Septarians Nodule

Septarians NoduleРwere formed during the Cretaceous Period, Age of Dinosaurs

Septarian Nodule are concretions containing angular cavities or cracks, which are called “septaria”.

Septaria Meaning noun- a concretionary nodule, typically of ironstone, having radial cracks filled with calcite or another mineral.

Septarian Nodule were formed- Cretaceous Period.–This is when land was covered by water, 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 you see inside the septarian nodules today.
