Very unusual object

[Moe (fl)]

This rock was found almost 30 years ago along the Pacific Coast.

The ring is a little magnetic. My detector rings as iron. It is 3" x 3.5" inches and about 1" inch thick. The edges are smoothed out probably from being in ocean.

Any clues as to what this may be?

Thanks.

A piece of wire mesh (for strengthening) in a piece of concrete? Best I can come up with....

That makes sense. A chunk off some long-gone sea wall.

maybe the fossil of a robot star fish from a far away planet that crashed here thousands of years ago.

On one shot the round thingy looks hollow. They MIGHT be petrified eggs of some sort.

That's about all I can think of.
It might also be that the mesh has rusted away and left behind some rust.

If this was found anywhere along the coast from Orange County to as far north as Ventura and Santa Barbara (or on the Channel islands), you might research what are called 'Cog Stones'.

Cog Stones were used by the coastal native tribes, most likely, for religious purposes.

It looks as if a rusted, perforated, round, staggered steel mesh something like this was next to it; but with larger holes.

Thanks for all the replies!

I was thinking that this could be some kind of symbol, but the wire mesh suggestion makes sense. The diameter of the circle is 1 1/2 inch.

looks like chicken wire wrapping to me. Why anyone would wrap a rock in chicken wire is a whole new question.

... but did'nt they look more like "cogs? Round & toothed gear looking things?

I'm with BIGCY as being a round hole mesh wire.

Has the "rock" material been determined?

If it's concrete it would have to have been poured flat. So is the back flat? Perhaps the mesh was embedded for decorative look, like for a pool deck or counter top.

If it's a real Rock then it came from the sky.

Thanks for the replies.

The back side of the rock is flat. Its edges are roundish. The metal looking mesh is only on one side (imbedded in surface) but very worn off. The material of the rock is almost like pumice stone.

The diameter of the metal circle is 1 1/2 inch. Only a few of the darker spots are magnetic so I don't know if the metal has worn off.

I bought a new filter for my air conditioner today. As soon as I saw it I thought of your photo. The solid round thing is a quarter. I didn't spend much time focusing :>)

In the parks around my home in Michigan that have a stream or river that is washing the shorline banks away, the counties are encapsulating broken concrete and or smaller rocks in chicken wire cages. It stops the rivers when they are in flood stages, from washing the rocks and shorline banks away. Maybe some county or Army Corps of engineers were doing the same thing in the area where you were hunting. Could also be part of an underwater artificial reef.
