So I polished one side, it did give a much better look. But I don't know what it is. Maybe someone here knows

Fossil fluorescence: UV laser drone fossil hunting
synapsomorphy posted a topic in General Fossil Discussion
(totally new to this forum, let me know if there's a more appropriate place to post this!) Hey all! I found a video showcasing a fossil hunting method that I'm super fascinated by! It's a drone that uses the fact that many fossils fluoresce under UV light to fly around and find fossils autonomously. This seems like an absolutely fantastic way to hunt for fossils over a large area. I have experience with drones and electronics and I'm interested in making a similar drone, hopefully a bit simplified, maybe open-source and user friendly etc. If this method works well to find fossils, getting this tool into the hands of more researchers would be an awesome way to find many more fossils. So I'm looking more into just how effective this method is; particularly how often it is that a fossil is fluorescent, especially vertebrate fossils. I did find this paper that gives some good info but it is largely focused on smaller vertebrates and only from a single formation. Basically any information you have about fossil fluorescence under UV light I'd love to hear! I'm especially interested in figuring out how broad of a phenomenon this is. Do most vertebrate fossils from most formations fluoresce? Is it only smaller fossils or only some formations? The better this method is for finding fossils, the more effort I want to put into making a simple, reliable drone employing the method. I'm also interested in automating the process with machine learning down the line. I read that fossils have a typical fluorescence wavelength that is different from most other things you might find out there, which gives you a clear signal to look for. The eventual result could be: you let a drone go fly around autonomously for a couple hours, recharging it as needed, and then it automatically gives you a list of GPS coordinates to go check out and the images associated with them. (Also, if anyone wants to collaborate on this project, please let me know, whether your skills are more on the electronics/software or paleontology side!) Disclaimer: I'm very aware that drone flight is not allowed in many typical fossil bed areas, definitely won't ever be flying anything without approval.- 9 replies

Fluorescent Meg and Otodus teeth
RhinoWater posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello I have recently purchased an UV flashlight. Under the UV light, I noticed that a couple of shark teeth are glowing fluorescent. I have two megalodon tooth and both are from Carolina; strangely only one tooth glows and the other does not. The otodus tooth fluoresce as well. Is to be noted that all three tooth are from different sellers, but have been reputable for selling genuine fossils. (However, I could very well be mistaken on the genuineness of the teeth) Suspecting a clear coat or vanish has been applied, I have proceeded to use a cotton swab soaked with acetone on both glowing tooth. But the teeth remains unchanged. Is there a reason for the fluoresence (especially on the Meg tooth - where it glows for one and not the other)? Is fluoresence on fossilized shark teeth a normal/common occurence? Is fluoresence on such a large proportion of a fossil an indication of fakery? Apologies for the many questions and, thank you and appreciate any help and advice on the matter.

Hello, Just wondering, when you visit a large Fossil or Mineral expo / fair, do you guys bring your UV light to check if the fossils are real ? If you spot something suspicious on for example a tooth of claw, what will it look like? Im buying my UV light for future purchases. Looking forward to hear what you all take along when you're on the hunt for new fossils. Another question, can you spot a Fossil in matrix with the UV light? Best regards, Egon

While we all can agree that any fossil is amazing, fossils are even cooler under different wavelengths of light. So let's see your favorite fossils that flouresce under UV light! I'll start with a couple. Be sure to show the before and after. Saurornitholestes tooth, Two Medicine Fm, MT
