Reptile’s teeth found to have covering that helps keep serrated edges razor sharp and resistant to wear

Pretty interesting find. (Not completely sure if this is the right community for this- let me know if you know where else it would be a good fit!)

    Beavers keep growing their yeeth indefinitely too due to being rodents, but the iron buildup probably helps the teeth wear a bit slower.

      The iron content in beaver teeth is concentrated at the front surface so that they are self-sharpening as they wear down.
