fossil rich limestone is made by the earth and is enhance with fossils although the chemical is man made, the two are basically the same.

Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P

a soil rich in lime on top of a limestone bedrock
Carbon rich coke limestone and iron
Acid rain dissolves the carbonate rock-limestone causing rich patterns on it. limestone gets naturally sculpted through these acid rains. They also form hanging stalactites, stalagmites, etc. They create rich landscapes.
They are all sedimentary rocks. Limestone is formed from calcium-rich sediments, such as deposits of deceased shellfish, shale forms from clay and/or silt and sandstone forms from sand.

Caves are generally formed in areas rich in limestone, which erodes as water flows over it over time.
Rocks that are rich in the mineral Calcite, such as limestone, are especially vulnerable to chemical weathering.
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
