Hello, new to the world of fossils and would appreciate any help with identification or even if it's possible to id with just one example? I hope so.

What is the general location of where it was found?

I don't see a fossil. Is it the entire item? If embedded in the item, can you point out the fossil itself? I do see a weird sort of texture. Not sure if it's organic or geological.

It's hard to tell by the pic but it has a lot of processes, a flat scapula area, possible foramen and articulating sites. I have just enough bioarchaeology experience to know its a bone.

Thanks for the help.

So, what bone(s) would this specimen correspond to on a human? I know a scapula is a shoulder blade, foramen is a hole for a nerve bundle, and articulating site would be some sort of joint or flex point.

I think a clear, hires shot of the chipped areas showing the internal structure might help experts confirm it's a fossil bone. I assume you don't think it's a cast of a bone.

Reminds me of the joints of a turtle.

OK. On a human scapula, there's a notch, but no foramen per se. I don't think there's a foramen on a turtle scapula. It looks a lot simpler than the human version to me. What turtle bone (or process) is the closest match to your specimen, do you think?

Hope this helps.

Can you point out the anatomical features you mentioned, e.g. scapula, foramen, articulating sites? I suppose you could stick little bits of white tape with numbers or something.

Based on these photos, this piece doesn't appear to be bone, or a fossil. Maybe sharper images could provide a different conclusion. :)

Found a mosasaur vertebrae online with the same weird coloring and pattern from the same location, sulphur river.
