The world is big, and it's all strange. The earth was born billions of years ago, and with the passage of time, many species have appeared on the earth, many species have died before the birth of humans, and some have survived on the earth for hundreds of millions of years and have not yet perished. The following Xiaobian will introduce you to several ancient and mysterious creatures!
The first, horseshoe crabs.
The ancestor of horseshoe crabs appeared in the geological history period Paleozoic Devonian, when dinosaurs had not yet risen, primitive fish had just appeared, and over time, animals of its contemporaries either evolved or became extinct, and only horseshoe crabs from more than 400 million years ago still retain their original and ancient appearance, so horseshoe crabs are known as "living fossils".
The second, the lamprey.
The lamprey, a prehistoric creature that appeared 200 million years before dinosaurs, has a snake-like shape and a tunnel-shaped mouth with numerous barbed teeth. The lamprey, also known as the eight-eyed eel and the seven-star eel, is an ancient fish of the order Cephalomycerey, distributed in the waters of the Arctic Ocean. Europe's high society has regarded it as a delicacy since the Middle Ages.
The third type, the three-eyed dinosaur shrimp.
Three-eyed dinosaur shrimp first appeared in the Paleozoic Carboniferous period 300 million years ago, after experiencing three earth century mass extinctions, still living in all waters of the earth, three-eyed dinosaur shrimp through the age of dinosaur extinction, ice age, Triassic and other eras, is a very ancient creature!
The fourth species, the wrinkled shark
The wrinkled gill shark has survived on Earth for nearly 150 million years and is one of the top ten living prehistoric animals. The wrinkled shark, also known as the quasi-eel mackerel, is the most primitive type of shark, without subspecies differentiation, and is known as a "living fossil". The gill spacing is long and folded and covers each other, hence the name wrinkled shark.
The fifth, the Komodo dragon
The scientific name Komodo dragon, is the largest known species of lizard, its ancestors have lived in Asia 40 million years ago, and once ruled the Asian continent for tens of millions of years, in the process of continuous evolution its body size gradually shrinks, but adult individuals are also more than 3 meters long, now mainly distributed in parts of Indonesia.
