Shellseeker Posted November 15, 2015 Share Posted November 15, 2015 I found out something new today and decided to share it with TFF members. A TFF member was my hunting partner today. He found some good stuff and a couple of my better finds are below. However, he showed me a 2.42 inch tooth that he found in a SW Florida creek last week. I did not recognize it, although I am sure many (some) ((one)) TFF shark tooth expert will. ID please -- Here are a couple of my shark finds from today. We were out on a prospecting trip and found some gravel.. We will go back there.. I love Sand Tigers and this one came in the last sieve of the day. and I also rarely find verts..

jcbshark Posted November 15, 2015 Share Posted November 15, 2015 Nice finds Jack, to me that looks like an upper Mako: ) Every once in a great while it's not just a big rock down there! Link to comment Share on other sites More sharing options...
bierk Posted November 15, 2015 Share Posted November 15, 2015 (edited) Are my eyes playing tricks or do I see some weak serrations on that tooth? I want to say I see faint serrations like I. escheri has. Edited November 15, 2015 by bierk Link to comment Share on other sites More sharing options...
Shellseeker Posted November 15, 2015 Author Share Posted November 15, 2015 Good EYES , Bierk.... It is not Isurus !!!! The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Grimlock Posted November 15, 2015 Share Posted November 15, 2015 That is a very interesting tooth. My original thought is I. hastalis, but you can definitely see some faint serrations. It could be heading towards C. hubbelli. If that's the case, it is quite a rare find. C. hubbelli tooth The sand tiger and the vert are very nice finds as well.

bierk Posted November 15, 2015 Share Posted November 15, 2015 A good friend of mine has a weakly partially serrated tooth of similar type from the peace so I am very interested in this. Link to comment Share on other sites More sharing options...
bierk Posted November 15, 2015 Share Posted November 15, 2015 I would go with Grimlock at this point. One of the problems I have is keeping up the changes in the scientific naming on teeth in Isurus\carcharodon\et. al. and the related items.

Shellseeker Posted November 15, 2015 Author Share Posted November 15, 2015 http://www.thefossilforum.com/index.php?/gallery/image/30556-great-white-shark-evolution-isurus-hastalis-carcharadon-hubbelli-carcharadon-carcharias/ My hunting partner has sent photos of this tooth to Gordon Hubble, who identified the tooth as Carcharadon Hubbelli, As Bierk has indicated, a few of these are being found in Florida's Peace River and other SW Florida creeks. Gordon originally found this transitional tooth in Peru in the late 1980s. So , I learned about the tooth Carcharadon Hubbelli, and at the same time discovered that possibly I also could find one of these in my favorite hunting spots.

bierk Posted November 15, 2015 Share Posted November 15, 2015 Awesome! Thank you for showing it, and please thank you hunting partner for allowing it to be shown. Link to comment Share on other sites More sharing options...
calhounensis Posted November 15, 2015 Share Posted November 15, 2015 It's hard to disagree with Gordon Hubble on a tooth named after him, but to me it looks more like Isurus. Maybe it is just a position in the mouth that I am unfamiliar with. The few C. hubbelli in my collection look much different. Link to comment Share on other sites More sharing options...
RickNC Posted November 15, 2015 Share Posted November 15, 2015 Upper I. hastalis. I think the "serrations" are just ripples in the enamel. Link to comment Share on other sites More sharing options...
Auspex Posted November 15, 2015 Share Posted November 15, 2015 It is a transitional Mako-Gt. White. Pretty rare!

Foshunter Posted November 15, 2015 Share Posted November 15, 2015 Upper I. hastalis. I think the "serrations" are just ripples in the enamel. I agree with RickNC Tom Grow Old Kicking And Screaming !!"Don't Tread On Me" Link to comment Share on other sites More sharing options...
Paleoc Posted December 3, 2015 Share Posted December 3, 2015 hastalis is NOT Isurus. hastalis leads directly into Carcharodon, so you could call it Carcharodon hastalis (some authors do) or Cosmopolitodus hastis but not Isurus. Isurus and Cosmopolitodus branched off each other somewhere in the early-middle Eocene. It is a Great White, not a Mako. If you were to see one in person, it would look just like a Great White except for the lack of serrations on the teeth. You would not call a sharpnose shark a hammerhead, even though the hammerheads branched off of them and the teeth look very similar. Link to comment Share on other sites More sharing options...
Shellseeker Posted December 4, 2015 Author Share Posted December 4, 2015 Paleoc, Let me make sure I understand, .....It is a Great White, not a Mako. If you were to see one in person, it would look just like a Great White except for the lack of serrations on the teeth............ Here is a GW that I found within 15 feet of the spot my hunting buddy found the tooth above... Clearly a GW. The tooth above "seems" just as clearly a Mako, with the slight ripples or serrations depending on your viewpoint... What you are saying is that the shark that had this tooth would have looked like a GW, not a Mako.. I am learning something new here...
