Hey fellow vultures, can I ask your advice? I collected a mummified squirrel last year, and rotted it down and degreased it, or at least I thought I had, so I put it in peroxide for a day, and most of the bones turned out great like those on the left, but some still have a pinkish/brownish color to parts of them. Am I correct that these need more degreasing? Or is this just a color abnormality? If I leave them as-is are they likely to get smelly again? Do they need more time in peroxide??

Sorry for the newb question. My normal source for silly vc questions has disappeared :(
