Septarian Dragon Polished Nodule Halves
Septarian Dragon Polished Nodule Halves are also known as split septarian dragon eggs. About 50 to 70 million years ago, volcanic eruptions resulted in the formation of these septarian nodules. Dead sea life is chemically attracted to the sediment that surrounds it. Those two combined forms mud balls which, when the ocean recedes, dries up. Due to their bentonite content the mud balls also shrink in size. This creates cracks inside.
The exact mechanism for how the cracks form in the concretions is a mystery. One possible mechanism is the dehydration of the clay-rich core of a concretion causing it to shrink and crack. Another is the cracks being due to the expansion of gases produced by the decay of organic matter within a concretion. Earthquakes have also been a suggested as yet another mechanism. The mud balls also tend to crack in seven points in every direction. Thus creating the distinct pattern these nodules exhibit. This is where Septarian comes from, the Latin “septem” meaning seven.
Septarian specimens help in remaining firm in difficult situations without closing down. Septarian Nodules are speaking stones. They enhance communication on multiple levels.
These are natural specimens, so variations in pattern, shape, and coloration are to be expected. You will receive two halves that are similar to the reference specimens.
• You will receive two matching halves similar to the ones shown
• Each septarian dragon polished nodule half is approximately 2-3″ long and about 1″ thick
