Physical properties

Hardness varies from 3 to 5 on the Mohs scale depending on mineral replacement. Typically brown, gray, or black with a dull to earthy luster and amorphous crystal structure.

Formation & geological history

Formed through the rapid burial and fossilization of organic feces in sedimentary environments, replacing original matter with minerals like silica or apatite.

Uses & applications

Valued as a unique fossil specimen for scientific study and paleontological collections.

Geological facts

Coprolites provide crucial evidence about the diet, behavior, and ecosystem dynamics of ancient organisms, including dinosaurs.

Field identification & locations

Found embedded in sedimentary rock layers worldwide; identified by characteristic rounded, nodular shapes and inclusions of undigested bone or scales.
