Think it might be an echinoid but not sure.

Cool find!

Thank you!
It's something similar, but I don't think it is echinoid. Shape is different.

No idea but I don’t think echinoid not that I’m an echinoid collector.

Steinkern from a brachiopod.

or maybe a bivalve ?

Brachiopod; the individual valves are left-right symmetrical, and different from each other.

Between this site and searching for bearings to fit a horse drawn (originally) sickle mower my spacial recognition neurons have about had it.

well... only if you think we might be right.  For my part, I would bet on educated guess rather than right.

It's totally different from Brachiopod.

Are you comparing it to images of the shell ?

Steinkerns are a cast of the inside of the shell.

I understand that. But no one brachiopod Steinkern have a middle line. they have look a like side lines, but not a middle line.

They all have a line. It's where the two valves meet.

A line shaped like this I have to admit is a better question though.

I don't think it's a brachiopod.

Fish bit seems more likely to me.

If this was a steinkern the inner infill material would be uniform with the external material.

Not if the inside was filled with soluble or otherwise mobile material after the initial burial.

Was it a surface find?
How large is the specimen?
Does it float in saltwater?
Does react to HCl or vinegar?
Were there other fossil in the same location?
Try to determine its hardness.
