Septarian Nodules, often referred to Dragon Eggs, are fascinating geological formations known for their distinctive cracked patterns filled with contrasting minerals. Formed millions of years ago in sedimentary environments, these nodules developed as mud and clay concretions shrank and cracked during early stages of burial. Over time, the fractures filled with minerals such as calcite, aragonite, and limestone, creating the bold yellow, brown, and gray patterns seen when the nodules are cut or polished.
