Description
Figure 3. Tyrannosaurus (MOR 1125, ''B-rex'') teeth from the lower jaw of this medium-sized skeleton illustrate the extreme range in overall tooth size within one individual. A. A smaller posterior tooth from position #14 from the front of the jaw. B. A larger tooth from position #4 in the same jaw. This demonstrates why shed dinosaur teeth are not a reliable indicator of relative skeletal size and ontogenetic age. doi:10.1371/journal.pone.0016574.g003
