it has been inlayed into a more robust matrix from the sandwich layers

Such stones are known as banded agate

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

fossil occurrences of Mioplosus are typically isolated rather than in mass mortality layers

Picture Sandstone | Arizona Sierra star it has been inlayed intoArizona 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
