Carl Posted July 15 Share Posted July 15 I agree that they all look like real teeth but none look like Xiphactinus to my eye. 1 Link to comment Share on other sites More sharing options...
Randyw Posted July 15 Share Posted July 15 I agree they are real teeth but I’m not sure about the i.d. Given… The teeth can be a bit troublesome to identify and easily confused with the teeth of more common Enchodus. Xiphactinus teeth have a double cutting edge and are fluted (flat sections). The fluting is subtle and a strong light may be needed to see it. Link to comment Share on other sites More sharing options...
