English: Size comparison of the giant allosaurid theropod dinosaur Saurophaganax. Saurophaganax is known from incomplete remains, but its close relative Allosaurus is known from multiple nearly complete skeletons and was used as a basis for the silhouette, slightly modified to fit the proportions of its larger relative. The silhouettes bear a combination of features seen in A. fragilis and A. jimmadseni and are proportionately based on the respective Allosaurus skeletals by Hartman.^[1][2] Their scaling was done based on Chure (1995).^[3] The human silhouette is from File:Silhouette of man standing and facing forward.svg (CC0).
