Turritella agate is a stone which contains spiral fossils of the gastropod, Elimia tenera; extinct, freshwater gastropods, frequently mistaken for turritella, a modern variety of sea snail. E. tenera disappeared during the Eocene period and may be found today only as fossils, preserved in southern Wyoming's Green River formation, as well as throughout regions of northern Colorado and northeastern Utah. The beds from which this fossil originates, date to approximately 50 million years. Pendant Dimensions are 43x23x8mm (1.7" x 0.9" x 0.3") and the earrings are 47mm (1.9") long (total length from piercing to base). *Ships with insurance and international tracking.
