This substantial 16.16-pound Septarian Egg, measuring 8.75 inches tall and 6.4 inches in diameter, showcases the unique geological formation of septarian nodules. Originating from sedimentary rocks in regions like Utah, Madagascar, or Morocco, these spheres are composed of calcite, aragonite, and limestone. Their characteristic cracked patterns result from mineral deposits filling the natural shrinkage cracks formed as ancient mud balls dried. Ideal for collectors and geology enthusiasts, this specimen offers a tangible connection to ancient sea floors and sedimentary processes.
