Dragon Egg Early Diagenetic Cretaceous Pyrite Nodule Concretion Mooreville Chalk

Dragon Egg Early Diagenetic Cretaceous Pyrite Nodule Concretion Mooreville Chalk. This is a natural cretaceous pyrite nodule concretion, often called a "dragon egg" formed roughly 90 million years ago in the Mooreville chalk formation of Alabama. These early diagenetic pyrite nodules developed deep in ancient marine sediment when iron and sulfur reacted around organic material, slowly creating dense metallic spheres as the chalk layers hardened over time. This specimen is completely natural and unaltered, showing the authentic shape, weight, and surface texture that makes Mooreville Chalk Pyrite nodules Rare, highly sought after by mineral and fossil collectors. This is a excellent collector grade example for any one interested in Natural earth formed specimens. Framed and ready for display, comes with frame and shows off its great unique colors. Don't Miss out on this cool fossil of history. Size Length 2.5 in With 1.5 in Thick 1 in
