What is this shark tooth?

[Deinocheirusmaster!]

I have these shark teeth in my collection but I’m not quite sure what the one on the left is. I think it may be Otodus but I’m not sure. Can anyone identify what it may be? Note that the side cusp is broken.

I can make a few guesses but nothing solid. May we please have the formation you found it in and location? Without that and merely based on shape I would guess Cretolamna Appendiculata, but don't quote me on this. I don't have much experience with what I deem to be Cretaceous teeth, so I am probably wildly off. The picture below are some Moroccan versions of Cretolamna Appendiculata. It could also be Otodus, which is a far more likely guess due to root shape. But feel free to disagree with me as you wish.

All look moroccan.  A good reference for this material.  Click on name to see images
