How does fossil containing limestone form
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.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.

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.Geology. Limestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments. Limestone, a sedimentary rock, is made up mainly of calcite, which is made up mainly of the skeletons of microsopic organisms.Fossiliferous limestone, a common subtype, contains visible fossils embedded in its structure, providing valuable insight into past marine ecosystems.
