Thank you for viewing. This is an upper jaw tooth of a great white shark (Carcharodon carcharias), with the longest part measuring 30.5mm. It's a tooth with a high crown length to width ratio. The crown's enameloid is white and shiny. The cutting edge has a slightly longer mesial edge, and the serrated edge undulates overall with large and small serrations repeating. Therefore, the sharpness is like a cutter knife. There is no damage at all, it's a perfect tooth.
