Hi Eleanor sorry for the delay in getting to this. I hope that the attached file (Date.doc) will help out, after collecting the fossil and cleaning them I then but the info that is in this file on all of the fossil and also have the site listed in a catalog with all of the info about site location and its #. If you need more info on the way I do this you can call me at 252-756-8039 or e-mail me at [email protected]. I have around 15,000 fossils that I have collected and yes the info is on them all. This is just one of the many ways to curate & catalog and it works for me.George
