caldigger Posted February 15, 2018 Share Posted February 15, 2018 Not sure I'm going to buy into that. Something tells me Mastodons and Mammoths didn't burrow too much. 1 Link to comment Share on other sites More sharing options...

abyssunder Posted February 15, 2018 Share Posted February 15, 2018 I'm pretty sure you were inspired by this recent topic. Your specimen has a part of the dentin revealing the Schreger pattern necessary to diagnose proboscidean tusk. Try to measure the angle between the Schreger lines (it will be good to have more samples), then see if they are acute or obtuse. Usually the measurments are made near the dentine-cementum junction. The cementum is a thin layer of the external part of the tusk. In gomphothere tusk the thin cementum layer covers the dentin proximally, but is lost distally by abrasion in life. It's not clear if the cementum overlapped the enamel, also, the enamel is present only in the upper tusks of gomphothere as a continuous band (1-3mm thick) with a width of several centimeters. As far as I can see, the angles in your specimen are obtuse, so it might be from mastodon or gomphotere. The layers in question are the annual/seasonal/weekly/daily increments. 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.

Malone Posted February 16, 2018 Share Posted February 16, 2018 I have almost no experience identifying fossil materials but it seems like wood in the picture. Link to comment Share on other sites More sharing options...
abyssunder Posted February 16, 2018 Share Posted February 16, 2018 Definitely not pet wood.

FranzBernhard Posted February 16, 2018 Share Posted February 16, 2018 I also thought at first sight that this is a piece of coalified wood. But on the third pic, you can see in the lower left corner a relatively fresh break, that is whitish. So no coalified wood. But didn´t recognize it as ivory...

Fossildude19 Posted February 16, 2018 Share Posted February 16, 2018 The Schreger lines seal the deal that it is indeed ivory, and not wood. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Fossildude19 Posted February 16, 2018 Share Posted February 16, 2018 Pretty sure that it's ivory. This is a Florida beach find - not known for fossil wood finds.
