Roz Posted January 11, 2013 Share Posted January 11, 2013 This is what I think might be sponge but I am not certain. I am basing it on the area where the white material isn't present but where it once was.. I know I have seen the area under the white before but cannot remember where.. Any help would be appreciated.

RichW9090 Posted January 11, 2013 Share Posted January 11, 2013 There is a dermal bone look to it. It also brought to mind bryzoa. The plural of "anecdote" is not "evidence". Link to comment Share on other sites More sharing options...
Roz Posted January 11, 2013 Author Share Posted January 11, 2013 Wow, bone had never crossed my mind but maybe because the bright white was throwing me off.The area under the white brings to mind bryzoa now that you mention it..Thanks for the ideas ..It's Pennsylvanian period Welcome to the forum!

Indy Posted January 11, 2013 Share Posted January 11, 2013 If I was in doubt ... I would do the tongue test thing However...You might try lightly moistening your finger Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

Sticky lil' pup.. Thought I would be wearing it hanging from my tongue.. I had already cleaned it with soap and water. Thanks, I didn't think of the tongue test.. Welcome to the forum!

Missourian Posted January 12, 2013 Share Posted January 12, 2013 It could be a tooth (Sandalodus?) that broke wrong. Context is critical. Link to comment Share on other sites More sharing options...
Roz Posted January 12, 2013 Author Share Posted January 12, 2013 It could be a tooth (Sandalodus?) that broke wrong. The shape isn't far off but would a tooth have that texture underneath the enamel? The enamel would have been very thin then as the white tests positive for bone. Unfortunately I only found the half I have.. If the other side would have been found then we could rule it in or out..

Indy Posted January 12, 2013 Share Posted January 12, 2013 It could be a tooth (Sandalodus?) that broke wrong. Bone or tooth ... both will stick to the tongue If I were guessing ... I would agree with Missourian that the likelihood we are looking at a tooth ... bad break.

Missourian Posted January 12, 2013 Share Posted January 12, 2013 (edited) Crusher teeth for comparison: The little 'polka dots' appear to be canals within the enamal that became exposed as the tooth wore down. I'm not sure if or how they continue into the underlying root. Edited January 12, 2013 by Missourian Context is critical. Link to comment Share on other sites More sharing options...
Auspex Posted January 12, 2013 Share Posted January 12, 2013 It could be a tooth (Sandalodus?) that broke wrong. Is that a Bradyodont? If so, is the internal structure right for that?

RichW9090 Posted January 12, 2013 Share Posted January 12, 2013 You sem to use the tongue test differently than I am used to. We use it in the Southwest to determine if something is a modern bone (the tongue sticks to it) or a fossilized bone (the tongue does not stick to it). The plural of "anecdote" is not "evidence".

Roz Posted January 12, 2013 Author Share Posted January 12, 2013 Rich, I have never heard of it that way before.. This explains it better than I could..

I'm not sure if or how they continue into the underlying root. I have some a few of that age teeth and some in terrible shape.. I am thinking of seeing if I can get a break it in that would show what is underneath.. I think that would be helpful.. Welcome to the forum!

I'm not sure if or how they continue into the underlying root. This is a tooth chip of the same age that was already broken so I got a few shots of it.. You could be right. The material near the enamel does look similar to me.. I am feeling confident that is what it is so thanks all! Welcome to the forum! Link to comment Share on other sites More sharing options...
