blackmoth Posted October 9, 2019 Share Posted October 9, 2019 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 sinensis 12 Link to comment Share on other sites More sharing options...

Fossildude19 Posted October 9, 2019 Share Posted October 9, 2019 Very cool! Any chance for a picture in regular lighting for comparison?

FossilDAWG Posted October 10, 2019 Share Posted October 10, 2019 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. Don Link to comment Share on other sites More sharing options...

FossilDAWG Posted October 10, 2019 Share Posted October 10, 2019 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.

t-tree Posted October 11, 2019 Share Posted October 11, 2019 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 i must get hold of a UV light' Cheers John Be happy while you're living for you're a long time dead.

Yoda Posted October 15, 2019 Share Posted October 15, 2019 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 MotM August 2023 - Eclectic Collector Link to comment Share on other sites More sharing options...

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.
