Thank you for viewing. This is a lower jaw tooth of a great white shark (Carcharodon carcharias). The longest part measures 41.1mm, and it is a functional lateral tooth. The crown is smooth, and the left and right sides are almost the same length, forming an isosceles triangle, making it a very well-balanced tooth. The serrations are unusually uniform in size, and their sharpness and cutting ability are like a cutter knife. The root is robust, clearly indicating that it is a functional tooth. However..., one serration at the tip is missing. Complete lower jaw teeth are rare in larger specimens. I received this tooth from a friend, and I didn't notice it until I took the pictures. ...So, it's a shame to classify it as a B-grade item, so I've decided to offer it as an A' item at a low price. It's less than half the original asking price. The last image shows it on my hand, and 41mm is quite large. Please check the condition in the images.
