Septarian

Named for its characteristic angular cavities or cracks (“septaria”), this stone dates to the Cretaceous period and is prevalent in southern Utah. Approximately 70 million years ago, volcanic eruptions created muddy nodules that were gradually filled with yellow calcite. The surrounding clay and mud eventually turned into dark brown aragonite and grey limestone. Barite, ranging from transparent to chalky white, is also present in septarian, which is also known as "dragon stone."
