Come on guys, seriously? I honestly thought it was an indian tool of some kind. I’ve never seen that kind of hole in flint rocks. Ever.
I think it was likly worn around the neck with a corded Buffalo skin. If you had one the women would know you could start a fire. Where did you find it?
Holes do occur in flint/chert, as do blastoids and other fossils of many kinds, even crystals. Sometimes fossils that have fallen out or dissolved away, or trapped liquids or gasses or debris during formation, are responsible for the holes.
