Kem Kem Sauropod tooth- Diplodocid indet ?

[fossilsonwheels]

Both of the Kem Kem sauropod teeth I have are Titanosaurid teeth so I am looking for a Diplodocid tooth. While checking out the auction site that shall not be named, I saw this tooth. It looked quite a bit different than the teeth I have and quite a bit different than the other teeth on the auction site. It has a very peg like shape to it and lacks the tip does not have that wear pattern I have seen on the Titanosaur teeth. I could be wrong but the enamel looks different too.

My initial thought is that this is a tooth from the Diplodocid indet present in the Kem Kem. These are the only pictures the seller had and I am not really buying so I do not want to ask for more. This is more educational for down the road when I buy one.

 

Any thoughts ?

This is a Titanosaurid tooth.  The Rebbachisaurid teeth are much smaller and faceted
