Shellseeker Posted September 23, 2014 Share Posted September 23, 2014 I am sorting (and enjoying) the normal finds in ziploc bags from last Spring and Summer and finding some fossils that definitely deserve my attention. Including these 2 shark teeth -- I think one is relatively rare and hope that the other may be the same species. So what are these 2, and if different, how so?

MarcoSr Posted September 23, 2014 Share Posted September 23, 2014 They both look like Alopias, Thresher. Marco Sr. "Any day that you can fossil hunt is a great day."

Shellseeker Posted September 23, 2014 Author Share Posted September 23, 2014 Thanks to both. I was pretty certain that the smaller one was Thresher, but originally I tossed the larger worn one in with the Tigers. Where I hunt, Tigers are pretty common and Threshers are rare. Small (15mm) Threshers are uncommon, medium sized ones like these are rare and large (40 mm+) are 1 in 20000 or so. So if I considered the slightly larger one as a very worn (missing serrations) Tiger, I tried to look for shape differences -- there are few. I am just as happy to add both to the Thresher bottle.

sixgill pete Posted September 23, 2014 Share Posted September 23, 2014 Shellseeker, I agree with Marco that both of these teeth are threshers. Probably Alopias superciliosus. I always get very pleased when I find some of these teeth. Great finds.

Fallingfossils Posted September 24, 2014 Share Posted September 24, 2014 (edited) Shellseeker, I agree with Marco that both of these teeth are threshers. Probably Alopias superciliosus. I always get very pleased when I find some of these teeth. Great finds. Agreed! One of my favorite teeth to find. It must be a combination of the species and the shape/look of the teeth. They are some of the best looking, in my opinion. Edited September 24, 2014 by Fallingfossils Link to comment Share on other sites More sharing options...
