Actually Max, I had found another small posterior meg that I gave to another friend. But I was wondering if you were going to post this one. 

Ah ok

I’ve been blown away at the quality of yalls teeth. Thanks for sharing! I do not yet know how what many species posteriors look like but here’s a few! (Forgive me if any are not posteriors)

Here is one of my favorites. A Brownies beach, posterior meg. I cleaned up the beach pretty well the day I found this. I found another one about half this size and a few nice makos.

Take a look at the dentition set(s) on this site...

http://naka.na.coocan.jp/

They will show You the nature of posterior shark teeth.

 

Nice little meg You have. The other three are not posterior as far as I can see. And Your "tiger" is a Galeorhinus  sp.

The snaggle is not, the Meg is, the 1st tiger is, the tiger-like (aduncus) is not...

Do not tigers have a more rounded leading edge?

I think that is how we identify posterior teeth.. long straight leading edge,  Maybe this is not Galeocerdo cuvier .

If You look close at Your tooth You can still see the inherent curve of the leading edge. I agree that it is a posterior G. cuvier.

I also agree that  @eannis6 "s tooth is probably a posterior tooth, just think it is a different shark. (but I am not great with IDs).

 

Maybe @MarcoSr @Al Dente @siteseer can give an opinion on eannis6's "tiger"  tooth.

Here is another Sharktooth hill posterior shark tooth.

This one is from a Heterodontus and is pictured next to a lateral tooth. The posterior tooth is 3mm wide.

Well, No additions for a while so I thought I would add a recent find.

This tooth came from the Sharktooth Hill nano matrix I have been searching.

It is 2 millimeters by 1.5 millimeters.

The smallest Carcharodon hastalis I have seen.
