Thank you for viewing. This is a tooth from a Great White Shark (C. carcharias), an upper jaw tooth with a maximum length of 40.0mm. The enameloid on the crown surface is white and beautiful. Both cutting edges are straight, and the serrations are complete, alternating between large and small sections. However, the tooth is a preparatory tooth, and both ends of the crown base are broken. Also, the root is incomplete... therefore, it is classified as a B-grade item. It's a shame. If the root were complete, it would probably have been 47.8mm. The tooth crown is formed after the enameloid is completed and the bone-like tissue develops. The crown is almost perfect, though.
