Biological (vertebra piece maybe?) or just a rock?

Found on Myrtle Beach.

No idea what it is or whether it's worth keeping! Ideas?

I think it is just a rock.

No such thing as "just a rock".

It looks like a piece of a phosphate nodule.

Not a fossil.

Agree with phosphate nodule.

Those things the frost lifts in the dirt roads I maintain. Just rocks.
