Fossiljones Posted February 2, 2019 Share Posted February 2, 2019 Hi all, I realize it would be highly unusual, but could this be fossilized marrow inside this bone frag? I recovered this piece during a South Carolina River fossil dive. Link to comment Share on other sites More sharing options...
Wolf89 Posted February 2, 2019 Share Posted February 2, 2019 I do think it is bone, but I am not sure if I would call that marrow. Link to comment Share on other sites More sharing options...
Rockwood Posted February 2, 2019 Share Posted February 2, 2019 It's possible that there could be minute traces of the elements that made up the marrow, but more (perhaps not most) correctly it is the marrow cavity that is preserved. 2 Link to comment Share on other sites More sharing options...
Rockwood Posted February 2, 2019 Share Posted February 2, 2019 If you can find a way to thin section it and study it under a microscope I would love to be proven wrong. My ID was primarily based on the relative odds I guess. Link to comment Share on other sites More sharing options...
ynot Posted February 2, 2019 Share Posted February 2, 2019 The internal structure of bone is often preserved. I do not see that in this piece, it looks like the bone was broken before burial and has been filled with sediment. 1 Darwin said: " Man sprang from monkeys."

It could have been broken when the animal hit the side of a deep cave with a pool of anoxic hot water saturated with silica which mineralized the marrow cells in a rare case of exceptional preservation too. The odds are just not favorable. Link to comment Share on other sites More sharing options...

Jeez, I hope I don't get dinged by the State for failing to include it on my Quarterly Artifact report.... (In order to comply with South Carolina collecting (while diving) regulations, you are required to procure a "Hobby Diver" license. In order to keep said license, licensed Fossil/Artifact divers must submit two reports every quarter, one for Fossils, and one for Artifacts).

That makes it not only a "Fossil", but an "Artifact" as well! You have to know that @Rockwood likes to propose very unlikely scenarios to muddy the water (so to speak). As far as I can tell there is no marrow preserved in the piece shown, and the infill looks like normal sediment not what would be deposited in a hot springs. Edit.... I do not know of any hot springs in eastern NC either. (modern or ancient). Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
