2ynpigo Posted March 17, 2009 Share Posted March 17, 2009 Attached is a photo of a shark tooth collected from the Whitewater Arroyo Shale Tongue of the Mancos Shale in Sandoval County, New Mexico. The Mancos is Cretaceous in age. I collected what pieces I could find, then glued them back together to repair the piece. Not complete, but these bigger teeth are tough to find. Any ideas on what genus/species? Link to comment Share on other sites More sharing options...
Auspex Posted March 18, 2009 Share Posted March 18, 2009 That really looks like an Otodus. Problem is, they debuted in the Paleocene (as far as I know).

Carl O'Cles Posted March 18, 2009 Share Posted March 18, 2009 possibly a Cretodus Crassidens? Link to comment Share on other sites More sharing options...
hybodus Posted March 18, 2009 Share Posted March 18, 2009 Based on the age, location and ridges (striations) on the cuspslets (side cusps), I would say it's a good candidate for an anterior tooth of Cretodus Crassidens. Could also be Cretodus semiplicatus, but would need a good pic of the other side (labial view). Link to comment Share on other sites More sharing options...

2ynpigo Posted March 20, 2009 Author Share Posted March 20, 2009 Based on the age, location and ridges (striations) on the cuspslets (side cusps), I would say it's a good candidate for an anterior tooth of Cretodus Crassidens. Could also be Cretodus semiplicatus, but would need a good pic of the other side (labial view). Attached is a photo of the back of the tooth. Does this help differnentiate between C. Crassidens and C. semiplicatus? Thanks for any opinions. I have other shark teeth from a different New Mexico locality where small teeth are easy to find. If people are interested in seeing photos of them I can post them sometime soon. Link to comment Share on other sites More sharing options...
