Polished fossilized mollusk

I found this today with two points. I've seen plenty of fossilized shells, but never one polished to this extent. Does anyone have any experience with these?

May have been used to burnish pottery pre-firing?

Possibly, but this site is pre-pottery.
I'm thinking trinket or 'worry" stone.
