20 Terrifying Dinosaurs You’re Glad Are Extinct
Показать описание
Dinosaurs went extinct about 65 million years ago after living on Earth for about 165 million years. They lived on all of the continents and died out. If dinosaurs didn't go extinct, mammals probably would've remained in the shadows and humans probably would've never been here. We will tell you the salvation stories of some gigantic dinosaurs who lived on this planet. Here are the top 20 terrifying dinosaurs you’re glad are extinct:
1. Gorgosaurus:
This terrifying extinct animal lived in western North America during the Late Cretaceous Period, between about 76.6 and 75.1 million years ago. Fossil remains have been found in the Canadian province of Alberta and possibly the U.S. state of Montana.
Gorgosaurus lived in a lush floodplain environment along the edge of an inland sea. It shared its general body plan with all other tyrannosaurids. Its massive head was perched on the end of an S-shaped neck. In contrast to its large head, its forelimbs were very small.
2. Dracorex
They are most terrifying for having a large, bony dome atop its skull, up to 25 cm thick, which safely cushioned its tiny brain. The dome's rear aspect was edged with bony knobs and short bony spikes projected upwards from the snout. The spikes were probably blunt, not sharp.
The skull was short, and possessed large, rounded eye sockets that faced forward, suggesting that the animal had good eyesight and was capable of binocular vision. They had a small muzzle which ended in a pointed beak. The teeth were tiny, with leaf-shaped crowns.
3. Triceratops:
This terror bird lived in the late Cretaceous period, around 66 to 68 million years ago. The climate was warm and dry and there were numerous volcanoes.
Bearing a large bony frill and three horns on the skull, and its large four-legged body possessing similarities with the modern rhinoceros, Triceratops is one of the most recognizable of all dinosaurs and the best-known ceratopsid. It was also one of the largest, up to nine meters long and twelve tons in weight. Animal extinction are sometimes blessings.
4. Giganotosaurus
Today, Giganotosaurus is believed to have been slightly larger than T. rex, though even it ranks behind Spinosaurus in size among the meat-eating dinosaurs. It should not be confused with Gigantosaurus, a lesser-known sauropod discovered in England.
It walked on two legs, had a brain the size of a banana, and had enormous jaws with 8-inch long serrated teeth in a 6-foot long skull. It is the most popular dinosaur in jurassic world evolution.
5. Utahraptor
At top speed, these extinct animals could probably run up to 20 miles per hour for about 5-10 seconds.
Utahraptor is a genus of large dromaeosaurid theropod dinosaur that lived in North America during the Early Cretaceous period.
6. Allosaurus
This biggest extinct animal was a large bipedal predator. Its skull was large and equipped with dozens of sharp, serrated teeth which means megadolon. It averaged 9.5 meters in length, though fragmentary remains suggest it could have reached over 12 m. Relative to the large and powerful hindlimbs, its three-fingered forelimbs were small, and the body was balanced by a long and heavily muscled tail.
7. Mapusaurus
Mapusaurus was a large theropod and was roughly similar in size to its close relative Giganotosaurus, with the largest known individuals estimated as about 10.2 meters in length or more and weighing about 3 metric tons. Mapusaurus appears to be slightly bigger than Giganotosaurus, a close relative. One of its shin bones is longer, but also a little thinner, which is why Dr. Currie and his colleagues are careful to say they may have found the biggest meat-eating dinosaur on record.
8. Diplodocus
Diplodocus is one of the largest dinosaurs thus far discovered. Diplodocus carnegii, a Diplodocus species, is one of the longest dinosaurs conserved from a complete skeleton, but other individuals likely grew to even larger sizes. Its size and shape is so unusual that paleontologists aren’t even sure how sauropods were able to breathe. This is the most innocent dinosaur in jurassic world.
9. Brachiosaurus
Brachiosaurus is another sauropod, like the Diplodocus. In 1903, paleontologist Elmer S. Riggs named the dinosaur Brachiosaurus altithorax with the name Brachiosaurus being Greek for “arm lizard”, and altithorax being Greek for “deep chest”. The Brachiosaurus also had a bird-like breathing system, with air sacs pumping air.
10. Coelophysis bauri
Don’t let the size fool you. Even though Coeplophysis was only around 44 pounds, fossil evidence shows they hunted in packs. They were also quite agile and boasted blade-like cutting teeth. Coelophysis was a bipedal, carnivorous, theropod dinosaur that was a fast and agile runner.
