Description
Fig. 15. Nasal articulations with maxillae in juvenile Gorgosaurus libratus (nasals at top; TMP 86.144.1) adult Tyrannosaurus rex (nasals in middle and maxilla below; TMP 98.86.01; cast of BHI 2033). The interlocking, staircase−style articulation in the adult Tyrannosaurus rex efficiently transmitted compressional forces and increased the shear strength of the articulation. Dashed lines show the extent of the staircased articulation, and the solid line indicates a projection on the nasals and the corresponding depression in the maxilla.
