| creatures of the open tropical seas, ammonites are abundant in limestones from tropical reefs. the characteristic spiral was formed by partitions or chambers of the coiled shell where the ammonite lived. once the ammonite grew too large for its living chamber, it formed a new one and moved into it. the empty chambers filled with gas to assist buoyancy at different depths in the oceans. |

| after a 330 million year survival on earth, ammonites became extinct at the end of the cretaceous period, some 65 million years ago. |
