Fig. 9 in Fused and vaulted nasals of tyrannosaurid dinosaurs: Implications for cranial strength and feeding mechanics

Fig. 9. Comparison of theropod nasal strengths at multiple transverse sections. Horizontal (Iy) and vertical (Iz) second moments of area of nasal cross−sections of Allosaurus fragilis (upper two graphs) and tyrannosaurids (lower two graphs). Second moments of area are proportional to lateral (Iy) and vertical (Iz) bending strengths. X−axes of graphs show relative position of slices along the long axes of the bones: 0.0 is posterior and 1.0 anterior.
