What is this neat rock?

I found this dude when I was at the creek here in middle Tennessee a few years back. Is it simply a super cool, all natural rock formation, and if so is it a geode? Maybe a Native American game piece? A girl can dream! 😂Just need some other opinions, any feedback will be appreciated!

Either a fortified agate or fortified jasper. Can you take a pic of it outside in the sunlight?

Looks like a vertabre that broke and fossilized Or a fossilized wood piece.
