Figure 3 in Cenozoic dinosaurs in South America - revisited
Figure 3. Size comparison of the two known snouts of Barinasuchus arveloi with skulls of another large sebecosuchian (Bretesuchus bonapartei), Crocodylus, and selected carnivorous mammals. The white portion of the image of Bretesuchus is intended to indicate the amount of the skull known, not the actual form of the missing portion of the skull. The skull of Crocodylus is scaled to the size of the largest known skull of Crocodylus porosus according to Greer (1974). (Barinasuchus from Paolillo and Linares, 2007, and Buffetaut and Hoffstetter, 1977; Bretesuchus modified from Gasparini et al., 1993; Crocodylus modified from Schumacher, 1973; Andrewsarchus from Osborn, 1924; U. arctos from Allen, 1902; P. spelaea from Gromova et al., 1964; Smilodon from Scheele, 1955.)
