  Dr. Bretton Kent is a fossil shark expert. He is a professor of paleobiology at the University of Maryland. There is nothing I could add to his information.

    Everyone can improve upon their data entry, even experts. I wonder if this has since been published on, @bkent? Let us know and we can link in the publication.
