The Amateur Paleontologist posted a topic in Fossil PhotographyA few weeks ago, I posted here some pictures of fossils I took with a digital microscope - here are a few more Pyritized ammonites from the Early Jurassic of Charmouth (south England) This one measures approx. ~1cm diameter Indet. partial plesiosaur tooth from the Cretaceous of northern France. ~1cm tall And since you seemed to like the squid arm hooks, here are some more (from the Jurassic Belemnotheutis antiquus) All those hooks are from the specimen NHMUK 88603, in the invertebrate collections of the Natural History Museum (London) - each hooklet measures between 3mm and 5mm. Hope you liked all these Happy new year!
Hello to Everyone... I'm hoping that someone might be able to advise me about preventing oxidation on a pyritized ammonite. I have no doubt that this question has cropped up before and wondered of anyone had some good advice. I'm reluctant to immerse it in acetone (Seems a tad aggressive?) I know that polishing it will only be a temporary fix. So... Two questions - what can I use to polish it back to a shiny finish and... Two... I do have some clear, low viscosity, pure silicon oil - I use it to fill vintage compasses that I restore. Does anyone know if this would react with the FeS2 in an adverse way? Sadly my knowledge of chemistry is very lacking. :-( I'd love to hear your thoughts...
