fluorescent fish fossil


blackmoth

Recommended Posts

a freind went for a fossil hunting in China's Beipiao, a well know  lagerstatte of jehol biota ( early cretacous/late jurasic) . By chance he used a home UV light to

check his pieces, just to find that one of them become fluorescent and revealing much more details. this should be a tyipcal Lycoptera davidi or sinensis0d371d74328c2af6ffd728c7258b6d1.thumb.jpg.68ec2de8bdcf5f91efa447f3d0cd3756.jpgb7c222ed6d27c2eb766d21b1d0c6916.thumb.jpg.c7549f1a7abbb045a0b7454399e8af26.jpg0e92c11531f468c8ec9e4d28f76404c.thumb.jpg.dec82ebbb6b98a33f2da0b199d020bb4.jpg641e16c217508a6945e7e0dd54df849.thumb.jpg.9306423725acedbcbf0d4b0abaf5c786.jpg

Very cool!

Any chance for a picture in regular lighting for comparison?

Is he using long or short wave?

i will ask him to see if he knows. 99% chance it is the ordinary uv to check the authenticity of money. 360nm wave length or so. the shorter ones to kill germs, about 280 nm orso, are not safe for such photo taking

Thanks for the extra pictures. :)

I wonder if anyone has ever tried collecting there at night with a UV light?  It seems it might make fossils easier to recognize if they light up like that.

Beginners question :unsure:

 

I thought UV florescence was a sign of some sort of "doctoring" on a fossil?

Not necessarily.  Some fossils (such as your fish) are composed of minerals that are naturally fluorescent.  Others (most) are not.  One would have to examine an authentic specimen (or several of them) from a site to determine if fluorescence is a natural attribute.  If it is not (as is the case for Moroccan trilobites, I believe) then the presence of fluorescent patches in a specimen suggests that the chemical composition of those patches is different from the rest of the specimen, which strongly suggests the presence of materials used to reconstruct or replace missing or damaged areas.

My oreodont teeth glow fluorescent orange!  I was told it has to do with the minerals it uptakes when fossilizing.

I am well impressed with the result of the UV light on the fossil fish and i'm now wondering if i would get any sort of a result on my carboniferous scorpion fossil :zzzzscratchchin: i must get hold of a UV light'

 

Cheers John

I was under this impression as well. Good to know that it’s not always the case. Very cool detail on these fish!

I have seen this effect on live scorpions. 

Not sure it would work with fossils though?

Only one way to find out!

Post results please.

This is the scorpion (Parabuthus transvaalicus)  that I photographed with a uv torch and with a standard torch. 

It was in one of the rest camps in the Kruger National Park, South Africa

One of my Christmas presents was a uv torch initial results on the scorpion fossil doesn't  show the glow just a bit different! but early days and after the holidays i  will post some results on the scorpion and other fossils.
