dingo2 Posted June 15, 2021 Share Posted June 15, 2021 I found this tooth yesterday and it's not really like anything I've seen in the past. It appears to have been altered at some point after it was shed. In the first picture you can see that the left side is cracked, yet the right side is warped and completely fossilized. Can anybody tell me what causes this? @Troodon Link to comment Share on other sites More sharing options...
hadrosauridae Posted June 15, 2021 Share Posted June 15, 2021 Its called "plastic deformation". It can be seen in lots of fossil elements. 1 "There is no shortage of fossils.

Troodon Posted June 15, 2021 Share Posted June 15, 2021 Yep plastic deformation is the culprit. Caused by the many different process that the tooth sees during mineralization. The loss of porosity with the stresses seen by the overburden can cause the tooth to warp, deform or break. I've have a tooth from the Morrison Fm that has gone through plastic deformation and is deformed. All teeth see it and are affected to different degrees. 2 Link to comment Share on other sites More sharing options...
