Gypsum. Gypsum forms deep under water when creatures like clams, oysters, scallops and other shellfish die. Their remains settle to the ocean floor in layers. Over time, hundreds of layers form and push down from on top of the original layer. This causes it to be turned into rock. Some of this rock contains gypsum.
