Originally formed in an ancient sea floor some 50-70 million years ago, sediment collected around sea life as they decomposed, forming a concretion. Calcium carbonate from the shells of these creatures began to take a new form over time, creating calcite crystals and bands of aragonite. As the oceans receded, these mud balls hardened, shrinking and cracking in the sun. The gold-colored crystals inside are the calcite, the brown is aragonite, and the outer surface is composed of limestone.\u003c\/p\u003e","brand":"DavesRockShop","offers":[{"title":"Default Title","offer_id":46038516170831,"sku":"i-bk-432","price":445.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/5568\/9807\/files\/IMG_6939.jpg?v=1783717340","url":"https:\/\/davesrockshop.com\/products\/11-1-2-utah-septarian-bookends","provider":"Daves Rock Shop","version":"1.0","type":"link"}
