Fossils in limestone.

Fossil Geology. Fossils are found primarily in 3 types of sedimentary rock- shale, limestone, and sandstone. Shale is either mudstone or a mixture of ancient mud and clay found at the bottom of calm bodies of water like lakes, swamps, and shallow seas like the Western Interior Seaway. The shale splits easily into layers and within these layers ...Yes, limestone fossils can be heavily detailed. Limestone forms from the accumulation of marine sediments, and often preserves fossils with intricate details. The preservation of soft tissue structures like feathers, skin, or delicate structures such as plant leaves or delicate shells is common in limestone.Sedimentary rock - Limestone Formation, Calcium Carbonate, Fossils: Limestones originate mainly through the lithification of loose carbonate sediments. Modern carbonate sediments are generated in a variety of environments: continental, marine, and transitional, but most are marine.Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO 3) in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces.
