Permian fossils?

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?

were these surface collects?  I've seen sun bleaching of Cretaceous fossil bone, so its a possibility.

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

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.
