Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis. Limestone also forms as a deposit in caves from the precipitation of calcium carbonate.

— We found that eggshell calcium carbonate content decreases as species' residual body mass (body mass relative to egg mass) increases. As such, species with eggs that are small relative to the size of the incubating parent have a lower calcium carbonate content in their eggshells, which would suggest that the shell's ability to support the mass ...

The two most common types of calcium supplements are in the form of calcium carbonate and calcium citrate. The carbonate form needs to be broken down by stomach acid before it can be absorbed, so it is usually taken with food; the citrate form does not require stomach acid and can be taken without food.
