I found this in my back yard on the Eastern End of Long Island in NY.

Can anyone tell me what it might be?

I dont know, thats a tough one to tell. It looks pretty well rounded and like there could be some wear. Maybe an arrow shaft straightener? But if it were, it would be a perfectly consistent groove all the way across. You could try putting a pencil or something through it, to see if its perfectly smooth from end to end. If its not, its probably nothing.

Rocks come in so many shapes and sizes even if it was a tool you would never know on a rock like that. Cool find though!!!!

It has the look of something I have seen before some kind of clay concretion I can't remember the correct name of it

Banded rock with thin, weak layers between thicker, stronger ones.
As this rock has aged, the weak layers break down.
The cleavage, as seen, follows the bend of the weak layers.

The inside curve is one of these weak points that has shed smaller versions,
The outside curve was actually the inside curve of the larger piece from which this one was shed.

This rock didn't need man to become like this.
It naturally breaks down into smaller versions of itself.
That's how this rock rolls.

Thank you! That's very interesting.
