Fossiliferous limestone is rich in visible fossils, such as shells, coral, and even ancient marine life remains. These fossils provide a window into past ecosystems, helping geologists understand historical climates and environments. The rock is typically formed in shallow marine waters where organisms thrived and were subsequently buried …

Brachiopod, trilobite, coral, ostracod and other invertebrate shell debris is present in many coquinas. The fossil debris of coquina is composed of calcium carbonate, making coquina a variety of limestone. Coquina contains very little silt or clay-size particles, and its fossil fragments are lightly cemented together.

It typically has very similar colors and textures compared to limestone, and forms in the same geological settings. Dolostone can be easily differentiated from limestone by using an acid test. While limestone will readily react and fizz to a 15% HCL solution, dolostone will only give a weak reaction after freshly scratching the surface with steel.
