Archaeolamna kopingensis
Age - Cretaceous 
Just shy of an inch, this is one of larger teeth of this species
I've found.
 

Carcharocles auriculatus
I can't really call this one a heartbreaker as it's not broken, the
root is just poorly fossilized.
I estimate this tooth would have been in the 3" range if complete.

Sand tigers
Carcharias cuspidata
