Introduction: Not only are there some strange creatures living today, but there are also some ancient creatures in prehistory that look particularly terrible, from dinosaurs to various other reptiles and fish, of which the ten most extinct terrible paleonties are diplodocus, dinosaurs, yaolong, pectoral sharks, Dunn's fish, dinosaurs, night-winged dragons, Sharov dragons, long-necked dragons, sickle dragons, before Xiaobian explained the world's top ten harmless prehistoric creatures, want to know more with the exploration of the book to look down together!
1. Diplodocus
So far, this fossil is the strangest. It is 5 feet tall, and if the entire fossil is intact, it is estimated to be 8.8 feet tall. They ranged in length from 131 feet to 196 feet, making it the longest creature to date, but, the fossils disappeared, misunderstood? Or is it really the biggest animal in the world? Sadly, we may never know.
2. Dinosaur
The only fossil of this dinosaur is a pair of arms that look like they belong to bird animals, but they are 8 feet long. Its use of claws is controversial: some say it was used to tear large dinosaurs apart, while others say the claws were too blunt, so they were used as defensive weapons. Some even say that the dinosaur climbed trees with its giant arms, although few agree with this assumption.
3. Yao Long
This bird-like dinosaur reveals an interesting part of the evolutionary history of birds, without flying feathers, but it does have four long-tailed feathers that were most likely used for display. It lived about 152 to 168 million years ago, and it was also one of the smallest dinosaurs, only 10 inches tall when it reached adulthood.
4. Pectoral and ridge sharks
Sharks have lived for more than 400 million years, and while they remain relatively unchanged throughout the fossil record, there are certainly some strange features, with an anvil-like dorsal fin with small spines on it that can be used for courtship or defense.
5. Dun's fish
This Devonian fish is one of the most fearsome creatures ever lived in the ocean, it can grow up to 33 feet long, has an armored face, and is likely one of the strongest animal bites in history! If you want to know more, please take a closer look at the ten truths of the ancient ocean overlord Tang's fish.
6. Fear
Not only are these elephants large, but they also have a pair of teething jaws. These strange tusks may have been used to dig up soil for tree roots and vegetables, and their torsos are also relatively short, with their heights between 12-15 feet, making them one of the largest mammals ever walking on Earth.
7. Night-pterosaur
The only one without claws on its wings, the species has a giant antler-like peak that some speculate could be used like a sail to enhance its ability to fly. However, research suggests that such a large peak actually affects its flight, so it is likely that it just has a strange set of horns.
8. Sharovron
A gliding reptile with two "wings" on the hind legs and two small "wings" on the front legs. Some scientists believe it is related to plesiosaurs, but it is suspicious that it turned its wings upside down on its legs rather than its arms.
9. Long-necked dragon
This reptile is 20 feet long, but has a 10-foot-long neck! Evidence suggests that it is a fish-eating reptile because its fossils are found mainly at some aquatic fossil sites, with fish scales and cephalopod tentacles found in their stomachs.
10. Sickle Dragon
