The teeth of Trix are one of the skeletal areas where she is less intact. Most of the teeth in the mount are replacements from other Tyrannosaurus rex or replicas (from other T. rex). However, in the photo, the tooth with the shadow falling on it (2nd tooth from right) is an original Trix tooth, excavated from the Naturalis dig in the Hell Creek Formation, Montana, USA.
