Natural Rock-Egg: Dragon Septarian Crystal Ball 47mm round 146 grams with stand
Septarian Concretion or Septarians were formed during the Cretaceous Period, about 50 to 70 million years ago. Sea levels were much higher then and the Gulf of Mexico reached inland to Southern Utah where many of the septarian nodules are found. They are also found in Madagascar where conditions were similar. Another humorous tag is “Petrified Mud”.
