This is full of crystals. Crinoid? Belemnite?

In flint rock, shape is approx 10cm across.

Jurassic Coast, UK.

Thank you.

Hi, what i see isn't a belemnite. I don't think it's a crinoid either. It rather has a geologic look.

Can you tell us what what make you think it could be a crinoid or a belemnite ? And could show us photos of the other parts of the stone ?

Flint rock? Isn’t it less likely to encounter fossils in flint?

It's less likely but they do exist.

I do have fossils in flint, some are amazing.

It would stand to reason that, if fossils are less likely to occur in flint, then wouldn’t that make it more likely that your specimen is geologic in origin rather than a fossil? Just because you have fossils in flint doesn’t mean that every fossil-like structure is actually a fossil. Although, I could be incorrect in that fossils are less likely to occur in flint. Or I might just be using older data. Could someone else confirm the likelihood for fossils to occur in flint? Honestly, I’d like to know myself. And if you don’t get an ID from this forum, I’d suggest going to mindat.org and asking around there. Mindat is more geologically-oriented and you’d probably find someone with a different background.

Maybe try and look at other fossil examples that were found in the same area and see if any match. You could use Google images or photos from the Reference Museum here on the forum.

Somehow the specimen in question reminds me of trace fossils, maybe something in the line of radial to rosette-shaped ichnogenera like Arenituba, Dactylophycus, Gyrophyllites, Phoebichnus, Volkichnium, Asterichnus, Cladichnus, Dactyloidites, Asterosoma for example.

I think you are mistaken , i'm not the author of that post.

I said upwards that i thought it was geologic.

Here is an example of fossil in flint. The most numerous ones are sponges but you can find bivalves, urchins, foraminifers. Plants like this one are rarest.

An acquaintance found this on a ranch outside of Roscoe, TX. I presume it's some sort of fern. Any chance we could narrow it down further?

It's a lovely specimen with a special remembrance for the collector. Appreciate any help you can offer.
