- Septarian Heart
- 3.5 inch x 3 inch
Septarian (also called Dragon Stone) is formed as a result of volcanic eruptions and attracted dead sea life chemically bonding them to the sediment and forming mud balls. They are composed of Calcite, which makes up the yellow centers and Aragonite which are the brown lines. The outer grey rock is Limestone.
The name Septarian comes from the Latin word "septum" meaning seven, or “saeptum” which means a wall or enclosure.
