Definition

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

Formation

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
