This 3D model of the semi-aquatic, predatory American alligator, Alligator mississippiensis (MUVC AL008) found in southeastern North America illustrates how having such a flat skull changes the orientations of jaw muscles to be in rather horizontal or diagnoal orientations compared to their ancestors.

This 3D model of the partly terrestrial, predatory living Cuvier’s Dwarf Caiman, Paleosuchus palpebrosus (FMNH 22817) from South America. Although crocodylians have markedly flatter skulls than their ancestors, Paleosuchus has a markedly more vertical skull than its living relatives and its temporal muscles are also rather vertcially oriented.

This 3D model of the terrestrial, predatory crocodylomorph Prestosuchus chiniquensis (UFRGS PV0629T) from the Triassic Santa Maria Formation in Rio Grande du Sul, Brazil shows the primitive condition of temporal muscles being largely vertically oriented as well as relatively vertically oriented pterygoideus muscles compared to later crocodylomorph species.
