Still_human Posted July 2, 2020 Share Posted July 2, 2020 These aren’t exact examples, but they’re very good representations as to what I mean- -Is it rare to find Permian fossils with that bone colored white glossy surface patina, like right here?

hadrosauridae Posted July 2, 2020 Share Posted July 2, 2020 were these surface collects? I've seen sun bleaching of Cretaceous fossil bone, so its a possibility. "There is no shortage of fossils.

DPS Ammonite Posted July 2, 2020 Share Posted July 2, 2020 The bone might have been replaced with quartz/opal. I have seen similar newer silicified bones deposited in lacustrine/river sediments with nearby volcanic rocks. If silica replaced the bone material, the dark phosphatic material is gone. What is the hardness of the light areas? Does a steel knife blade scratch it? My goal is to leave no stone or fossil unturned.

I don’t know anything about these bones, they’re just examples of the surface of other ones I don’t have pictures of Link to comment Share on other sites More sharing options...

I don’t have them, they’re not mine:/ yeah, I’ve seen many fossils with that surface color texture, I just don’t know if I’ve ever seen Permian fossils with that surface.
