I bought a pack of dinosaur bone rubble ( Sauropod allegedly) to make up the min price on a order of rock. Polished up a bit on my flat lap and did a fluorescence scan just on the endogenous fluorescence. Turns out to glow all over the shop and makes a great test slide . The microscope tracks a laser spot across the sample and measures the fluorescence produced at whatever wavelengths you set. The first image is one frame at higher res, the field of view is about 60 microns. but I was testing the frame stitching so the second image is a tiled scan - same res. The original files are 3d too tho
This was my second time visiting this well-known Late Carboniferous, Kasimovian stage (305-7mya) spot on the NW edge of the Illinois basin. Here are some things I found. Some large brachiopods. After splitting some rocks, came across this nice tooth. I kept both halves for careful extraction/reassembly at home, which took at least a few hours. I don't know much about shark teeth and after researching, and from what I can glean from what scarce information is available, I think it's a Holocephalia subclass, Chimaera tooth. Possibly Cochliodus sp...? It
