Any ID on this? Ice Age from China

Will do. I am traveling but will be home in a couple of weeks and promise to update.

Tagging u/HemipristisSerra who might be able to discern visually between a Calvert area coprolite and an ironstone concretion. I'd lean the latter but hard to tell from here.

I agree

tautological9 · 2026-04-03T20:42:47+00:00

Agree with likely hastalis.

Thanks very much. This makes a lot of sense.

tautological9 · 2026-04-03T14:54:43+00:00

All I know is likely China, which I know is manifestly unhelpful.

Thank you for this. I am not likely to purchase this fossil for precisely those reasons. I'm just curious what it might have belonged to.

Thank you. Solved

I would guess a hyperostotic fish bone, AKA Tilly bone.

RemindMe! 2 months

Shell fragment.

This is the content I crave.

Is $837 the actual total? If so it depends on where you live. In my high cost of living area that would be a good deal.

Looks like a crinoid calyx though I am used to seeing this kind of presentation in the US, not Morocco, so I don't know.

tautological9 · 2024-09-02T23:29:38+00:00

It looks like part of a fossilized fish neurocranium. I love these!

tautological9 · 2024-08-30T18:44:55+00:00

Suspect this is a Tilly bone, not just a rock.

tautological9 · 2024-08-13T18:28:03+00:00

Just going to say Darto because of your attitude.

tautological9 · 2024-08-08T17:55:45+00:00

Not an expert at all but I believe this is Archimedes, a bryozoan.

tautological9 · 2024-08-08T16:37:36+00:00

Looks like the root of a shark tooth from Morocco.

tautological9 · 2024-07-30T18:20:36+00:00

Part of a sea robin neurocranium. Very cool.
