Harry Pristis Posted September 4, 2014 Share Posted September 4, 2014 No, I have not tested the UVA flashlight in the field. I wonder if rattlesnakes fluoresce in UVA . . . If they don't fluoresce, it might be easy to walk into one in the weak illumination from the UVA flashlight. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
nass Posted July 23, 2015 Share Posted July 23, 2015 First post here - I'm very uninformed about fossils but I am familiar with UV photography. My 11/y old daughter and I went for a walk and I found this in grey chalk. Of the fossils we found (20) this is the only one that fluoresces under UV, so I thought it might be a shark's tooth? Thanks for any help. UVIFL with filtered 365nm torches Link to comment Share on other sites More sharing options...
Auspex Posted July 23, 2015 Share Posted July 23, 2015 It has a generally suggestive shape, but I would not expect a shark's tooth to exhibit crushing (if I am seeing it right).

Troodon Posted July 24, 2015 Share Posted July 24, 2015 Same here I don't see a tooth. You may want to carefully remove some of the matrix, chalk, around the object and see if it reveals anything. Link to comment Share on other sites More sharing options...
nass Posted July 24, 2015 Share Posted July 24, 2015 Thanks folks, appreciated. As I say, very uninformed - thought the UVIFL might be a definitive pointer but who knows, bound to be something else. Matrix manipulation isn't something I've done before so I'll have a shot. Thanks again. -Johan Link to comment Share on other sites More sharing options...
FossilDAWG Posted July 24, 2015 Share Posted July 24, 2015 It looks more crustacean (crab claw-ish) than toothy to me. Don Link to comment Share on other sites More sharing options...
nass Posted July 24, 2015 Share Posted July 24, 2015 That's what I thought at first Don, before shining a torch at it. Its structure seemed to suggest that... cracked bits of exoskeleton... Link to comment Share on other sites More sharing options...
