Septarian concretion.

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 level stays relatively constant, the bigger ... Septarian concretion were formed during the cretaceous period, around 50 to 70 million years ago. Sea levels were much higher then and the gulf of Mexico reached inland to Southern Utah where many of the stones are found. They are also found in Madagascar where conditions were similar. Periodic volcanic eruptions killed the smaller sea life ...A septarian concretion is a type of concretion that contains angular cracks called "septaria." These cracks vary in shape, volume, and shrinkage. It is unclear what creates the septaria, but several mechanisms have been proposed, including the expansion of gases produced by decaying organic matter.
