Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water. Table of Contents What Is Limestone? Biological Limestones Chemical LimestonesAnother issue is that the “dolomitization” process — limestone becoming dolostone — causes fossils to lose a lot of their detail.

Ammonite Fossil CharacteristicsLimestone is made up of fossils. After small marine animals die, their shells and skeletons build up on the ocean floor. Over time, the layers of fragments press down on each other, squeeze out the water, and recrystallize into solid rock. Sometimes the original shells, which are now fossils, are still visible.Most of the fossils I hunt are either in chalk (soft limestone), limestone, or a chalk/calcite combination.
