Terrifying Prehistoric Animals You are Glad are Extinct

Ultimate Fact Presents Top 20 Terrifying Prehistoric Animals You are Glad are Extinct. Dinosaurs might get most of the glory in museums and on screen, however “when dinosaurs roamed the Earth” is still a bit of a blip compared to the entire time the planet has been around. There are more gigantic, toothy, and winged creatures that existed way back when that are straight-up terrifying. Here are top 20 prehistoric animals you are glad are extinct.
1. Kronosaurus
Body-length estimates, largely based on the 1959 Harvard reconstruction, had previously put the total length of Kronosaurus at 12.8 meters. However, more recent studies, comparing fossil specimens of Kronosaurus to other pliosaurs suggests that the Harvard reconstruction may have included too many vertebrae, exaggerating the previous estimate, with the true length probably only 9 to 10.9 meters.
2. Liopleurodon
Despite needing to breathe air, Liopleurodon spent its entire life at sea and was unable to leave the water. Consequently, it would have given birth to its young alive and may have visited shallower water to breed. Until recently the longest confirmed adult specimen was 18 meters. Some paleontologists believe that it was rather swift in the water and could possibly swim as fast as a shark – which is about 25 miles per hour.
3. Gorgonopsid
Gorgonopsid is the most dangerous extinct animal clade of non-mammalian synapsids from the Permian period. Gorgonopsians were quadrupedal predators with prominent canine teeth, and the largest species were the apex predators of their ecosystems. Like other non-mammalian synapsids, gorgonopsians were once described as "mammal-like reptiles", due to their mix of mammalian and reptilian traits. This look alike dinosaur but monster animal are really scary that anyone should be glad of its extinction.
4. Entelodon
This look alike dinosaur but giant wildlife species was a fairly typical entelodont, with a large, bulky body, slender legs, and a long snout. Like other entelodonts, Entelodon had complete eutherian dentition. It had only two toes on each foot, and its legs were built for fast running. Its long, wide head was supported by a robust, short neck and its cheekbones were greatly enlarged and protruded noticeably from the sides of the head.
5. Epicyon
Before dire and gray wolves roamed North America, an even bigger member of the canine family the biggest member ever, in fact was here. Epicyon lived between 12 and 6 million years ago, and was the size of a grizzly bear, weighing as much as 300 pounds, according to the Florida Museum. That’s like two Newfoundland dogs or three Great Danes, that’s one amazing fact. Definitely this name should be included in the prehistoric park if there were any.
6. Dire wolf
Another big predator that’s commonly found in the La Brea Tar Pits, this wolf species was about the same length as the modern gray wolf, but it weighed quite a bit more—as much as 175 pounds. “Dire wolves had stronger jaws than today’s gray wolves, which meant that they were good at crushing bone,” says Lindsey.
7. Andrewsarchus
This prehistoric animal was a large mammal that lived in the Paleogene period. It was an early artiodactyl hoofed animal, related to hippos and whales. One interesting fact is Andrewsarchus was discovered in Mongolia by naturalist Roy Chapman Andrews, after whom the genus was subsequently named. Andrewsarchus was a large-snouted predator, and, based on skull measurements, may have been the largest ever carnivorous mammal that lived on the earth.
8. Smilodon
Together, they have become known as ‘saber-toothed cats’. The best-known is the Smilodon, which is also known as the ‘saber-toothed tiger’. Three species of Smilodon have been discovered. The biggest, Smilodon populator, was bigger than a tiger, and may have been the biggest cat species ever. Smilodons lived during the Pleistocene epoch, and were found in both North and South America. What a relief that they don’t exist anymore! Scary animal indeed!
9. Woolly mammoth
No list of prehistoric animals would be complete without the woolly mammoth! Mammoths were prehistoric members of the elephant family. They lived during the Pliocene and Pleistocene epochs. The woolly mammoth, is a species of mammoth that lived towards the end of this period. A similar size to African elephant, the woolly mammoth was covered in fur – an adaption for living during the ice age. Are you happy with their extension? What happen if they still alive today?
