Septarian is an ancient healing stone, sometimes called a Dragon Stone because its formations can resemble the scales of a dragon. It’s nodules were formed during the Cretaceous Period, around 50 to 70 million years ago. At that time sea levels were much higher and the Gulf of Mexico reached inland to southern Utah where many Septaria nodules are found. They are also found in Madagascar where conditions were similar.
Periodic volcanic eruptions killed the smaller sea life which sank to the sea bed and started decomposing. The minerals in the shells and carcasses attracted sea floor sediments which accumulated around the carcasses and formed nodules or mud balls. When the ocean eventually receded, the mud balls dried out and began to shrink and crack into the beautiful patterns that we see inside Septaria nodules.
The name Septarian comes from the Latin word “septum” meaning seven, or “saeptum” which means a wall or enclosure. As the balls dried they shrank inside and had a tendency to create a distinctive pattern of 7 points in every direction.
