Limestone fossil can be found in the Indian Ocean.
Limestone is biological sedimentary rock made up of the skeletons and fecal debris of dead creatures. According to the New Zealand government’s website, limestone consists almost entirely of fossils. Limestone usually forms in oceans and seas within 30 degrees of the equator. Limestone fossil is easier to mine than many other rocks and has a range of uses.
Building and Roofing
Fossil limestone can be shaped into blocks and used in the construction of buildings. It is often used for stone facings and to create floor tiles. Fossil limestone also makes effective stair treads and window sills.
Fossil limestone that is crushed down into granules can be used for asphalt shingles and roofing. Limestone granules make an effective coating that is resistant to both weather damage and heat, as stated on the Geology information website. Fossil limestone can also be used to construct top coats on roofing.
Rock dust, also referred to as mine safety dust, is made from crushed limestone granules. It has a white powdery appearance and is sprayed onto surfaces in coal mines to improve visibility for workers. Rock dust inhibits the level of coal dust raised by mining activities, helping workers to breathe more easily. It also reduces the risk of explosions from the volatile coal dust particles.
Fossil limestone contains high levels of calcium carbonate, which can be used as a strengthening food for chickens. Chickens require calcium carbonate to yield strong eggs. According to the Geology information website, crushed calcium carbonate from limestone fossils is often fed to chickens as dietary supplements. Calcium carbonate can also be fed to dairy cows, which lose substantial levels of calcium when milked.
Fossil limestone has excellent acid-neutralizing properties, due to the presence of calcium carbonate. Crushed into tiny particles, it is used extensively on farms to treat soil with high levels of acidity. Lime fossil heated in a kiln produces carbon dioxide gas and calcium oxide. Calcium oxide is also used as a soil treatment.
