BobWill Posted November 25, 2012 Share Posted November 25, 2012 I got out to hunt some Texas Pennsylvanian deposits at Lake Jacksboro today and found most of the usual Finis Shale suspects plus a first for me, this Petalodus tooth. So it still holds...I find something new every time I hit Jaxbro! Link to comment Share on other sites More sharing options...

Foshunter Posted November 25, 2012 Share Posted November 25, 2012 That's on my bucket list to hunt one day before I get to old to pick that prize up.

Uncle Siphuncle Posted November 25, 2012 Share Posted November 25, 2012 good find....but i was under the impression that petalodus has a more uninterrupted, continuous cutting edge. maybe stay open minded to something more rare. btw i've taken exactly one petalodus from jax years back, my first ever....2.375 inches of 360 degree perfection!

That may be right but I have seen pictures where there was some scalloping...maybe a bit less than mine. I sent a note to John Maisey and he didn't disagree with my ID but that would be even better if it was "something more rare". Thanks everyone.

Uncle Siphuncle Posted November 25, 2012 Share Posted November 25, 2012 yeah i've had fun being mistaken before when the end result is something more rare! but admittedly, i'm no expert on variation within species, esp in this case....my knowledge base is limited to the 10 or 12 i've found over the years.

BobWill Posted November 30, 2012 Author Share Posted November 30, 2012 A post on the facebook group page for tff suggested this tooth may be Ctenoptychius sp. instead of P. seratodus. A picture on page 129 of "Fossil Shark Teeth of the World" looks just like mine except for the dental band which is wider on mine like the P.seratodus in thair's post. Does anyone have both in hand for comparison to mine? Link to comment Share on other sites More sharing options...
eboe101 Posted December 19, 2012 Share Posted December 19, 2012 Congrats on the tooth! Your find is def. P. seratodus. I am 100% sure. Here is my best one for comparison: Link to comment Share on other sites More sharing options...

Your picture looks like my tooth alright. Problem is, so do some pictures of Ctenoptychius. It's also a member of the Petalodont family but I don't know how to tell them from P. seratodus. I was hoping someone would have descriptions to make a comparison or one of each in hand, to be able to see any differences.

eboe101 Posted December 26, 2012 Share Posted December 26, 2012 Peripristis Ctenoptychius is also a petalodont, but it's vertical ridges are less scalloped and more pointed, which look like extra teeth sticking out of the tooth. Ive seen more blunted examples of Peripristis, but they always have widened spaces between the ridges which are not found on your tooth or on Thair's tooth. Therefore I am certain that you have a P. seratodus tooth. My example is found from my secret site in Eastern Oklahoma. Attached is an example of Periprisitis.

Thanks for helping to draw those distinctions. Luckily, I never changed the label I made with Thair's first ID Edited December 28, 2012 by BobWill Link to comment Share on other sites More sharing options...
