What Is This?
Ed found this on the beach this week during a Thanksgiving walk (west-facing beach). You can see that there is a kind of groove in the center hole. The rock itself seems to be some kind of conglomerate or aggregate. It's pitted and has a slight metallic sheen. It is about 3 inches across and, as in the picture, mostly hexagonal.
A spindle whorl? A net anchor? Some kind of boat equipment? Help?
