What is the oldest identifiable organic material original to the organism?
joshuavise posted a topic in General Fossil Discussion
Just a silly curious question, but I thought I'd throw it out there. What is the oldest identifiable organic material that could be found? In case this is not phrased correctly, what I mean is "What is the oldest bone we could expect to find that would actually be bone, and not a mineral replacement?" I am aware that Mary Schweitzer may have found blood vessels and osteocytes in a T-rex limb. Are there any other things that may have been preserved in their original state as long, or longer than, this one? -
I got these out of an old house where the previous owners had died..so unfortunately I don't know anything other than that about their origin, etc. I was told that the owner had been some sort of a geological surveyor for the govt. ... or something. Anyway can't figure out what these were. Did a few searches and haven't found anything on my own. Thanks
