Septarian Nodules are small, rounded stones that have a smooth surface. They are typically about the size of a golf ball or a tennis ball. Septarian Concretions are larger stones that can be up to several feet in diameter. They often have a pitted surface, as a result of the shells and bones that have decomposed to form them.

Septarian concretions or septarian nodules are sometimes called Dragon Eggs. They form primarily in an ocean setting just below the sediment surface through a series of steps. Some sort of nucleus, such as a fossil, is buried in the sediment. Fine grained calcite mud precipitates around this nucleus and a hard mud ball is formed. The longer the ocean …
