Its Japanese name, Akanishi, comes from the reddish interior of its shell aperture — a large, predatory sea snail commonly found in the tidal shallows of Japan's inland bays.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eA hundred and twenty thousand years ago, this was not yet land. It was a warm inland sea called the Ancient Tokyo Bay.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe rock snail once lived on tidal reefs, growing and clinging and dying with the rhythm of the tides. Its shell was buried in fine sand, settling into the uppermost layer of the Shimosa Group — the Kioroshi Formation. Groundwater carrying dissolved calcite seeped slowly into the seams of the shell, year after year, forging its once-fragile calcium carbonate structure into something nearly as hard as stone.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis is what makes the Kioroshi Shell Bed unique: its shell fossils, cemented by calcite, grew so hard that since the Kofun period, they were quarried and used as building stone for burial chamber walls. These were never just fossils. They were once the very stone that carried history.\u003c\/p\u003e","brand":"Taiwan Mineral Shop by The Brothers' Stones","offers":[{"title":"Default Title","offer_id":43486137679935,"sku":"FS005","price":12000.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/3779\/2575\/files\/FS005-02.jpg?v=1783086331","url":"https:\/\/mineral-taiwanshop.thebrothersstones.com\/en-asia\/products\/%e7%b4%85%e7%9a%ba%e5%b2%a9%e8%9e%ba%e5%8c%96%e7%9f%b3%e6%93%ba%e4%bb%b6-%e6%97%a5%e6%9c%ac","provider":"Taiwan Mineral Shop by The Brothers' Stones","version":"1.0","type":"link"}
