Found on the beach in North Carolina

[RockHound022]

I found this rock with a shell imprint on the beach in North Carolina. I have searched around on the Internet but I’ve not been able to find anything quite like it. I find it interesting because it appears to not only be the imprint of a conical shell but a cross-section of the shell itself because of the sharp contrasted color and outlines. Although it appears black in the picture the rock is actually a deep brown color and was clearly once very jagged but has been smoothed. 
 

Any help identifying the rock and the shell would be appreciated. Thanks in advance.

This looks like a cross section of some type of high spired gastropod. Not sure of age or type of gastropod, as it could have come from off shore, or been washed into the ocean from inland. It also could have been transported offshore from ballast from old ships.

 

Very cool find, though.

Thanks for the info. Any idea if it might be anything of value?

We don't do valuation on the forum - so whatever it's worth to you is what it's worth! It's a very cool find, regardless of it's rarity!

A million thumbs up to this - every fossil is worthy of appreciation and glory!

 

Indeed it is a cross-section of a gastropod, and a really, REALLY crisp one at that, superb find - you can even see the shell preserved in the darker crystal.

Any idea how old or what era it might be dated?

Nice gastropod! I once thought I found one like this but it turned out to be a controidal fracture.

Conchoidal fracture ?

Sorry! I keep misspelling important words like conchoidal and apical.

Not possible with any certainty without knowing where it originated. This and similar species' existence spans hundreds of millions of years, so if we can't determine the strata it comes from we can't even begin to guess the age. They go back all the way to the late Cambrian.

Can you take pics of the "rock" from all angles? Also, which NC beach did this come from? That could help determine the age and possibly narrow down an I.D.
