Top 13 Extinct Animals | Extinction Over Time

You probably already know that there were once animals on the Earth that don't live here anymore - like dinosaurs, or the wooly mammoth. We say that animals that have died out - that is, all of them have died, so none are left alive - have gone extinct. 

Most people think of extinct animals as ones that died out a long, long time ago, but some animals have gone extinct recently enough that people saw it happen and in some cases, even caused it there are just so many of them we could probably give them a list all their own.


Here are one of the 10 Extinct animals. Let's See.


1. Saber-Toothed Tiger or Saber-Toothed Cats.

 Saber-Toothed Tigers or rather Saber-Toothed Cats are among the most famous extinct animals in the world just think of the famous ice age cartoon where the saber-tooth tiger Diego is one of the main characters the last saber-toothed tigers became extinct about 10 to 11,000 years ago.

Scientists believe that the saber-tooth tigers were the first animals on the planet that have gone completely extinct because of humans however mankind can still get a chance to apologize to these creatures by reviving them scientists believe that the remains of saber-toothed tigers preserved in the permafrost can serve as sources of DNA.

If scientists can manage to get the saber-tooth tiger genes they will have to find a surrogate mother later on according to the researchers the best candidate is the african lioness which is believed to be the optimal egg donor.


2. The Siberian Unicorn

Don't let your imagination run too wild this animal was more like a rhino than a gracious horse at first scientists believe that this creature died out 350 thousand years ago but a siberian unicorn skull discovered in Kazakhstan proved that the animal had actually disappeared just 29,000 years ago. 

It did have one big horn coming out of its skull the siberian unicorn was 15 feet long six feet tall and its weight reached a whopping 9,000 pounds there you go folks that's what a real unicorn looks like.



3. Dodo

The dodo is an extinct flightless bird that was endemic to the island of mauritius in the indian ocean along with mammoths and dinosaurs the dodo is one of the best known extinct species and the most famous extinct bird in the world unfortunately humans were the reason the dodo went extinct before people began to populate mauritius the dodo lived carelessly in isolation from any predators. 

While people on the other hand realized how defenseless the dodos were and used them for their own benefit throughout the 17th century people destroyed these birds natural habitat while the animals that people brought with them ravaged the bird's nest and competed with them for the limited food resources as a result the dodo population declined sharply and the last mauritian dodo died in 1662 we think that these amazing birds were treated unfairly.


4. Aurochs

Aurochs is an extinct ungulate mammal that was domesticated by the ancient settlers of India and eurasia about 10,000 years ago aurochs is considered to be one of the ancestors of all modern cattle but unfortunately this historically important species was declared extinct in the 17th century A.D.

When the last aurochs died of disease scientists are currently planning on resurrecting the aurochs by back breeding the primitive breeds of european cattle they plan to breed species similar to the aurochs until they get an animal that's as similar as the aurochs.


5. Fabled Ivory-Billed Woodpecker

The fabled ivory-billed woodpecker is recently recognized as completely extinct it's officially listed as a species that is in danger of extinction. The loss of the species was hailed by many as a consequence of human population growth and the attendant loss of natural habitats and growth in pollution, as well as the climate crisis.



6. Mammoth

Mammoth as these mammals are perhaps the most famous extinct creatures in the whole world. This is largely due to the fact that mammoths receive a lot of attention in pop culture there have been many movies and cartoons made about them such as the ice age for example featuring many that's why many people are waiting for the resurrection of mammoths they'd be very interested in seeing how these animals actually looked apparently these wishes might come true soon since scientists often find remains of mammoths in the permafrost just recently.


A mammoth that lived only 4,300 years ago was found on wrangle island in the arctic ocean scientists believe that resurrecting mammoths is easier than other extinct animals because the permafrost prevents them from completely decomposing and preserving important genetic material scientists have already extracted cells from the remains of many mammoths and plan on combining the mammoth genes with the genome of an elephant embryo to create a hybrid of a mammoth and an elephant with all the mammoth traits that we know from movies and books.


6. The Ground Sloths

The ground sloth what once was a unique beast that thrived during the Ice Age periods is now known for associating with a dim-witted animated film character upon their extinction over 10,000 years ago it's believed to be no coincidence that the deaths of the ground sloth are linked to humanity's entry into the North American regions.

Though climate change was also a factor but in the 1820s one was uncovered here on skidaway Island which was the first one found in the United States with large and dangerous looking claws speculation remains to this day about whether this variation of sloth only used them to collect bark from trees though it's most likely that these mammals were herbivores although slow-moving its massive size was protection against smaller predators like the Saber-Toothed Cat. 


7. Woolly Rhinoceros

Wooly rhinoceros besides the woolly mammoth there's one more fluffy extinct creature the woolly rhinoceros that scientists want to bring back this animal still lived in the arctic snows pretty recently about ten thousand years ago this furry rhino is quite famous too it often makes an appearance in ancient cave arc like in the french chauvet point arc cave the woolly rhinoceros has the same chances of being resurrected as the mammoth arctic permafrost has done a great job at preserving quite a lot of specimens.


8. The Irish Elk

The irish elk also known as the giant elk is an extinct ungulate mammal from the  cervidae family this species existed from the late pleistocene to the beginning of the holocene 10 to 13,000 years ago throughout eurasia and north africa but especially many remains were found in the peatlands of ireland.

Hence the name of the species scientists note that the irish elk was one of the largest deers that ever existed on the planet the height of the largest individuals was over two meters at the withers while the distance between the tips of their horns could reach up to four meters.


9. Steller' Sea Cow

Steller's Sea Cow was a marine mammal, similar to living dugongs and manatees, but much, much larger. First described in 1741 by the German explorer Georg Wilhelm Steller during an expedition in the North Pacific, Steller's Sea Cow grew to a length of 30 feet or over 9 meters. Slow moving herbivores, the sea cows were easy to catch and kill. 

They provided valuable food for the explorers; in addition, their thick skins were used to make boats and their fat was used in oil lamps. Already endangered when Stellar first wrote about them, it took only 27 years for hunters to kill the last of them, and by 1768 they were extinct.


10. The Great Auk


The Great Auk

Although similar to them in appearance, the great auk was actually not at all related to penguins. Native to the North atlantic and found along the coastlines of Canada, Greenland, Iceland, Norway, Ireland and Great Britain, the Great Auk was a tall bird, reaching 33 inches or 85 centimeters in height. Much like penguins, great auks were flightless, but agile swimmers, diving to catch fish and other sea creatures to eat. 

Hunted by humans for their feathers, which were used to stuff pillows, by the mid 1500s their populations were declining. When people realized that they were becoming rare, they attempted to protect them. These measures were at least partially sucessful, because the great auk survived nearly three hundred years from that time before finally becoming extinct around 1844.


11. The Quagga

Long thought to be a distinct species, modern research has shown that the quagga was actually a subspecies of the modern plains zebra. Native to a small area of south africa, the quagga was hunted for its meat and for its unusual skin - striped at the head, and brown near the tail. 

The quagga was extinct in the wild by 1878, although a few solitary animals survived in zoos until the last died in 1883. Because the quagga was so closely related to living zebras, scientists think it might be possible to recreate them with selective breeding. 


12. The Bluebuck

A species of antelope that formerly ranged the southern tip of South Africa, the bluebuck was not actually blue, although it may have seemed that way due to a mixture of black and yellow hairs. When Europeans first encountered the bluebuck in the 17th century, it was already quite rare, and it did not take very many years for the last of them to be hunted down and killed as food, although it is recorded that they did not taste very good. Still, by the year 1800, bluebucks were extinct.


13. Baiji or Chinese River Dolphin

The baiji commonly referred to as the Chinese river dolphin the majestic creature could only be found in the Yangtze River in the Asian country where it got its name affectionately nicknamed the goddess of the Yangtze. The baiji became victim to the growing advances and industrialization of modern china that led to massive water pollution by the end of the 20th century there were possibly only 13 wild dolphins left in the Yangtze repeated efforts were made to conserve the species but an expedition in 2006 failed to discover any remaining baiji in the river.

The last living baiji known as Chi Chi died in 2002 for the international conservation community it really needs to act as a wake-up call that we need to be far more efficient and far more quick to react to conservation crises in the future.



Most people think of extinct animals as ones that died out a long, long time ago, but some animals have gone extinct recently enough that people saw it happen and in some cases, even caused it.
