Thank you for viewing. This is a large lower jaw tooth of a great white shark (Carcharodon carcharias), with the longest part measuring 47.2mm. Complete functional lower teeth are common below 40mm, but almost nonexistent at around 50mm. I suspect that great white sharks, which are 4m to 5m long, are fearless and mistakenly believe they can bite anything. They try to catch things with their lower teeth. I think they're a bit foolish. Anyway, this tooth is a functional tooth, and yet it is perfect, with no chips, stains, or anything on the tip of the crown, the left and right serrated edges, the root, or the enameloid of the crown. Of course, there is no smell either. It can be said to be a very valuable and rare tooth. The sharpness and cutting edge of the serrations are attractive, and it is large enough to be displayed as a paper knife or as a work of art. And although the nutrient foramen of this tooth appears to be one, there are actually two holes that spread to the left and right, and two more hidden inside.
