MichiganMan Posted April 12, 2022 Share Posted April 12, 2022 (edited) My son Jacob and I found some interesting pieces still in grey clay matrix. 1. At first we were hopeful maybe Mammoth Milk Tusk, however He found a beautiful Meg blade amongst the material so probably not. But very heavy, and all are VERY sticky to wet skin. 2. Very heavy for its size and solid with no sign of a marrow channel 3. Very heavy for its size and solid with no sign of a marrow channel 4. Pretty heavy for its size and solid with no sign of a marrow channel, but end is slightly shiny and like chert, also has a tan tinge 5. Very heavy for its size and solid with no sign of a marrow channel, however it seems to be much more worn or weathered on the surface Edited April 12, 2022 by MichiganMan Missed info pertinent to identification about associated fossils found with these Link to comment Share on other sites More sharing options...
MichiganMan Posted April 12, 2022 Author Share Posted April 12, 2022 I just read that mammoths go back as far as 5 million years and megs as recently as 3.6 million years ago so they could be in the same material, however if I’m not mistaken the gray clay material is the phosphate rich material that was associated with ocean sediment. Don’t know if mammoths were known to go swimming at the beach or not Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 12, 2022 Share Posted April 12, 2022 Welcome to the Forum. I'm not seeing any Schreger Lines that would indicate tusk/Ivory. Schreger Line Images EDIT: Missed the tag that said Florida. as Shark13 stated, dugong rib bones are likely in this case. ( This is why it is always best to put the location found in the main body of the message. ) 1 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

SawTooth Posted April 12, 2022 Share Posted April 12, 2022 Probably dugong rib bone, Florida's full of it. 1 Link to comment Share on other sites More sharing options...
Bone Daddy Posted April 12, 2022 Share Posted April 12, 2022 Agree with dugong rib sections. I've found some just like those. Those are from a dry land site. You see a lot of them in the rivers and they have been stained black or brown by tannins. Link to comment Share on other sites More sharing options...
MichiganMan Posted April 12, 2022 Author Share Posted April 12, 2022 Material was no longer in situ as it had been excavated some time before and we weren’t sure if it was from that site or near it. But it came from Auburndale, Florida area. Our first time seeing duogong bone all white, and seemed heavier than pieces we’d found on Onslow Beach North Carolina before. I attempted to polish one end enough to see the structure, pictures attached. Link to comment Share on other sites More sharing options...
MichiganMan Posted April 12, 2022 Author Share Posted April 12, 2022 Now we know! Thank you! Link to comment Share on other sites More sharing options...
Bone Daddy Posted April 12, 2022 Share Posted April 12, 2022 Dugong rib will also show structures like tree rings in cross-section, just like what's shown in the last set of photos. Link to comment Share on other sites More sharing options...
