MCG DAWG Posted June 27, 2016 Share Posted June 27, 2016 Getting fairly decent at learning to ID the teeth I find. These confuse me. All have serrations. Two on the left don't have a bourlette. Two on the right do. Any help with the ID? Link to comment Share on other sites More sharing options...
Rustdee Posted June 27, 2016 Share Posted June 27, 2016 (edited) These are all from the Carcharinus genus. Could be bull or dusky sharks in particular. Edited June 27, 2016 by Rustdee 1 Link to comment Share on other sites More sharing options...

Rustdee Posted June 27, 2016 Share Posted June 27, 2016 No problem. It is my understanding that identifying sharks from this genus down to the species can be tricky. Maybe someone else will come along that knows a bit more. Oh and nice finds! Link to comment Share on other sites More sharing options...
sixgill pete Posted June 27, 2016 Share Posted June 27, 2016 I think the best you can I.D. these isolated teeth would be Carcharhinus sp.; Grey Sharks. Most likely are either dusky or bull. Knowing where they were found could help narrow it down to which one, but not positively.

Coco Posted June 28, 2016 Share Posted June 28, 2016 Carcharhinidae is the biggest family of recent sharks, I believe to remember myself that there are at least 30 different species. Most of them have very similar lower teeth, it will be thus difficult to say more on fossil teeth of this family...

However knowing they are from Florida versus say North Carolina would lead me to be more inclined to call them C. leucas (Bull Shark) but that is not 100% positive.
