sixgill pete Posted April 26, 2012 Share Posted April 26, 2012 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.

MammothPaleoGuy Posted April 26, 2012 Share Posted April 26, 2012 (edited) 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?

siteseer Posted April 27, 2012 Share Posted April 27, 2012 I assume you mean 4mm wide and 3mm slant height (it's either the smallest or the largest aduncus I've ever seen).

sixgill pete Posted April 27, 2012 Author Share Posted April 27, 2012 I assume you mean 4mm wide and 3mm slant height (it's either the smallest or the largest aduncus I've ever seen). you are absolutely correct siteseer thats mm not cm. If it were cm that would be huge. Don't know how that got by me. Thanks for pointing that out!!!!!!!
