prod Posted October 26, 2018 Share Posted October 26, 2018 Hello. Found in permafrost, Yakutia, Russia. I made a bet with a friend that is a mammoth Tusk, and he claims it's not a Tusk! Thank you. Link to comment Share on other sites More sharing options...

Agree the tip ends are unusual in their growth and almost seem to be branching. "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
abyssunder Posted October 26, 2018 Share Posted October 26, 2018 I never had the opportunity to study proboscidean deciduous or very young permanent tusks, but I'm inclined to believe that the specimens in question might be something like that. Also, I could be wrong. The possible scenery might be something like: Both "tusks" have lost the tip cup of enamel, so what may be visible in the tapering end might be the dentine following the same shape of a complete tusk-end with the enamel preserved, maybe more branched. Next in line, might be the cementum cover of the dentine running along the tusk, narrowing to a thin end where the pulp cavity is larger. Thanks to Eric, Harry, and the authors of the document mentioned above (D. Moll et al. 2018), making the collected specimens available for further study.

prod Posted October 27, 2018 Author Share Posted October 27, 2018 the base of the Tusk is called alviola. it's always hollow. These samples are of interest for science. They can indicate the reason why the mammoths in life sharpened(stitch) the ends of his tusks. Yes, part of sheath tip of the tusks broke loose, but in doing so she revealed the tips of the tusks. I'm assuming these are mammoth milk tusks, which means they've been replaced by permanent tusks. Link to comment Share on other sites More sharing options...
