Fig. 4 in Physical evidence of predatory behavior in Tyrannosaurus rex

Fig. 4. Graph of tooth dimensions for T. rex, Albertosaurus, and Nanotyrannus, compared with that of the embedded theropod tooth (A and B). When the ICL is plotted against the DCT (A), the three examined taxa are clearly separated, with a large gap existing between T. rex and Albertosaurus, and minor overlap between Albertosaurus and Nanotyrannus. The embedded theropod tooth falls only within the region occupied by T. rex (bold black line in A) and does not overlap with the other two taxa. Graphed ranges of tooth denticles per cm (B) indicates a similar trend, in which the embedded theropod tooth only overlaps T. rex and does not match either Albertosaurus or Nanotyrannus.
