The vicious, ruthless, and cunning apex predator, Allosaurus maximus (Saurophaganax maximus). At 40-49 feet long, these voracious carnivores do whatever they want to whomever they want.
...Or so they thought, before meeting Navado, the 65 foot long, 24,000 pound Diplodocus carnegii. Giant sauropods > giant theropods.
Sauropod = the large, long-necked, quadropedal group of dinosaurs. The kind in the Sinclair Petroleum logo. They ranged in size from 15 to 100+ feet, and have been found all over the globe, existing from the Early Jurassic all the way to the Late Cretaceous periods.
Theropod = The major group of bipedal predators, ranging in size from 6 to 50+ feet, found all over the globe and existing through all three major time periods during the Mesozoic era.
