4 years, 10 months ago4 years, 10 months agoAnyone on here ever see this video? https://www.youtube.com/watch?v=T_HqYfzIHVo&feature=youtu.be The fellow is collecting fossil shells in Florida at night using UV flashlights. He finds a lot of cone shells with color preservation that only shows with the UV light. Anyone know the age of these fossils or where he might be collecting?

I can’t open the link, but I believe it’s the video by PaleoCris? I saw it too, absolutely crazy. I believe Cris mostly hunts in the Nashua Formation (Pliocene) when it comes to shells, but I’m not too sure if this location is also from that formation.
Max, yes it is paleochris. I don’t know why the link didn’t work so here’s another: https://www.youtube.com/watch?v=T_HqYfzIHVo . So whereabouts in Florida is the Nashua Formation?
Thanks for sharing this video Jack!
Sure! This is the first time I have seen color patterns show up with UV but these are fairly recent fossils – Pliocene I believe. I have gone somewhat nuts on fluorescent minerals and stumbled on this on one of the sites I check for that phenomena. Many of our fossils have some degree of fluorescence – usually the calcite which gives an orange glow under UV. A certain percentage of manganese and lead impurities within the calcite produce the fluorescence. Some fossils from the west can have a green fluorescence that is caused by a uranium oxide ion impurity. Also, some fluorescent fossils will phosphoresce after the UV is turned off. I have some Ordovician stromatoporoid fossils that do that.
