1, komodo dragon
No other lizard in the world looks more like a prehistoric animal than Komodo dragon. They originated from the genus monitor lizard and their history can be traced back to about 40 million years ago. Komodo dragons first appeared in Asia and later migrated to Australia. They are the largest and heaviest lizards in the world, with a body length of 3 meters and a weight of 160 kg. Although they were named after Komodo Island in Indonesia, their ancestors first appeared in Australia about 6,543.8 billion years ago.
2. Dune crane
Dune crane is also called brown crane or Canadian crane, and its model origin is Hudson Bay, Canada. Sandhill crane is a large wading bird with a body length of100-10 cm. It is a national second-class protected wild animal in China. The history of sandhill cranes can be traced back to 6.5438+million years ago. There are several subspecies of sandhill cranes living in North America, some of which are listed as endangered species. Sandhill cranes are very popular with bird lovers because they migrate long distances every year. Thousands of sandhill cranes migrated all the way from Mexico and the southern United States to the North Pole.
3. aardvark
The aardvark, also known as the African anteater, is a strong animal, distributed from sub-Saharan East Africa to South Africa. In Africa, it means local pigs that feed on ants and termites. 5 million-year-old aardvark fossils were found in South Africa. The aardvark is a nocturnal burrowing animal and the only existing species in the order aardvark. Eat a lot, you can eat 50 thousand termites a night.
4. red panda
This lovely animal comes from the Himalayas and temperate forests in China, and is the only member of the red panda family. In 2020, scientists discovered two different kinds of red pandas: Himalayan red panda and China red panda. The ancestors of red pandas lived from 5 million to 6.5438+0.2 million years ago. Although they also like to eat bamboo, they are not closely related to giant pandas. In the past 50 years, due to the large-scale reduction of habitats and the influence of human hunting activities, the population of red pandas has decreased by 40%.
5. Beaked lizard
The coracoid lizard is the only surviving reptile of the coracoid and the only representative of the coracoid in the early Triassic. Only found on some small islands in New Zealand. They look like lizards, and their shapes are very similar to those of ancient ancestors who lived and multiplied 200 million years ago. At present, the oldest beaked lizard is over 100 years old, and experts believe that they can live to be over 200 years old under suitable conditions. In 2020, the new car Tuatara named after the beaked lizard by Silbert Super Run Company became the fastest production car in the world.
6. Nautilus
Nautilus is a cephalopod, unlike other distant relatives such as squid and octopus, they keep a shell. For centuries, their beautiful shells have inspired many artists and are one of the best natural examples of logarithmic spiral or golden ratio. It is the existence of shells that makes the fossils of Nautilus easier to find than the remains of other cephalopods. Fossil hunters have discovered ancient nautilus at least 500 million years ago.
7.the purple frog
Purple frogs spend most of the year underground at a depth of 4 meters. Purple frog belongs to a branch of a special frog that lived in the ancient dinosaur period. It was not discovered in India until 2003. Its nose looks like a pig's nose, so it is also called a pig-nosed frog. Although this purple frog was found in India, it belongs to a frog that only exists in Seychelles. Seychelles was separated from India about/kloc-0.0 billion years ago, which means that the purple frog has existed for about 654.38+0.2 billion years.
8. platypus
The platypus is one of the most primitive mammals, and it is a mammal with incomplete evolution. With a mouth like a duck and a body like the hair of a mammal, it is difficult to find an animal more unique than a platypus. Platypus is only distributed in eastern Australia and Tasmania. They have 10 sex chromosomes, not just two like most other mammals. The platypus is one of the most poisonous mammals in the world.
9. Blind eels
The blind eel is an ancient fish, which generally lives below 100 meters above sea level. Blind eel's teeth are like rows of combs, and it is the only parasitic animal among vertebrates. Some taxonomists don't want to regard them as vertebrates because they are the only animals with skulls but no spines. From an evolutionary point of view, they can be traced back to 330 million years ago, representing an important life link between vertebrates and invertebrates.
10, musk pheasant
The classification of these strange-looking and huge pheasants is controversial, and they are related to both cuckoo and chicken. Very good at climbing, the young bird's forelimb has two wing claws, similar to Archaeopteryx and Confucius bird, but it is not the original character, but a special adaptation to climbing life. Because the body gives off a strong musty smell, it is called musk pheasant. Musk pheasant, the national bird of Guyana, lives in the flooded forest in the Amazon basin of South America.
1 1, koala
Koalas, koalas, koalas and koalas are Australia's national treasures, as well as Australia's rare and precious primitive arboreal animals. They can get 90% of the water they need from eating eucalyptus leaves, and only drink water when they are sick and dry. The locals call it "koala", which means "no water". Koalas are not Xiong Ke animals. They are far away from each other. They belong to the marsupial family. Koalas sleep 18 hours a day, with a gentle temperament and a simple and honest posture. Although fossils are very rare, they are likely to have existed for at least 30 to 40 million years.
12, pig-nosed turtle
Pig-nosed turtle, also known as Oceania pig-nosed turtle, is the only species of the genus Trionyx in the family Trionychidae. Only distributed in northern Australia, southern Irian Jaya and southern New Guinea. Unlike most freshwater turtles, their flippers are closer to turtles, so they are almost entirely aquatic animals. Its history can be traced back to about1.400 million years ago. Since it was listed as the world's endangered animal 10 by the World Wide Fund for Nature in 2004, its value has soared and it has been sought after and loved by turtle lovers.
13, limulus
Horseshoe crab is also called horseshoe crab, but it has nothing to do with crabs. They are not even crustaceans, but are more closely related to arachnids such as spiders. The ancestors of horseshoe crabs appeared in the Devonian of Paleozoic, when dinosaurs had not yet risen and primitive fish had just come out. With the passage of time, its contemporaries have either evolved or become extinct. Only horseshoe crabs, which came out more than 400 million years ago, still retain their primitive and ancient appearance. King crab/horseshoe crab
14, Euonymus acutus
European rice leaf roller, also known as European rice leaf roller, European rice leaf roller and European rice leaf roller, is the only species of European rice leaf roller family. They were first discovered in Japanese waters and are thought to be closely related to the extinct sword shark that lived in Cretaceous. Among the more than 400 known shark species, Euonymus is really strange. one
15, elephant shrew
The shrew belongs to the shrew family in insectivora. Although it looks like a mouse, there is no relationship between them. It is the earliest placental animal, produced in Mesozoic Cretaceous, and is the smallest mammal in the world. Elephant shrew is the general name for elephant shrew, with a long and flexible mouth (or kiss). Because all elephant shrews are named after their long trunks, their noses are extremely sensitive to touch and smell.
16, crocodile
No other animal deserves the title of living fossil like crocodile. Since walking on the earth, they have shown the same body shape and survived several mass extinctions. Crocodiles are also close relatives of birds, representing the long-term relationship between birds and reptiles. Their common ancestor existed 240 million years ago. Crocodiles are one of the earliest and most primitive animals discovered so far. At present, there are 23 recognized crocodile species.
