From the Greek word” Kopros” and “Lithos” means dung and stone: petrified feces ( animal waste). In this case is unidentified dinosaur coprolite. These unusual materials are found in exposed sedimentary rocks and fossilized like other animals remains. This piece is from North America, probably Utah, but I am not sure, and belong to the Jurassic period. I uncommon to find good colorful pieces, while most of them are grey-brownish, and even more rare is to find perfect agatized areas with fortification bands.
