Shellseeker Posted January 21, 2019 Share Posted January 21, 2019 I have not been hunting the Peace River since October. On Saturday, I was sorting some ziploc bags of finds back in October and found this tiny tooth that I did not know I had. What I do know is that this one looks different from my normal small shark tooth finds. I am amazed that it did not slip between my quarter inch screen.

Hi Jack, I wonder if this isn't a small Carcharhimus sp. reminds me of a falciformis (silky) shark symphyseal tooth (or at least near the mid-line) ? It is quite nice. Sharp and undamaged ! It is the root that looks most unique. Cheers, Brett Here is an extant image.

PaleoRon Posted January 21, 2019 Share Posted January 21, 2019 Looks like it may be a Galeocerdo or Physogaleus symphysial. 3 Link to comment Share on other sites More sharing options...

Shellseeker Posted January 21, 2019 Author Share Posted January 21, 2019 @Brett Breakin' Rocks @PaleoRon Thanks Guys for the Identification and link to the 2008 TFF Thread; I do have both Galeocerdo and Physogaleus in the Peace River. This is my 1st symphysial for either.

A Carcharhinus symphseal wouldn't have as much of a lingual protuberance like that one - something you would see in Physogaleus or Galeocerdo.

siteseer Posted January 26, 2019 Share Posted January 26, 2019 Hi Jack, At 11mm it's probably too big to be a Carcharhinus symphyseal. Link to comment Share on other sites More sharing options...

Jess, what do you think it is ? Is it a normal or pathological tooth from a juvenile Carcharhunus shark? From the thread above launched by Haizahnjager, he had 7 teeth that are as large or larger than the one I have here... and those teeth were (I think) identified as Carcharhinus symphyseals .

siteseer Posted January 28, 2019 Share Posted January 28, 2019 Hi Jack, I agree with Ron that it's either Physogaleus or Galeocerdo, leaning toward the latter if pressed for one. Jess Link to comment Share on other sites More sharing options...

Thanks for the ID, with these tiny ones that don't quite look like anything I have found, it is good to label with the most likely.
