On my last trip a couple of months back one of the people I talked to told me the fossils from one area are fluorescent.
So when I got home I purchased a light bulb and then a UV torch and started looking at some specimens.
The torch worked better and sure enough some specimens gave off orange, yellow and green.
Most specimens gave orange, particularly where crystals were evident in ammonites.
I could not get a decent photograph myself but a friend experimented with one piece and the end photograph shows the actual colour seen.
Next trip I will try a night fossick. below is a section of wood that has been mostly replaced with crystal.
Does any one else have fluorescent fossils?
