I store by type first so one cabinet for ammonites, one for other mollusca, one for plants, one for echinoderms etc... Then within the ammonite cabinet by age and location. So all Liassic Yorkshire ammonites would be together. this is because I have quite a large collection from many different locations. A friend of mine has collected from far fewer sites but has more fossils from each, therefore he stores by location first. it all depends on how your collection is made up which way is best.
