I found slabs of these kind in my garage. We have actually built a fence with these. They come from the factory my dad used to run here in Georgia (Caucasus). As I remember they call it a Uzbekistany shell stone. Any idea what are these? how old?
Thanks a lot.
The shells are bivalves, of which there are many types. I can't see enough detail on any one to help with ID.
The shell stone from Uzbekistan may not be the same age as this one from Georgia; the type of environment that results in such shelly sediments is fairly common.
Bivalves have existed over many millions of years, and unless we know exactly where the stones came from, it will be difficult to estimate their age (but somewhere between 5 and 500 million years).
In western Ireland, and in Caithness (Scotland), I have seen fossiliferous flagstones used (on-end) as walling.
Thanks a lot Mike.
