A Little Help: Hopefully To Confirm; Maybe To Debate

Ok, I have posted this tooth in the past, but I am still wanting to be sure. I believe this is a Galeocerdo aduncus, It was found in Lee Creek spoil material. The thing is it is only 4cm wide at the root and 3cm slant length. Common sense for that size would say Tope shark, however the mesial side of the crown has fine serrations and the nutrient groove while there is not large and pronounced, and it does not divide the root. Please everyone, weigh in on this.

The tooth in question, I believe Tiger Shark (Galeocerdo aduncus) :

A definite Tope Shark (Galeorhinus aff galeus) :

The reference picture I have for Galeocerdo looks like this:

vs. Galeorhinus

So for what a mammal guy's word is worth, I think you've nailed it.

P.S. You wouldn't happen to have a line on where I could get some material like that in bulk quantities, would you?

I assume you mean 4mm wide and 3mm slant height (it's either the smallest or the largest aduncus I've ever seen).
