Septarian Nodule, also referred to as Dragon Stone, The name comes from the word “Septaria”, which usually refers to any concretion with internal cavities or cracks. This unique mineral was formed around 50 to 70 million years ago during Earth’s Cretaceous Period. Sea life during that time became attracted to the molten sediment that was produced by these massive volcanic eruptions. Overtime as sea life began to die, their chemical composition became enriched in sedimentary rock, forming the nodules we see today.
