I recently acquired a collection of assorted rocks and minerals. Many of these specimens are from the 70's, 80's and 90's ( am in the US). In this group there is two ammonite in matrix specimens. I believe they are Russian due to them being pyritized. I am having a difficult time finding info about what species and what value these specimens may have. I go to the Tucson show every year and I don't often see ammonites like this. I was told to come here to find the experts! Thank you for your time, I look forward to posting more now that I am a member StoneAgeQuarry

I found what I believe to be baculites and was wondering if there were any suggestions on trying to prep, treat, or leave as is. The one still in the matrix is showing on the back side as just a small rusty dot, but is in direct line with what appears to be the tentacles that are shown oxidized and affixed to the matrix. Any thoughts would be welcomed and appreciated.
