A fossil or living foraminiferan of the Nummulites genus (or a related genus) that has a disc-like, spiral, calcareous skeleton. Fossil nummulites range up to several inches in size, making them quite impressive protozoa (single-celled, eukaryotic organisms). Nummulite fossils are common in Tertiary rocks, particularly in the Mediterranean area.Some calcite is also possible as a remnant of the dolomite’s precursor, limestone. Fossils are common in dolomite, especially sea shells and coral. Dolomite is, by definition, mostly made up of calcium-magnesium carbonate. If calcite is still the dominant mineral in the carbonate rock then it would still be classified as limestone or dolomitic limestone. This …
