What was the fiercest dinosaur

The name means giant of the south. From most of the skeleton it is estimated to be about 46 feet long and 8 tons in weight.

We don't measure dinosaurs by height since they didn't stand tall like people. Meat-eaters leaned forward with their tails held high, so they were nearly horizontal over their hips. There is also a gigantosaurus. It is a big plant-eater with four legs, like brachiosaurus. It is known from just a few bones from England found more than a century ago. Q: What is the largest dinosaur bone ever found? A: The biggest single dinosaur bone, by weight, is one of the backbones of argentinosaurus.

One backbone was five feet by five feet and more than one ton in fossil weight. Of course it was lighter when the animal was alive before minerals entered into it to preserve it. The largest bone group ever found was the hip area of the supersaurus, another four-legged plant-eater. Brigham Young University researchers dug it up in Colorado about five years ago.

It is about six feet wide and up to eight feet tall. The biggest skull ever found was the eight foot long skull of torosaurus, a horned dinosaur which ate plants near the end of dinosaur time in the American West. It was discovered by the Milwaukee Public Museum crews about eight years ago. Q: What is the smartest dinosaur? What dinosaur had the largest brain? The smallest brain? A: The smartest dinosaur, if you compare body size to brain size a rough measurement of intelligence is troodon.

Troodon was a meat-eater the size of a man, with a brain as big as an avocado pit. It was not only the smartest dinosaur, but the smartest animal of dinosaur times, including our ancestors — the mammals of the Mesozoic Era. The biggest brained dinosaur of all was probably T. Its brain was about as big as ours but it was many times bigger than us.

Stegosaurus was a tiny-brained dinosaur compared to its size. Its brain wasn't much bigger than a ping pong ball and its body was the size of a truck. Q: How old is the oldest dinosaur?

The Smallest Dinosaur The smallest fully-grown fossil dinosaur is the little bird-hipped plant-eater like lesothosaurus, which was only the size of a chicken. The Tallest Dinosaur The tallest dinosaurs were the Brachiosaurid group of sauropods. What do you get if you cross a Brontosaurus with fireworks? The Fastest Running Dinosaur The speediest dinosaurs were the ostrich mimic ornithomimids, such as Dromiceiomimus, which could probably run at speeds of up to 60 kilometres per hour.

The Oldest Dinosaur The oldest known dinosaur is Saltopus. The Longest Dinosaur Name The dinosaur with the longest name was Micropachycephalosaurus meaning "tiny thick-headed lizard". The Largest Pterosaur Quetzalocoatlus with its wingspan of up to 13 metres was probably the largest pterosaur, and hence the largest flying creature of all time. What do you get if you cross a dinosaur and a skunk? The biggest stinker you ever saw.

How many types of dinosaur were there? How many species of dinosaurs have been found in Britain? Which is Britain's Oldest Dinosaur? Why did the dinosaur cross the road? More Information. Britain was an important area during…. 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.
