Limestone that contains an abundance of visible fossils is termed:

A. travertine
B. evaporitic limestone
C. fossiliferous limestone
D. biochemical chert

Answer :

Final answer:

Limestone with an abundance of visible fossils is known as fossiliferous limestone, which forms in marine environments rich in biological materials. This type is distinct from other limestone types like travertine and evaporitic limestone. Recognizable fossils often include shells, coral, and other remains.


Explanation:

Limestone with Fossils

Limestone that contains an abundance of visible fossils is specifically classified as fossiliferous limestone. This type of limestone is formed from the accumulation of shells, coral, and other fossilized remains, often found in marine environments.

Unlike other types of limestone, such as travertine, which forms from mineral deposits in hot springs, or evaporitic limestone, which is created from the evaporation of water, fossiliferous limestone is characterized by its rich fossil content. Additionally, biochemical chert is a different sedimentary rock that is not directly related to limestone and primarily comprises microfossils.

Examples

  • Fossilized shells of mollusks.
  • Coral fragments from ancient reef systems.
  • Trace fossils from organisms that lived in limestone environments.
