Majungasaurus was such a ruthless killed that it even feasted on its own kin. Nevertheless, it could not be found whether they used to hunt live or feast the already-dead relatives. Size: 10 to 13 m. Mass: 3, kg. With its appearance, Mapusaurus looks similar to its close cousin Giganotosaurus. Paleontologists believe Mapusaurus was so lethal that it has hunted all the powerful dinosaurs that ever lived on earth. Besides, direct scientific evidence suggests this ferocious carnivorous predator was 30 feet long and used to hunt in packs.
Mapusaurus has narrow blade-like teeth that were used to slice that prey before tearing it apart. Their close coordination while hunting in groups is attributed to additional strength for extra lethality. Size: 5 to 12 m. Family: Allosauridae. Allosaurus, with its ability to take down prey twice the size of T-rex, is considered among the most deadliest dinosaurs of the Jurassic. This strong-jawed, ambitious, and fearsome three-ton carnivore having sharp serrated teeth.
The three-fingered hands of this fierce meat-eater were tipped with massive talons to capture the prey firmly. Nevertheless, paleontologists believe Allosaurus was not very smart. One of their groups even died by salivating already-trapped and struggling prey in Utah. Size: 12 to 13 m. Known as the South American cousin of Carcharodontosaurus, the bigger and fiercer Giganotosaurus was a three-fingered predator to rival T-rex in size and body structure.
Giganotosaurus had approximately tons and was close to one of the biggest dinosaurs on earth, Argentinosaurus. The overlook appearance was itself very scary and enough to terrorize small-sized dinosaurs. Family: Ankylosauridae. Discoverer: Barnum Brown. Some people might not consider the herbivore Ankylosaurus deadly, but this armored dinosaur had a knobby hundred-pound tail that was used both for defense and attack purposes.
Experts believe Ankylosaurus could cause massive damage to the T-rex by a well-aimed swing of its massive tail. This ability was enough to create havoc and maintain its fierceness in the region.
Discoverer: Chure. Saurophaganax; called the lord of lizard-eaters; was the largest Jurassic theropod and the longest terrestrial carnivore species of all time. With an approximate size of meters, Saurophaganax is known to be a part of the Morrison Formation. Saurophaganax was powerful enough that it could hunt any dinosaur available in its area.
Due to its large size and scary appearance, the predator would eat large sauropods and heavily armored stegosaur. Nevertheless, it has had a dangerous competition for food due to the presence of several deadliest predators like Ceratosaurus, Acrocanthosaurus, and Edmark.
Size: 8 to 27 m. Mass: 22, kg. Family: Diplodocidae. However, the reality behind this long-necked, gentle, and herbivore predator of the late Jurassic period is very interesting and scary. Diplodocus indeed seems to be friendly, but a foot-long tail enabled this foot dinosaur to crack the enemies at hypersonic speeds. In addition to its squishing its enemies with a well-placed stomp of its hind foot, Diplodocus was very good at approaching the preys at gigantic heights.
Mass: 73 to kg. Discoverer: John Ostrom. For years, dinosaurs were thought to be languid and lumbering due to their gigantic size and weight. However, the perception was overhauled with the discovery of Deinonychus, which was a quick-witted pack hunter specifically built for speedy pursuit.
Despite twice the size of Velociraptor, Deinonychus has interlocking vertebrae that enabled the predator to balance its stiffed tail while running. Besides, the prey was disemboweled in its jaw, hands, and retractable toe-claws. Whenever an opportunity arose, Deinonychus would strike on the enemy and chop the prey till death. Size: 90 cm. Mass: 50 kg. Family: Troodontidae. Discoverer: Charles W. This 1. This body structure and composition allowed Troodon to run with greater speed and agility.
Thanks to its huge orb-like eyes that enabled it to hunt nocturnally and see in low-lighting conditions. A group of sharp-minded and agile Troodons could bring down gigantic and powerful dinosaurs with their intelligence and superior vision. Size: 2 m. Mass: 18 to 23 kg. Family: Coelophysidae.
Discoverer: Cope. This light-weight and tiny dinosaur is another example of intelligence overcoming physical strength and might appearance. Weighing only around 44 pounds, Coeplophysis was quite agile and able to take action quickly. They used their boasted blade-like cutting teeth to chop their prey into pieces.

It also had a mouthful of razor-sharp teeth, a superfast top sprinting speed, was 25 feet long, and was extremely smart. It was very maneuverable and hunted in packs. Carcharodontosaurus had smaller arms like the T-Rex, and three air cavities in its chest, making it able to run fast and for a long time.
Allosaurus was massive and smart enough to fight in packs, taking down prey twice the size of Tyrannosaurus Rex. It was a fierce carnivore with sharp, serrated teeth in its gaping jaws. It had three-fingered hands tipped with massive talons.
Velociraptor had a pair of huge sickle claws on each foot. It was three feet tall — about as tall as an adult human — and was light. It did not have a reptilian appearance, but looked more like a bird, and may have even had feathers! At the end of its tail was a thick tail club that could break the legs of even the largest theropods.
Saurophaganax was like Allosaurus, only bigger, nastier, and mightier. It was the grizzly bear of the Jurassic period, challenging Allosaurus, Edmarka and Epanterias.
