A. grandis or Isurus?

[Bails]

Hi all,

 

I found a couple tooth today on morning hunt in Charleston, SC. 
 

I am fairly certain the first tooth (in the first two pictures) is A. grandis. 
 

However, I am unsure if the second tooth (in the last two pictures) is A. grandis, alopias sp., or isurus. 
 

I had this discussion with @MarcoSr in another thread but they resemble each other so much I still can’t tell with my eye. 
 

happy to post additional pictures if needed and thanks in advance!!

In the future will you be able to crop your photos please ? There is too much empty space around, and this would probably make the views even bigger.

Cropped and brightened 

 

Any opinion on the question asked @Coco?

Thanks for pics

 

I don't think you have an Isurus here. But @MarcoSris a better specialist !

I would say both are threshers, Alopias. As far as species I'm not too certain. A. grandis seems to be a good match though
