Description
Among the most distinctive specimens from the new find are mineralized arthropod burrows and helical burrows occasionally found in the Miocene sediments of southern Maryland. This is a particularly dramatic piece with a mineralized cluster atop the end of the spiral burrow. Chesapeake biominerals, including Hollandite, Todorokite, Romanechite, Birnessite, and other unusual manganese and iron species, form when metal-rich subsurface waters emerge from the face of the cliffs along the western shore of Chesapeake Bay. Microbes exploit the chemical richness of the waters by oxidizing the metals and precipitating minerals in beautifully sculpted masses. The resulting specimens containing mixed amounts of these related species, such as those you see here, are among the finest examples of their style anywhere in the world and are unique in their aesthetic appeal and scientific interest. A portion of all sales goes to support the study of Chesapeake Bay geology through the laboratory of Dr. Robert Hazen.

How this data is collected: Our system continuously monitors mineral listings from authorized dealer partners across the internet. We have explicit permission from all dealers whose listings we track - any dealers who have not provided specific and explicit authorization are NOT listed and NOT tracked by our system. When a previously available listing is marked as sold or removed from sale, we record this as a completed transaction. While we cannot guarantee the exact final sale price (as negotiations may occur), this data represents publicly listed prices for specimens that have transitioned from "for sale" to "sold" status. This provides valuable market insights based on observable listing behavior patterns.
