Looking at them, some people may say that we Mother Nature must have been drunk in ancient times. From synthetic beasts to species that look like alien creatures, here are the top ten strange animals of prehistory.
Ten odd shrimp

Before the appearance of tyrannosaurs and megalodon sharks, the odd shrimp was the world's top predator, the meaning of the name of the strange shrimp is perverted frightened, it can reach 2 meters long, that is, 6.5 feet, in that period can be regarded as a behemoth. There is also an even stranger species of the odd shrimp, called Tamisiocaris, which has a filter feeding device like modern baleen whales.
Nine Thunder Beasts
The Thunder Beast is a giant creature that looks a bit like a synthetic beast of man, bear and horse, with long and powerful claws on its forearms, which can strip leaves from trees and perform other foraging activities.
Eight pectoral ridge sharks
The pectoral ridge shark is an ancient shark that lived 360 million years ago, and its petite size is named after its anvil-shaped dorsal fin. Its dorsal fin is covered with strange protrusions and its head is covered with small spines, the purpose of which is still unknown.
Seven shovel-toothed elephants
The shovel-toothed elephant looks like a hybrid of a male elephant and a platypus, with two raised giant teeth on its lower jaw. This strange animal lived fifteen to four million years ago because of its shovel-like tusks, and their giant tusks were often used to shovel the ground and cut down branches.
Six Dickenson jellyfish
The Dickinson jellyfish is one of the first known multicellular complex organisms to live half a billion and fifty million years ago, and this mysterious creature is classified as a member of the animal kingdom. Many consider it to be part of the "Extinction Kingdom.".
Five Night Pterodactyls
There is no doubt that the Night Pterodactyl is one of the most bizarre species that has ever soared above the firmament, a pterosaur with a head and a huge bone branch. Many suspect that a thin film was attached to the crown of the night pterosaur, which acted like a sail in front of the ship's front mast.
Four Spiny tooth sharks
The spintooth shark is a shark-like fish with a weird jaw that has plagued scientists for centuries, and the teeth on its lower jaw grow on a swirling structure that looks like a spiral chainsaw, but recent studies have shown that its teeth are actually more like a circular saw growing in its mouth, and the circular saw rotates to dismember the prey when the jaw is closed.
Three grotesque worms
The creature got its name from its weird and dreamy shape, and many aspects of it are puzzling to scientists. This strange creature that lived half a billion and five million years ago has 7 or 8 pairs of legs with claws, and each grotesque worm has a spike on the upper part of its back with an unknown function, and until now people have not been able to distinguish the head and tail of the grotesque worm.
II Charloviron
Saroviron was a special early gliding reptile that lived two hundred and twenty million years ago, with special hindwings behind their extremely long hindlimbs and tiny gliding wings on their forelimbs, which puzzled paleontologists as to how they could both fly and walk.
An Obavin sea scorpion
If an alien creature has ever visited Earth, it must have been the Oberbing Sea Scorpion. Its body has surrealist features, such as its five eyes and clawed tentacles. The Obapien Sea Scorpion's appearance was so bizarre that it became a laughing stock for the audience when it debuted on display. Its strange appendage is thought to be used to feed on the mouth that grows upside down under the head.
