More Details
The Tyrannosaurus Rex and Triceratops were two iconic dinosaurs of the Late Cretaceous, often depicted as predator and prey. T. Rex was a fearsome carnivore, while Triceratops was a heavily armored herbivore. T. Rex, the "king of the dinosaurs," weighed up to 9 tons and stood 12-15 feet tall. Its powerful jaws and bite force of ~12,800 psi made it one of the most formidable predators of all time. Despite its size, T. Rex could reach speeds of 12-20 mph, making it a deadly hunter. Triceratops, on the other hand, was a large herbivore weighing 6-12 tons and standing 9-10 feet tall. Its three horns and large bony frill provided excellent defense against predators. Triceratops could charge at speeds of up to 20 mph, using its horns to fend off attackers. In a hypothetical encounter, T. Rex would rely on its powerful bite and predatory instincts to take down Triceratops. However, Triceratops's horns and frill would make it a challenging opponent. While T. Rex could inflict serious damage, Triceratops's defensive capabilities would make it a formidable adversary. Final Verdict: T. Rex Wins 7/10 Times!
