Shark Teeth ID Needed

Over the weekend I acquired some shark teeth that I would like to have ID'd. The teeth in the upper left are from Argentina which is about as much as I can tell you. The bottom right are from Sharktooth Hill in California. post-15927-0-67523500-1463584453_thumb.jpg

Number 1 and 2 aren't from Argentina, they are Otodus from Morocco. Six and 7 are Cosmopolitodus planus, 5 is Cosmopolitodus hastilis (probably 4 too). Not sure where to put number 3.

The teeth from Argentina look to me like otodus obligus. The ones from Bakersfield appear to be makos. Atleast two different species. I'm not sure the correct names.

Anybody have an idea on number 3?

I'd say 3 is a lower tooth. If guessing I'd say young I. Hastilus.

No.'s 1 & 2 are Otodus from Morocco (as others have stated) but also appear extensively restored

Thanks!

...but also appear extensively restored

I thought they looked a little off. They were given to me so its of no consequence that they aren't all original. I still am quite fond of them. :P Thanks for the consensus. :)
