This is the upper right jaw of a great white shark (Carcharodon carcharias). It is a large lateral tooth from the first tooth row (the functional tooth in the frontmost row). The enameloid of the crown is smooth, transparent, and a beautiful white. It's a magnificent tooth, with sharpness and cutting ability like a box cutter. The root is also white, harmonizing with the crown. There is one nutrient foramen, but looking inside, it branches into four directions, and the inside of the foramen is neatly processed. ...However, there are traces of battle with prey for the functional tooth, and the tips of two serrations at the lower center of the mesial edge are not clear. Therefore, although it is a large and beautiful upper jaw tooth if you don't mind, I have decided to list it as a "B-grade" item and offer it at a price less than half the original price.
