These mud balls are then buried beneath additional layers of sediment and, as they dry, they start to develop cracks. Over time, minerals from the surrounding environment, such as calcite and aragonite, seep into the cracks and solidify. This process results in unique patterns within each nodule, giving them their distinctive look. What makes this process even more intriguing is that the outer layer of the nodule, typically composed of limestone or mudstone, hardens more quickly than the interior. This disparity in hardening creates pressure, leading to further cracking and providing more spaces for minerals to fill. Eventually, these minerals crystallize and bond, transforming the once-soft mud ball into a solid, strikingly patterned nodule.General Information Item(s) are shown with a ruler or coin for easy size reference.
