Saurophaganax maximus

Saurophaganax maximus patrolled the semi-arid river systems of Late Jurassic North America as one of the largest apex predators of its era. Giant vertebral flanges anchored powerful dorsal muscles capable of wrestling subadult sauropods and heavily armored herbivores. While paleontologists continue to debate whether its quarry remains represent a colossal distinct allosaurid or a complex composite of multiple species, its fossils highlight the staggering scale achieved by Jurassic theropods.
