About 60% of fossil shells fluoresce. This was a quick set-up using a cardboard box and an ultraviolet LDE flashlight. Flashlights like this are long wave, so they don't work with nearly as many species as shortwave, but for some species it doesn't really matter which wavelength one uses. The $15 flash light was much more expendable than my shortwave light!
