The earth has been born for 4.55 billion years, the stars have shifted, the sea has been changed, and many species have disappeared in the long river of history because they cannot adapt to the environment.
Today we will take a look at 4 kinds of strange-looking prehistoric beasts.
Shovel tooth elephant
The shovel-toothed elephant is a creature that lived in the Miocene era more than 10 million years ago, its appearance is very strange, it has two pairs of tusks, and the lower jaw is extremely elongated, much like a large shovel, with a pair of flat lower incisors on it, so it is named the shovel-toothed elephant.
The jaw of the shovel-toothed elephant is not only a tool for hand use, but also a powerful weapon. Shovel-toothed elephants generally live by lakes, and they can use their shovel teeth to cut off plants and then rely on their noses to send plants to their mouths.
Shoveltooth elephants are found in various parts of Eurasia, and the population is so dense that by 4 million years, the shovel-toothed elephants were all extinct.
Nguma-Manine
Nguma-Manenet is a mysterious creature that lives in the Republic of the Congo, with sharp teeth, a forked tongue and short legs that are good at running, and a special bone plate on its back.
There is an idea that Nguma-Manine was actually the surviving spinosaurus, a creature that could move rapidly through swamps and feed on birds and small animals.
According to a small number of eyewitness reports, Nguma-Manine is about 10 to 40 meters in size. When swimming in the water, Nguma-Manine is easily mistaken for a giant python.
Devil frog
Also known as the devil toad, the devil frog lived in the middle and late Cretaceous period 70 million years ago, with a wide mouth and a strong jaw, weighing an estimated 4 to 5 kilograms, making it the most ferocious frog ever made, and could even eat newborn dinosaurs.
The devil frog's jaw is capable of producing a closed force of 2200 cattle, which is equivalent to the top predator today.
Spiny tooth shark
The spiny tooth shark is also a very strange-looking ancient fish, its name is derived from the Greek language, which together means spiral saw. The teeth of the spiny tooth shark's jaw are rolled into a spiral shape, like a milling cutter, which looks very sharp.
Whether in fish or among vertebrates, no animals with such teeth have been found except for the spiny tooth shark.
The spiny tooth shark lived in the Permian and Triassic periods, 200 million to 300 million years ago, and can reach a body length of up to 15 meters.
The use of the spiral jaw of the spiny tooth shark is still controversial, with some believing that this spiral structure can be used to impact prey and resist predators, while others believe that this structure helps the spin tooth shark to see through the shell of its prey.
