Ammonite shells are made of the calcium carbonate mineral aragonite. Over a long period of time, the aragonite can change into a more stable mineral form of calcium carbonate, called calcite.  

Over time the chambers of the buried ammonite shell can fill with mineral deposits. This produces detailed fossils and some shells can remain intact. In other cases, the shell dissolves and mineral deposits fill the cavity to produce a cast.
