coprolite

The word 'coprolite' is a modern scientific compound formed directly from Greek elements. The first part, kopros, has a straightforward ancient meaning of excrement or manure. The second part, lithos, is a common Greek noun for stone or rock. Combined in the early 19th century, the term was coined to provide a precise, descriptive label for the mineralized remains of animal waste discovered in geological strata. The logic is transparently literal: 'dung-stone,' a term that accurately reflects both the material's origin and its fossilized state, bridging ancient vocabulary with the needs of modern paleontology.

Structure: copro (dung) + lite (stone) - copro: From Greek kopros, meaning "dung, feces." It functions as the core semantic root. - lite: From Greek lithos, meaning "stone." It functions as a suffix indicating a mineral or fossil substance.
