Is this a ray barb fragment?

[Spooky24]

Is this fossil from the Calvert Cliffs a ray barb fragment, or something else entirely?
It measures 1/3 of an inch as far as it's size goes.

Thanks for any suggestions regarding it's identity.

It is part of a ray tooth.

It is ,I do believe, from a ray.  In this case it is a ray tooth, part of the crushing teeth plate of a stingray.

 

I see @Darktooth was one "click" ahead of me in replying.

Thank you both for helping me identify it.

It's part of a ray plate (their 'teeth' that they use to crush their food). A barb is the 'stinger' that is found inside their tails. Happy hunting!
