Ammonite

This block of oolitic limestone also contains belemnites and pecten shells (scallops). The name oolite refers to the tiny egg-like structures that make up the rock. These are grains of sand or shell fragments that were rolled around in a warm sea gathering layer upon layer of calcium. The name oolite is derived from the Greek for eggs.
