Fossil Nipple

I've been around for a long time and I've become mineralized. When archeologists first found me, they weren't exactly sure of what I was, but after careful study, they determined my true identity. It's been so long that I don't really remember the gender of the person to whom I belonged. The rest of the body has not been located. I'm not sure what happened to it because a great deal of time has passed, eons, ages. I hope it is a case of random scattering, and that my person did not meet up with some prehistoric version of Ed Gein.
