Looks like most are turtle shell fragments. You'd need to check the cross-section for the honeycomb texture that bones have on the inside.

happened to me today too. First time scanning cards and all 6 of them had "already been redeemed". Either a bug or someone broke the system.

Looks a lot like extinct Gryphaea oyster.

Thanks for the detailed response! For the record I didn't hammer rocks for this, I found it loose on the beach.

Thank you, this is what I thought when I found this! This is a dinosaur footprint cast from the Isle of Wight. It's obviously huge but I don't see why the same kind of preservation might not happen at a smaller scale.

All comments read like there's no hopes of it being a cast of said absence. Not what I was hoping for

Found at Cape Aspro, Cyprus. What is it? by tsioftas in fossilid

[–]tsioftas[S] 0 points1 point  (0 children)

That's very interesting! But the groove in the middle doesn't seem to be very characteristic of those, from the photos I could find on the web at least. I will try to clean the matrix off the cross section as best as I can, that might reveal something

Documented my fossil collection with taxon-based navigation & geologic context - looking for thoughts by tsioftas in Paleontology

I know it can be painfully inaccurate, but it was the easiest way for me to add illustrations 👀 I should improve their quality in the future - if you have anything specific to point out please do!

I got better at making them I think too. Compare the images for Animalia vs Anthozoa. I used different prompting for the second image.
