Their massive shells, composed of aragonite, exhibit distinct growth bands – annual, seasonal, and even daily – as well as subtle changes in elemental composition. These features enable a high-resolution chronicle of both clam growth and the changing marine environment.\u003c\/p\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"1176\" data-start=\"567\"\u003eSince their appearance on (sub)tropical reefs in the Middle Eocene, with Tridacna itself appearing in the Early Miocene, these clams preserve a long history of reef ecosystems. Unlike many other reef organisms, such as corals, their dense shells are largely resistant to diagenetic alterations, making them particularly reliable indicators of past environmental conditions. Their rapid growth – from millimeters to several centimeters per year – and lifespans often spanning several decades underscore their outstanding scientific importance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Urweltsteinbruch Holzmaden","offers":[{"title":"Default Title","offer_id":55857731240262,"sku":"F726","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/6131\/1302\/files\/fossilized-shell-sold.png?v=1778000146"}],"url":"https:\/\/www.urweltsteinbruch.de\/en\/collections\/sold-2026.oembed","provider":"Urweltsteinbruch Holzmaden ","version":"1.0","type":"link"}
