Jurassic Jim Posted October 20, 2014 Share Posted October 20, 2014 Is this Orodus sp? Haven't found a tooth exactly like this one before. Any help greatly appreciated! Link to comment Share on other sites More sharing options...
Al Dente Posted October 20, 2014 Share Posted October 20, 2014 I've seen similar teeth that were identified as Acrodus but I have a Pennsylvanian paper on teeth from Arizona that identifies an almost identical tooth as Orodus sp. Here's a snip from that paper: from: Chondrichthyans from the Pennsylvanian Naco Formation of Central Arizona, 2004. Elliott and others. Journal of Vert. Paleo. 24(2):268-280. The paper does mention that Orodus is probably a polyphyletic assemblage of convergently similar tooth morphologies. Link to comment Share on other sites More sharing options...
Jurassic Jim Posted October 21, 2014 Author Share Posted October 21, 2014 That certainly looks like a match! Thanks for your help Al Dente and for the reference. Link to comment Share on other sites More sharing options...
crinoid1 Posted October 31, 2014 Share Posted October 31, 2014 Jim, You have a really spectacular tooth. I have a part of one that I mislabeled as Protacrodus, so I guess I'd better change it! Thanks for sharing! Gabe I like crinoids...... Link to comment Share on other sites More sharing options...
Jurassic Jim Posted November 1, 2014 Author Share Posted November 1, 2014 Thanks it was a nice surprise. I had only found one small piece like it before. Must not be a very common tooth around here. Link to comment Share on other sites More sharing options...
