Beijing time on December 2, according tomedia reports, according to incomplete statistics, 99% of the earth’s species have disappeared, The Intrepid Dragon, a dinosaur that lived 0.77 billion years ago, is by far the largest land creature on Earth; the birds were the largest bird in North America before the overkill; and although the current animal extinction crisis is not obvious, there are many signs that the Planet is in the midst of another animal extinction.
Animal numbers are declining at an alarming rate due to human activities such as deforestation and mining, and a United Nations report has found that the number of endangered species on Earth may be closer to one million today, but that’s nothing compared to the number of species that have disappeared in Earth’s history. Here are 25 interesting facts about extinct animals:
1, 1494, the first human discovery of the Caribbean monk seal, and then a mass hunt to obtain its fat.
The Caribbean monk seal was once the only native seal species in the Caribbean, and in the 18th and 20th centuries, during the reign of European colonists, hunters hunted them down to get their body fat. The species was listed as an endangered species in 1967 and declared extinct in 2008, and no Caribbean monk seal has been found in humans for more than 50 years from 1967 to the present day. Human overkill has made its numbers unsustainable.
2, despite appearing in the sci-fi film Jurassic Park, scientists still believe the prototype is full of feathers.
In the sci-fi film Jurassic Park, the dragons are portrayed as a large, scary dinosaur species that brutally kills prey, but the depictions in the film may be somewhat different from reality. In addition to the python’s size similar to that of a turkey, scientists also believe that the dragon’s body is covered with feathers, and paleontologists have found signs of feathers on its limbs.
3, elephant bird body size, can not fly, weight of more than 450 kg.
About 10,000 years ago, elephant birds walked on Earth, a three-metre-tall bird that may have small wings that are useless for flying, weighing more than 450 kilograms, and its eggs are considered to be the largest of all animals, given its size. Humans hunted and eaten elephant birds, and deforestation led to the loss of elephant bird habitats, causing the elephant population to decline rapidly, eventually disappearing around the 16th century, scientists said.
4, the last gray beach died in discovery island nature reserve.
There were thousands of gray beach on florida’s east coast, and as the bird was dying out under pesticides and construction, conservationists at waltdisney Discovery Island Nature Reserve tried to save the species through hybrid breeding. In 1987, the last gray beach named Orange Belt died in a cage, marking the end of the species.
5. The Fearless Dragon was once the largest land animal on earth.
The Intrepid Dragon, a long-necked dinosaur that lived about 77 million years ago, is thought to be the largest land animal on Earth, weighing 65 tons, 26 meters high and 11 meters long, compared with about 5.5 meters tall in modern giraffes.
6, the Irish moose has the largest antlers.
The Irish moose, a now extinct deer species that once lived in Europe and Asia, has a four-metre-long large antler, the longest of all known deer species, and scientists believe it disappeared after suffering from hunger during the Ice Age.
7, Tecopa can live in 42 degrees Celsius of water environment.
Tecopaist is known for living in Tecopa Hot Springs, California, USA, and is able to adapt to changes in water temperature of 10-42 degrees Celsius due to fluctuations in water temperature. In 1981, the local Fish and Wildlife Service searched more than 40 waters and found no trace of Tekopa, officially declaring the species extinct.
8, a dragon is a “heavy armor” dinosaur, its tail can be used as a stick.
Although the dragon is not the largest or most ferocious dinosaur, but its whole body covered with bone plate, is to resist predators such as the tyrannosaur attack has effective defensive armor, the tail of the dragon has a bone sphere, if it is enraged, it will use the swingtail to launch an attack, scientists pointed out that the tail of the dragon also has the role of attracting mates.
9. Some mammoths are frozen in the ice and their bodies are preserved intact.
Mammoths died out more than 4,000 years ago, but that didn’t stop scientists from bringing samples of mammoth carcasses to the lab, and since mammoths live in what is now Siberia, some of them are frozen after their deaths and kept them intact. Modern sled dogs are said to sometimes eat mammoth meat from 30,000 years ago.
10, the Pyrenees goat was “successfully saved” from the brink of extinction.
After years of human manhunt, the number of Pyrenees goats was endangered in 2000, and thankfully scientists extracted the cell before the species became extinct and planned to clone it, and in 2003 the Pyrenees goat became the first animal to be resurrected from extinction, but died a few minutes after the cloned sheep were born.
11, the life span of the king dragon only 29 years.
Although the Tyrannosaurus rex is the most familiar dinosaur species, They lived in the late Cretaceous period of 0.85-065 million years ago, the activity is mainly concentrated in the present-day North America, so far scientists have found that the largest tyrannosaur situ only survived about 29 years, this is the scientists through the analysis of bone fossils concluded that the tyrannosaur situated 20 years of adult size, meaning that they did not live long.
12. Wildcats are one of the causes of the extinction of Stephens Island.
The smaller, non-flying Stephens Island, which lives on an island off the coast of New Zealand, was wiped out in 1895 by land development and the introduction of cats, and according to folklore, a female cat named “Tibuls” came to Stephens Island with its owner in 1884, the first cat to come to the island, and then the cat bred in large numbers. caused the extinction of Stephens Island.
13, sword dragon back bone plate may be used to regulate body temperature.
The dragon lived during the Jurassic period, about 159-144 million years ago, and its biggest features were a stinging tail and flat back, but a new study has found that the saber-bone plate regulates its body temperature, collecting not only the sun’s heat to maintain its body temperature, but also the release of heat to cool.
14, The Duo Gao Wu-toed gecko extinction more than 100 years “only found.”
Kawekaweau, a brown gecko living in New Zealand, has not been discovered by scientists for its survival, and is said to be 0.6 meters long, but scientists have not found the living Duokohu gecko. The most recent “contact” with the Duo Kowu-toed gecko was in 1870 when a biologist heard how maori leaders described how to kill a Duo kogo toe-toed gecko, and in 1986, researchers found an unmarked sample in the basement of the Natural History Museum in Marseille, France, which was carefully analyzed and identified as the Duo Gao Wu-toed gecko.
15, the Carolina long-tailed parrot is the only native species in the eastern United States.
The parrot, which lived in southern New York, Wisconsin and the Gulf of Mexico, was the last Carolina long-tailed parrot to die at the Cincinnati Zoo in February 1918, but was not officially declared extinct until 1939, experts analyzed the habitat loss, pest control, and human skilled ness of their feathers. eventually led to their path to extinction.
16. The brigade was once the “air ruler” of North America.
In the 19th century, the birds were the largest in North America, accounting for 25-40% of the total number of birds in the United States, often mentioned in the travel logs of early explorers, and it was said that the flock was so large that it took several hours for the entire flock to pass through a certain point. But as a result of human activity, the number of doves gradually declined, and in the early 20th century, Martha was the last known flock erstwhile, and died at the Cincinnati Zoo in 1914, due to overhunting.
17, Charles Darwin accurately predicted the extinction of the Falklands Wolf.
The Falkland Son wolf, also known as the Falkland Sont, may have come to the Falklands at the end of the Ice Age, and in the 200 years since it was discovered, the species was hunted down by humans and eventually wiped out. The species was discovered when Charles Darwin visited the island in the 1830s, and the last Falkland island wolf is believed to have been hunted 40 years later, predicting the extinction of the Falklands Wolf in his book The Naturalist’s Voyage around the World: The Little Hound. “When humans settled in the Falklands for a few years, wolves like the FalklandS and the ferry birds would gradually disappear,” he wrote. “
18, scientists consider resurrecting extinct ferry birds.
The ferry bird, a 50-pound bird that lives on the island of Mauritius in the Indian Ocean, was a major cause of extinction by Dutch sailors and colonists, as well as alien creatures (rats, pigs and cats) brought by the colonists. Although scientists declared the bird extinct in 1681, modern scientists sequenced the genome of the ferry bird, increasing the likelihood of its resurrection, but resurrecting extinct organisms was not an easy thing to do, and many experts did not support it.
19. The swollen dragon has a domed skull, formed by the growth of a large bone.
At the end of the Jurassic period, 065 million years ago, the python lived in what is now North America, its shape is very unique, with a large bone on its head that covers the tissue that protects the brain, and palaeontologists initially speculated that the domed skull was a “impact weapon” in the event of a fight, but now they believe the structure is “identification”. “。
20, efforts to protect the puffin led to its extinction.
The original habitat of the puffinis is the North Atlantic region, a black-and-white flying bird, similar to penguins, whose fat, eggs and feathers are sold as commodities due to human overhunting that led to the extinction of the species. In the early 19th century, when the species’s numbers began to plummet, attempts were made to raise awareness of the species by displaying skin samples in museums, but this led to the eventual extinction of puffins, the last pair of puffins killed by a fisherman in 1844. The fisherman’s hunt was designed to sell the pair’s bodies to museum collectors.
21. The extinction of the Stryre manatees led scientists to believe that extinction was possible.
The Ssterman, weighing nearly 10 tons and 9 meters in length, is a close relative of modern manatees and dugongs, and in the 18th century many naturalists thought the species was unlikely to become extinct, and hunters continued to hunt manatees and feed on manatees, believing that Sstermana would continue to breed. The last Stryre manatee was discovered in 1768, and scientists have not found the species since then, leading European scientists to believe they are extinct.
22. There is evidence that Ma Junlong is a similar food eater.
Majungasaurus, a large dinosaur that lived in the area of present-day Madagascar, has short, sharp teeth that make it easy to bite and kill prey. A paper published in the journal Nature entitled “Madagascar dinosaurs swallowing similar behavior” said that the bones of the Majun dragon left traces of similar teeth, which is reliable evidence of their existence of similar eclipses, and evidence that similar eclipses are a feeding strategy of the dinosaur species, scientists have rarely found evidence that dinosaurs swallowed the same kind.
23, the saber-toothed tiger jaw open can form 90 degrees.
The saber-toothed tiger lived 50 million years ago and is spread across present-day Europe, Asia, Africa, North and South America, and is very close to modern African lions. Sword-toothed tigers have many features in their bodies that help them hunt their prey, and their jaws can form 90 degrees when they open, combined with their powerful tearing power, enough to make a fatal blow to their prey.
24, scientists tried to revive the black chicken.
The hecin chicken, which lived extensively in New England, was hunted to near extinction in the 1870s, with only a small number living in the Martha’s Vineyard region, and in 1932, scientists declared that the hecin chicken was extinct. Since 2013, a team of researchers has tried to revive the black chicken, publishing a paper detailing why the species has unique genetic value.
25, the sickle dragon is a strange-looking dinosaur, with terrible claws.
120 million years ago, the sickle dragon lived in what is now Asia and North America, and paleontologists speculated that it weighed 6 tons and was similar in size to the tyrannosaur, but because of its smaller skull and teeth like blades, they were more likely to eat plants than meat. The sickle dragon belongs to the animal-footed dinosaur group, which has longer forelimbs, but the forelimbs of the sickle dragon, waving like a sickle, they are very good at fighting. (Ye Ding Cheng)
