6000 yr old Incense Burner Hongchan Dynasty from Chinas Pyramids

Got some suggestions for what my Hongshan dynasty skull may have been used for by @RavensWillReplaceUs so i decided to try it. It may have been a tomb marker that may have also been used as an cover for a incest burner. also big thanks to @drrahilakurdi5943 my number 1 fan from Pakistan!
