Limestone has low porosity; it is weather resistant and has a density of between 2.5 and 2.7 kg/cm3. It has a hardness of between 3 and 4 on Moh’s Scale and a water absorption of less than 1 percent.Limestone is a sedimentary rock made almost entirely of fossils. Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.

Limestone is made up of fossils. After small marine animals die, their shells and skeletons build up on the ocean floor. Over time, the layers of fragments press down on each other, squeeze out the water, and recrystallize into solid rock. Sometimes the original shells, which are now fossils, are still visible.23 feb 2018 ... Find the limestone.
