Macacoty Posted April 7, 2019 Share Posted April 7, 2019 Found this in the Peace River, Florida. It looks different than any of the countless bone fragments I’ve collected in the past. Looking at photos online I feel like I have a good chance of this being the outer layer of a tusk! Any thoughts? Link to comment Share on other sites More sharing options...

gen Posted April 7, 2019 Share Posted April 7, 2019 Hello, Clearer pictures of the cross section will help identification. Do you see a cross hatch pattern on the cross section? Jay Link to comment Share on other sites More sharing options...
Macacoty Posted April 7, 2019 Author Share Posted April 7, 2019 I don’t see a cross hatch pattern. Link to comment Share on other sites More sharing options...
ynot Posted April 7, 2019 Share Posted April 7, 2019 I do not see a tusk fragment here. It could be a piece of a tooth with enamel covering dentine. 2 Darwin said: " Man sprang from monkeys."

abyssunder Posted April 7, 2019 Share Posted April 7, 2019 It could be a mammoth tooth plate fragment. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

digit Posted April 10, 2019 Share Posted April 10, 2019 Definitely not tusk. The layers in the tusk material are very thin and even and the entire fragment would have a smooth curve to it matching the diameter of the complete tusk from which it came. I've found pieces similar to your object. I don't believe it is a mammoth tooth fragment either. I've seen that shiny black striated surface covering before on some other fragments that I believe were simply unidentifiable bone bits. Doesn't really match my search image for tortoise shell either. Somewhat confident in what it is not but it would be good to hear from someone who has a good feeling for what it is. My vote is bone bit. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
Rockwood Posted April 10, 2019 Share Posted April 10, 2019 I think you would really need to clean a good facet to get a look at the structure of the material on both sides of the transition from dark to lighter colored. Link to comment Share on other sites More sharing options...
digit Posted April 10, 2019 Share Posted April 10, 2019 A clean cross-section (using a rock/tile saw) would provide better visibility of the layers but still may not provide much more information. It's not fossil ivory and so no Schreger Lines will be visible. Though there is not much to provide diagnostic clues to its identification, I'm wondering is someone like @Harry Pristis has seen enough fragments similar to this to confirm it as a particular type of bone (though not a specific bone)?
