FIGURE 7 in Heterodonty in Tyrannosaurus rex: Implications for the taxonomic and systematic utility of theropod dentitions

FIGURE 7. Positional variation in carina placement and orientation of Tyrannosaurus rex. Right maxilla (A) and left dentary (B) in palatal view (composite photo traces of AMNH 5027). C, the mesial right maxillary dentition of LACM 23844 in labial view (arrows indicate distal carinae, which are forming the distal edges of the labial faces of the teeth by mx3). D, the mesial left dentary dentition of FMNH PR2081 in labial view (arrows indicate distal carinae).
