this is how I store extra/bulk fossils. Each shoe box sized container is a site and age. The best specimens of an age are in the 30-40 space plastic fishing boxes, The one cabinet with glass is 6' wide x 5' high. The other storage shelves are 4' wide x 5' high. You can but the storage shelves for about $30 each and the plastic shoe boxes for a $1. The multi-storage boxes are about $4.
