Whatzit

Found this in my yard, which is covered in gravel, at least as much as I can afford.  I hate mowing.  The material is probably Paleozoic, but could be up through the Pleistocene.  It is flat on both sides.  Initially thought coral, but doesn't look right.

Zit looks like the top of a Rugose Coral.

Caldigger is right.

Thanks, I guess I have never looked at a horn coral in this orientation.
