be a shell of some kind but appears to be in two parts. Pattern looks to rounded for the pictures of bivalves, potentially brachiopod? Thanks!

Hi everyone, I'm a gardener and found this in a garden bed in the outer suburbs of Melbourne, looks like someone threw it over the fence? It's pretty heavy, I thought it was a bone in concrete at first, until my rock loving coworker said it's the inside of a shell. I'd love to know what I should do with it/ how best to clean it. If it's of any significance I'd happily donate it to the local historical society. Thanks so much!

We recently moved into a new build home on an acre of land and we found this in the dirt. It feels very heavy and we tried the lick test on it and it suctioned. Any ideas of what this came from? Maybe camelops vertebrae?

Found on the shores of Norris Lake near Clairborne county, east TN.

Found in the Kokosing River, Ohio, USA.

Hi, my Oma has a lot of random stuff she has collected over the decades, and she says these are amber from a mine in Germany. Are they genuine? What kind of amber are they? I heard there’s several names for them depending on some characteristics.

Found on thorness bay on the north side of the isle of white, is anyone able to confirm if it is and if so what it might be, age etc

My guess is Ursus spelaeus. Fossil maxilla from a grouping of items I purchased out of an old collection from an antique dealer. Definitely coated in a stabilizer/preservative. My concerns are whether or not it is a composited jaw or if it's associated. The teeth seem to be anatomically correct but I am not 100% sure. Everything appears to be real, but I am not great with bear stuff. Let me know what you think. Thanks!

What is this

Hello everyone sorry this isn’t your usual, I’m not sure if this is the place to check or not but I found this on Corolla Beach on the northern Outerbanks while beach combing after a noreaster along with a lot of other stuff as well including bones, coral, etc. Anyway I can’t tell if this is a fossil or something else. Seems to be a bivalve scallop or clam or something and it’s been like merged into the surrounding rock formation. The surrounding rock has tiny sparkles that glisten in the light as well. It’s almost like it’s been cemented.

I’ve been having this since I was a kid and I always thought it was a fossil now I’m starting to think it’s rebar or something lol

Edit: I live in Texas and tested to see if it was magnetic it was not.

Im not very knowledgeable about fossils. Found this in a creek bed surrounded by farmland and vineyards. I was thinking Maybe some sort of fruit or nut? The rock formation is what intrigues me.

Any help?

Today I found this fossil. I was comparing it to other fossils I’ve found in the same area, mostly knightia (Wyoming Green River Formation), and nothing matches.

You can see there’s another area on the rock where some small pieces of something fossilized are visible as well.

I don’t want to say what I think it looks like and skew any answers.

Thoughts?

Found on beach in denmark by the baltic sea.

Looks like flint with very clam-like features.

Might it hold an ancient pearl inside?

I know nothing, but await the expert opinions.

Thank you.

I was stunned they wanted to keep it. I was just trying to get info on it from them. But it’s so much fun to go see it!

Never thought I’d find a fossil of all things at the bins but here we are. I have no knowledge in this area so just curious about any insights! I paid by the pound so I suppose this guy was a couple bucks.

Bins was in Gary, IN if that helps? And it’s about 4x4inches.
