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) :
