Auspex Posted September 28, 2012 Share Posted September 28, 2012 It is hard, with just the crown (no root and no cusps) to be very specific, but I do believe it it Odontaspis sp. This genus is long-lived, so dating your find by determining the species will be difficult.

Auspex Posted September 28, 2012 Share Posted September 28, 2012 Oh, sorry! Odontaspis sp. = Genus Odontaspis, species not determined.

New Members cvi huang Posted September 29, 2012 Author New Members Share Posted September 29, 2012 Thank You! genus Carcharias have only two spiece so it is not easy to determine sp? Example the "Indian sand tiger" are not in Europe? so it is C. taurus? Odontaspididae/Carchariidae maybe same family? funny shark teeth(?) mold-stone this ball maybe piece of necklace? because have two hole (opposite side), but in hole are hard material mutadoxon molar tooth Link to comment Share on other sites More sharing options...
S233 Posted October 2, 2012 Share Posted October 2, 2012 I agree with Paleoc, i just tried to id Dr.j's shark tooth from Summerville and it looks the same Carcharias cuspidata. : ) Link to comment Share on other sites More sharing options...
Paleoc Posted October 3, 2012 Share Posted October 3, 2012 (edited) Thank You! genus Carcharias have only two spiece so it is not easy to determine sp? Example the "Indian sand tiger" are not in Europe? so it is C. taurus? Odontaspididae/Carchariidae maybe same family? They are both in the same family Odontaspidae http://www.elasmo.co...o/ljvc2005.html As survivor says, the species is too old for C. taurus.
