Septarians were formed during the Cretaceous period about 65 million years ago. Decomposing sealife killed by volcanic eruptions had a chemical attraction for the sediment around them, forming mud balls. As the ocean receded, the balls were left to dry and crack. Decomposing calcite from sea-shells was carried down into the cracks in the balls forming calcite crystals. These are the dark brown crystals lining the cavity - here they are Aragonite, a form of calcite. The name is derived from the Latin septem, meaning seven, as the mud balls crack with seven points in every direction creating the beautiful design.
The passage describes the formation process of septarian nodules, including the time period, the role of volcanic eruptions, and the chemical processes involved. It also explains the origin of the name "septarian."
