Septarian Nodules were formed during the Cretaceous period, 50 to 70 million years ago. Decomposing sea life killed by volcanic eruptions, had a chemical attraction for the sediment around them, forming mud balls as the ocean receded, the balls were left to dry and crack.
Because of their Bentonite content, they also shrank at the same time trapping the cracks inside. As decomposed calcite from the shells was carried down into the cracks in the mud balls, calcite crystals formed. A thin wall of calcite transformed into aragonite separating the bentonite heavy clay exteriors from the calcite centers. Because of this, the nodules are called Septarians.
Septarian concretions or septarian nodules, are concretions containing angular cavities or cracks, which are called "septaria". The word comes from the Latin word septum; "partition", and refers to the cracks/separations in this kind of rock Septarians are composed of Calcite (The Yellow Centers), Aragonite (The Brown Lines) and the Outer Grey Rock is Limestone. Occasionally the fossil or some of the fossils, which started the formation of the rock, can be seen in the rock.
