10. Velociraptor 6 ft long, 100 lbs Despite their small size, Velociraptors were among the most dangerous dinosaurs. They had intelligence, killing claws, and speed. They also hunted in packs. 9. Ceratosaurus 23 ft long, 1.5-2 tons Ceratosaurus was a pretty large carnivore. It hunted in pairs and trios. Ceratosaurus also had some of the largest teeth compared to body size of all the large predators, 6 inches long! 8. Carnotaurus 25 ft long, 2 tons Carnotaurus was slightly larger than it's earlier cousin Ceratosaurus. Like Ceratosaurus, Carnotaurus had horns on it's head.

Giganotosaurus 43-46 ft long, 7-8 tons Giga and Car were very similar in body design, but Giga was somewhat larger and smarter. Giga likely hunted in packs to bring down large prey like titanosaurs. Giganotosaurus was the largest carnivore that ever lived in the southern hemisphere. 1. Tyrannosaurus rex 45-50 ft long, 7-9 tons Tyrannosaurus was by far the deadliest dino of all time. It was huge, strong, fast, and intelligent. T-rex had a bite force of up to 9 tons per square inch and likely hunted in packs.
