Inorganic Limestone and Inorganic Gypsum
Limestone is a sedimentary rock made up mainly of the mineral calcite (calcium carbonate). It may be made up of biogenic calcite such as shells or inorganic calcite deposited as fine grained "micrite" although some micrite may also have a biological origin.

Animals don't have bones made from gypsum so all gypsum deposits have non-biological origin.
