Thank you for viewing. This is a great white shark (Carcharodon carcharias) tooth, with a maximum length of 45.6mm, making it an extra-large upper jaw tooth. As you can see in the image, the distal side is longer than the mesial side, and the crown appears to lean distally. The serrations along the cutting edge are perfect and delicate, without a single chip. When held in the hand, the sharpness and cutting ability are more stable than a cutter knife. The enameloid on the crown surface is as beautiful as white porcelain and has a very glossy appearance. The root is also white, harmonizing with the whiteness of the crown. There is a clear single nutrient foramen in the center of the root, and the inside of the foramen has five openings, like fingers spread out. Of course, there is no dirt or odor whatsoever. ...Honestly, it's a wonderful tooth.
