Serrated Kem Kem Teeth

[mattman10]

Was hoping to get a little help narrowing down an ID for two strange teeth from the Kem Kem Beds.  I have no idea what the first might belong to, but wondering if the second might be some sort of serrated croc tooth?

 

Hope the pictures are clear enough. 

 

The first tooth measures a tad over 9mm and serrations are 3 per mm.

 

This second one is 14mm with 2.5 serrations per mm.

 

Both teeth look to be complete, minus the root.

One possibility is from the croc Hamadasuchus rebouli which has serrated teeth and it's posterior teeth look similiar to yours.  I cannot find closeup pictures of these teeth to verify.  Having said that there may be other crocs in the Kem Kem with similiar teeth since new discoveries are constantly changing our knowledge.

Thanks Troodon! I think you may be right, I guess both are most likely croc teeth.
