caption_attribution_description: English: Sample of Fossiliferous Limestone
context_page_description: Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces. The fossils in these rocks may be of macroscopic or microscopic size. The sort of macroscopic fossils often include crinoid stems, brachiopods, gastropods, and other hard shelled mollusk remains.
  In some cases, microfossils such as siliceous diatom shells in deposition may convert over time to opal and chert, providing the only inferred evidence of bioactivity preserved in limestone.
  Fossiliferous limestone is termed biosparite limestone under the Folk classification of sedimentary rocks.
  Lagerstätte are a class of fossil bearing rocks that includes fossiliferous limestone.
