Septarian dragon eggs are Septarian nodules that have been carved and polished into a egg shape. The natural, cracked pattern of the septarian gives the surface of these polished stones a "dragon skin" look, hence the popular name. Septarian geodes are a specific geological formation, that occur when minerals (primarily calcite and aragonite) fill in cracks in a concretion. This creates a very unique patterning and often leaves hollow spaces inside, forming the geode.
This Septarian dragon egg geode is from Madgascar and was formed during the Jurassic period, around 160 million years ago.
