This summer, news was published on facebook: the waves of the Baltic Sea washed up an unknown artifact between Klaipeda and Palanga:
This is some kind of metal, pressed, or poured into stone. Or vice versa, metal, poured with liquid stone.
There are holes on the back of the artifact and they also contain metal. Due to the lack of green patina, it is suspected that it could be gold. Or bronze without oxides, because covered with sand.
The appointment is difficult to judge. One can only draw some analogies with products from the time of our civilization. There is an assumption that this is part of the tube of the 76 mm shrapnel shell:

Kyshtym find
A piece of granite or diorite found in the vicinity of Kyshtym.
Parallel cuts were made on the surface of the stone by an unknown tool (presumably with a circular saw) with a cutting width of more than 1 cm. Currently, stone discs with such a disc width are not used even in stationary machines.
If you look closely, you can see grooves inside the slots. And the slots themselves are rounded.
Comment of the author who posted photos of this find:
The fact that sometime in the past there was a high level of stone processing, says this bridge:
Moreover, later it was "covered" with rubble stone, raising the ground level and leveling the area with its stone structure.
Similar blocks at the base of the old building
Another artifact in stone that makes you think:
Cogwheel in stone
The opinion expressed in the comments to the video is that it is pyritized ammonite.
A cut of such an ammonite from a rock with a metallic luster. It is possible that there is something similar in this pebble in the video. They really look like gears. It is possible that there is no puzzle in this example. But the findings at the beginning of the article need to be carefully researched.
Can you imagine how many similar things are in private collections or are simply lying on the shelves of ordinary people who find them?
