This specimen is a polished 4.504" piece of agatized coprolite or "dinosaur dung" from the Morrison Formation in Utah. It is attributed to a 150,000,000-year-old sauropod, a long-necked herbivorous dinosaur. A small information card is also enclosed, which also serves as the certificate of authenticity.

Please Note: The specimens vary in size, shape, and color. Each is completely unique!
