Is this a Carcharodontosaurus tooth?

[Orni]

Is it really from Carcharodontosaurus or some other theropod? 
Information I got with it,

Carcharodontosaurus saharicus 

Kem Kem Beds, Morocco

[Troodon]

I believe its a Carcharodontosaurid.  No way to determine if a Carcharodontosaurus or Sauroniops
