Septarian or septal nodules are concretions containing angular cavities or fissures, called "septarium" that have become filled with calcite and aragonite. A concretion is a hard, compact mass of rock that often forms around decaying organic matter. In the case of septal nodules, the concretions formed in a decaying marine environment.

The cracks in the concretions are then filled in with minerals such as calcite (yellow) and aragonite (brown) and sometimes pyrite causing very interesting patterns, which have often been described as dragon skin. This is why this stone is called "the stone of the dragon" "Septarian dragon egg".
