That's very interesting! :)
Maybe a coral fragment ?

It looks to me more like calcium that chiton...
Maybe urchin 'teeth'?

Wow...those are really cool looking! Although, I think this is a little beefier. Somewhere in a box, I have some dried urchins that my grandmother collected years ago up in Alaska. I might have to dig them out to see if they still have their mouth parts. :)

There appears to be an endless variety of form with these things. The image I posted was just the first one I came to.

Could also be way off base...

You could be correct...this is way, way out of my knowledge base. The whole internal structure (Aristotle's lantern) is quite beautiful!

The glossy appearance makes me think enamel. Looks like part of an alligator gar scale.

Enamel would fit with what I'm seeing. However, I don't think this is a fragment, since it not appear to be broken (except perhaps in one chipped spot at the narrow end). Aren't scales usually smooth on the under side? Or would the bumpy side be on the surface? With the little nodules on the bottom/sides, it almost appears like it would have been embedded in the skin. What about a denticle/dermal plate? Do gars have those as well? Or am I talking apples and apples? Would additional (better) photos of the sides help? Sorry, I feel like a toddler with all the questions - just way out of my element.

Everyone is proposing totally different things! This one sure seems like a tough one... 

I'll be following the topic, as I am curious of the evolution on the ID suggestions. :popcorn:

 

Whatever it is, it sure does look cool, so nice find Lori!

It might be also a dermal denticle fragment.

The bumps on the underside don't seem right for a gar scale. 

I think the bone has decomposed leaving only the enamel part of the scale.
