Serack Posted June 22, 2008 Share Posted June 22, 2008 I've found several pointy "lemon like" teeth that had a more knobby root that I figured were from a different species but didn't think I could ID, but this one has a much more distinctive look to it so I thought I'd post it hoping someone would recognize it.

Serack Posted June 22, 2008 Author Share Posted June 22, 2008 I couldn't find anything with a root structure like this one on elasmo but I am wondering if maybe this is one of those odd teeth from the middle of the sharks mouth... Link to comment Share on other sites More sharing options...

Maryland Mike Posted June 22, 2008 Share Posted June 22, 2008 Could it be a cow shark parasymphaseal tooth? Carpe Diem, Carpe Somnium Link to comment Share on other sites More sharing options...
Serack Posted June 22, 2008 Author Share Posted June 22, 2008 you lost me at parasymphaseal... I have never seen a cow shark tooth, but I'm pretty sure that none of the pics I've seen had nutrient grooves. Link to comment Share on other sites More sharing options...
MB Posted June 22, 2008 Share Posted June 22, 2008 you lost me at parasymphaseal...I have never seen a cow shark tooth, but I'm pretty sure that none of the pics I've seen had nutrient grooves. Seems me that the american call cow shark at hexanquiforms shark, as Hexanchus, Notorhynchus, Heptanchrias... and they have symphiseal tooth in their below mandible, like this: Above parasymphiseal cow shark teeths are diferent in my opinion of yout teeth. Look at the gallery, a lot of cow sharks teeth are there . Strange tooth, yes http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...
Auspex Posted June 22, 2008 Share Posted June 22, 2008 The more I look at it, the wierder it is. Beyond the huge root, the lingual surface, at the base of the enamel, seems rather broad and flat. I'm at a loss.

Serack Posted June 22, 2008 Author Share Posted June 22, 2008 So what is a parasymphiseal tooth? Link to comment Share on other sites More sharing options...
MB Posted June 22, 2008 Share Posted June 22, 2008 So what is a parasymphiseal tooth? Knowing I dont speak correclty the english language I try to explain you: symphisis is the union or center of the two mandible bones... more or less the symphiseal tooth is the symmetrycal tooth that occupes the exact center of the complet mandible, exaclty in the union of two bones, usually in the lower mandible. For the upper mandible not symphiseal tooth there, but the first tooth of each bone would be the parasymphiseal tooth. I hope that help you, if not, look some webs where have showed sharks mandiles http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...
Auspex Posted June 22, 2008 Share Posted June 22, 2008 That is perfectly clear to me, MB, thank you!

Guest bmorefossil Posted June 22, 2008 Share Posted June 22, 2008 the tooth on the bottom left is the closest i have to the tooth, it has everything the same except for the parts of the roots that are flattened Link to comment Share on other sites More sharing options...
Auspex Posted June 22, 2008 Share Posted June 22, 2008 I wonder whether the difference in the root might be that the tooth in question is a "death" tooth, rather than shed tooth?

jbstedman Posted June 22, 2008 Share Posted June 22, 2008 I wonder whether the difference in the root might be that the tooth in question is a "death" tooth, rather than shed tooth? Death tooth? What's that? The tooth in question has some of the characteristics of an angel shark tooth, as has already been suggested.

jbstedman Posted June 22, 2008 Share Posted June 22, 2008 instead of the tooth coming out from feeding, the tooth comes out as the shark decomposes Does that make a significant difference in the shape of the root?

Guest bmorefossil Posted June 22, 2008 Share Posted June 22, 2008 Does that make a significant difference in the shape of the root? yes sometimes you can find teeth with extra little pieces on it that you wouldn't find from a tooth that is pulled out Link to comment Share on other sites More sharing options...
Auspex Posted June 22, 2008 Share Posted June 22, 2008 Death tooth? What's that? Most sharks are continuously replacing teeth; the replacements develop in rows, lingual to the row in use and ready to move into place. One of the reasons that there are so many fossil sharks teeth is that individual sharks shed many hundreds of them during their life. My thought was that the teeth that are in a shark's mouth when it dies might have a different looking root, compared to a shed tooth.

I hope that help you, if not, look some webs where have showed sharks mandiles Thanks perfectly clear. Occasionally your syntax is a little off, but in text the meaning is almost always still clear. I envy those who are bilingual. parasymphiseal is probably the reason for its odd shape. the angel shark teeth in elasmo have a root structure that allows them to stand up while this definitely can not Link to comment Share on other sites More sharing options...
