Septarian (aka Septerye or Dragonstone)
Septarian is a very unique stone found in only a few places on earth. In the USA Septarians are found near Zion
National Park in Southern Utah. They are also found in Mahajanga in Madagascar and Morocco.
They were formed in an ancient sea floors during the Cretaceous Period (50-70 million years ago). As they
weathered out of the gray or tan clay hills, one at a time, they could be picked up on the surface. Now bulldozers
are required for their excavation, usually 20-30 feet underground. Septarian nodules are unusual to look at and
can vary considerably in color and shape.

In contrast to most geodes, which are volcanic in nature,   Septarians are a form of sedimentary geode. They
formed on sea beds millions of years ago and, when they dried out, they cracked and formed hollow interiors. The
interiors usually become either partly or completely full with other minerals, such as calcite, giving Septarian its
unusual texture and features. Volcanic eruptions killed the sea life and they became  trapped in the sediment and
formed mud balls, the ocean receded and the balls were left to dry and crack. The ocean returned depositing
more shell life above them. As this decomposed, calcite from shells was carried down into the cracks of the mud
balls, calcite crystals formed. A thin wall of calcite was transformed into Aragonite dividing the Bentonite clay
(shale) exteriors from the calcite centers. Because of this dividing wall (septum in Latin) the geodes are called
Septarians.

Yellow centers - Calcite                    Brown lines - Aragonite
Gray rock - Bentonite                     White or clear – Barite

Septarian is also known as 'Dragon Stone' Its name 'Dragon Stone' comes from an old Malagasy legend.
It is said that when the 'Dragons' died out they fossilized & became part of the sea bed that later became
Septereye/Septarian & it is this formation that resembles the 'Scales of Dragons' !!
Septarian concretions or Septarian nodules, are concretions containing angular cavities or cracks, which are
called "septaria". The word comes from the Latin word septum; "partion", and refers to the cracks/separations in
this kind of rock. One occasionally finds the erroneous explanation that it comes from the Latin word for "seven",
septem, referring to the number of cracks that commonly occur, but this is incorrect. Septarians may have
openings called Vugs ranging in size from large to small, large being cavernous and small being pencil tip size.
