This Paddlefish is truly a remarkable specimen as it closely resembles the recently extinct (due to overfishing) Chinese paddlefish (Psephurus gladius) which fed on small fish and crustaceans

it took on the shape of the fibrous mineral

Picture Sandstone | Arizona Sierra star copper-laden mineralsArizona Sierra is found in Northern Arizona. The design patterns are natural. Its color is achieved by heat treating the stone. This causes the iron oxides found naturally in the stone to oxide, the richer the iron the deeper the color. Measures approx. 4. 25" x 4" x 0. 5" This is natural sandstone, formed 180 to 220 million years ago by wind and water as part of the geological formation "Shinarump." The colors and designs were induced by a mineral
