Sélacien34 Posted May 17, 2014 Share Posted May 17, 2014 (edited) You have found symphyseal teeth, the one to the left looks like Cretalamna symphyseal tooth. Edited May 17, 2014 by Sélacien34 Link to comment Share on other sites More sharing options...
JohnBrian Posted May 17, 2014 Share Posted May 17, 2014 You have found symphyseal teeth, i'm not sure about the specie, i have to look at it. I have seen the term "symphyseal" used before but I haven't a clue what it means. Somebody please explain? ---------------------------------------------------------------------------- John Link to comment Share on other sites More sharing options...
Sélacien34 Posted May 17, 2014 Share Posted May 17, 2014 (edited) The term "symphyseal" describes the teeth which lie at the level of the symphysis of the shark jaw, joint cartilage is located on the center of the jaw. The parasymphyseal teeth are slightly on the sides of the symphysis. Edited May 17, 2014 by Sélacien34 1 Link to comment Share on other sites More sharing options...

Tennessees Pride Posted May 17, 2014 Share Posted May 17, 2014 You might have some Goblin shark in the mix...(top, center, and right)...tooth at the top looks like it may have some striations running down the tooth itself...which may indicate Goblin....also where root meets tooth, there is a small notch in the center of the root...Goblins have that best i know of... --- Joshua tennesseespride@gmail.com Link to comment Share on other sites More sharing options...
