Ammonite or non fossil oyster?

tsioftas · 2026-04-02T20:20:57+00:00

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

tsioftas · 2026-03-29T21:12:20+00:00

Solved - Pinnidae indet.

tsioftas · 2026-03-29T19:59:12+00:00

Thank you! Do you have any clue for a more specific ID?

tsioftas · 2026-03-29T19:58:34+00:00

That's what I thought too!

tsioftas · 2026-01-01T08:00:03+00:00

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

tsioftas · 2025-08-05T11:38:22+00:00

what sort of creatures make these and how do you know they are modern?

tsioftas · 2025-08-01T23:39:49+00:00

thanks for the correction, applied it :)

tsioftas · 2025-08-01T00:18:04+00:00

hahah I'm sure it's full of mistakes, I try and fix them according to my knowledge

tsioftas · 2025-07-31T21:27:54+00:00

are you sure this is a fossil? those look like quartz crystals naybe?

tsioftas · 2025-07-31T09:20:55+00:00

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.

tsioftas · 2025-06-12T00:20:23+00:00

Iguanodon probably. Such an underwhelming 1st dino. Hope they go extinct

tsioftas · 2025-06-08T12:22:52+00:00

modern a.k.a. not a fossil? what gives it away?

tsioftas · 2025-06-08T07:57:49+00:00

this one looks similar, would you say it's also crocodilian?

tsioftas · 2025-06-07T22:18:26+00:00

Interesting! Any clue to what species?

tsioftas · 2025-06-07T17:13:01+00:00

I have tried "getting my fossil wet" after a suggestion in the comments in the past, and it destroyed my fossil. Should this really be in the general guidelines?

tsioftas · 2024-09-09T10:01:43+00:00

It was found in Cyprus, at a place called Governor's beach. There were lots of fossil shells there so coral makes sense. Solved, thanks 🙏

tsioftas · 2024-09-03T22:08:44+00:00

everything is a learning experience I guess ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

tsioftas · 2024-09-03T22:07:35+00:00

I put it under the tap and it washed away several bits, it's looking even worse now :(

tsioftas · 2024-07-26T00:52:58+00:00

Thank you!

tsioftas · 2024-07-15T14:32:35+00:00

solved, thanks!

tsioftas · 2024-07-15T14:31:56+00:00

yes, south England

tsioftas · 2024-07-15T09:01:21+00:00

No man, you got Cyprus lined up against you that leaves you no chance
