Chert is micro- or cryptocrystalline silica (SiO₂; also known as chalcedony or flint) which forms under particular chemical conditions inside soft sediments. Like concretions, they form inside soft sediments, and when they weather out, their shapes can frequently look like fossils. (Chert itself can sometimes contain well-preserved microfossils.)

Limestone, or its metamorphic cousin, marble, is rock made primarily of calcium carbonate. These rock types are often formed from the bodies of marine plants and animals, and their shells and skeletons can be preserved as fossils. Carbon locked up in limestone can be stored for millions—or even hundreds of millions—of years.Fossils are often said to take a million years to form. However, as of 2014 it has been proven that a fossil can take a shorter period of time to form. This period can be a thousand years or less.Trace fossils represent the presence or behavior of ancient life, without body parts being present. Footprints, worm burrows, and insect nests are examples of trace fossils. Sedimentary rock contains fossils because it was built up layer upon layer, often trapping and preserving animals, plants, footprints, and more within the layers of sediment.Aug 10, 2023 · Limestone is not a fossil fuel because it is not made from the carbon-containing soft tissues of long dead plants and animals. It is formed by fossils based on animal shells. Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils. As the layers of sediment build up on top of one another, they create a physical timeline. The oldest layers, along with the organisms that were fossilized as they formed, are deepest. The youngest layers are found at the top. Dolomite, also known as " dolostone " and " dolomite rock ," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar ... The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides.
