Top 10 Extinct Animals: Natural events such as climatic heat or cooling or changes in sea level can be the cause of the extinction of animals. But in more recent eras, human activity was the culprit.
The main causes of the current extinction, along with pollution, introduction of foreign species and overfishing or overhunting, are habitat destruction as farmland is expanded and forests are cleared. But it is increasingly believed that extinction is caused by climate change.
Based on the estimate that between 200 and 2,000 species become extinct each year, between 0.01 and 0.1% of all species will become extinct each year.
However, UN experts recently discovered that, according to the Convention on Biological Diversity, up to 150 species could become extinct every day. This can be 10% of the species every ten years.
According to a recent estimate by scientists, there are about 8.7 million species on Earth. One to two million of those species are thought to be animal species. However, we’ve probably only covered about a fifth of everything in the time humans have discovered and documented new species.
The following list contains 10 amazing extinct animals. Read on to find out what happened.

Top 10 Extinct Animals
|1||Plesiosaurus||Cretaceous (66 million years ago)|
|2||woolly mammoth||1650 BC|
|3||saber-toothed cat||8,000 BC|
|5||Steller’s Sea Cow||1768|
Without the mysterious Plesiosaurus, a huge aquatic reptile that roamed the world’s waters during the Jurassic and Cretaceous periods, the list of the top 10 extinct animals would not be complete.
Plesiosaurs come in several species, but the ones with the longest necks and smallest heads are the most famous. Most of these animals were astonishingly large, occasionally growing to a whopping length of 65 feet.
The Loch Ness Monster, a legendary creature that some claim to inhabit the waters of Loch Ness in Scotland, is a subject of intense belief among many people. Some people even think that the existence of the Loch Ness Monster is evidence of a plesiosaur that is still alive today.
However, according to the fossil record, plesiosaurs would have disappeared around the end of the Cretaceous, about 65 million years ago. And despite the fact that both groups existed and died at the same time, they weren’t dinosaurs, despite what the general public thinks.
2. Woolly Mammoth – 1650 BC.
Another extinct animal in the world is the woolly mammoth, this huge, furry creature with long ivory tusks curling out of its giant trunk-like nose must be the creature best associated with the Ice Age.
Several species of mammoths, including the woolly mammoth, the oldest of which were probably small aquatic mammals that lived in North Africa until about three million years ago.
One of the smaller mammoths, the woolly mammoth, made its way across the Beringland Bridge to North America sometime in the late Pleistocene, and its descendants then spread across Eurasia.
Unfortunately, this mysterious monster did not last long in the New World. About ten thousand years ago, towards the end of the last ice age, the last woolly mammoths died.
3. Saber-toothed cat – 8,000 BC.
On the list of the top 10 extinct animals, the saber-toothed cat went extinct in the year 8,000 BC. They were about 55 million to 11,700 years ago and were often referred to as saber-toothed tigers or saber-toothed lions.
The carnivorous saber-toothed cats get their name from their long, leaf-like canine teeth, which can reach 50 cm in certain species. They had a very bear-like build and were considered excellent hunters, taking down prey such as sloths and mammoths.
These cats had jaws that could expand at a 120-degree angle, which is almost twice as wide as a lion today! It is thought that the decline and extinction of the large herbivores that the saber-toothed cat hunted may have contributed to their extinction. Competition with humans and climate change are two other factors.
4. The Dodo-1662
The Dodo, an extinct wingless bird that lived in Mauritius, was about a meter high and weighed maybe 10-18 kg. The exact appearance of the Dodo is still a mystery, as the only documentation we know of it comes from a variety of written and illustrated stories from the 17th century.
It is believed that the bird lost its ability to fly due to the abundance of food supplies (seeds, roots and falling fruits) and the absence of many predators.
The dodo was originally named by Dutch sailors in 1598. Sailors, their domesticated animals and exotic species hunted the bird to extinction. The last confirmed sighting of a dodo was in 1662.
5. Steller’s Sea Cow-1768
Steller’s Sea Cow is another Top 10 Extinct Animals in the World. The bulky herbivorous animal named after George Steller, a naturalist who found it in 1741. The inhabitants of the Near Islands, southwest of Alaska, and the Commander Islands in the Bering Sea, are thought to have been Steller’s Sea Cows, reaching heights of at least 8 to 9 meters and weights of 8 to 10 tons.
The mammal is thought to have been domesticated and spent much of its time eating kelp; this, along with the possibility that its large body was unable to submerge, may have made it vulnerable to human hunters. The Steller’s Sea Cow was hunted to extinction just 27 years after Europeans first discovered it.
6. Great Auk-1844
A huge wingless bird found in the North Atlantic and as far south as northern Spain. He was on average 75 to 85 cm tall and weighed about 5 kg. The Great Auk had a strong swimming ability, which allowed it to hunt for food underwater.
On the island of Eldey there was a last colony of Alken, but by 1835 they had all perished. Three men caught the last of these birds in St Kilda, Scotland, in 1844, and killed him.
They slaughtered the auk because they thought it was a witch who was responsible for the storm when a significant storm surge occurred.
7. Top 10 Extinct Animals-Quagga-1883
The quagga is a mammal associated with modern-day zebras and horses. It really only has stripes on its head and neck, which disappear as they get closer to the brownish hindquarters of the animal, making it look like a mix between a horse and a zebra.
Before being hunted to extinction in the 1870s, the quagga was a native of the desert regions of South Africa. During the 1880s, all pets kept in Europe died.
The quagga is an extinct animal with a few claims to fame. First, it was the first animal whose DNA was examined, showing that the quagga was actually a subspecies of the plain zebra rather than a separate species.
The project, aptly titled, has also established an extensive breeding program for the quagga, whose offspring was a foal born in 2005. The “recreated” quagga is very similar to the extinct quagga, but DNA testing has only confirmed whether this animal is real.
8. Passenger pigeon-1914
The passenger pigeon is eighth in the Top 10 Extinct Animals. A bird with flocks so large that it would take days for them to travel over their heads, darkening the sky as they passed, astonished early settlers in the New World.
Any farmer unlucky enough to feed passenger pigeons would see his entire crop destroyed in seconds. Then, practically overnight, the most common bird in North America disappeared from the face of the earth.
An illustration of how nature and man are in direct confrontation is the disappearance of the passenger pigeon. When the first Europeans arrived in America, as many as 3 to 5 billion people lived there.
However, the New World did not have enough space for either species. As a result of relentless hunting, deforestation, and other aspects of humanity’s ever-expanding range, passenger pigeons were quickly wiped out. By 1914, the last known bird had already died, and its extinction only became apparent at the beginning of the 20th century.
9. Tasmanian Tiger-1936
The huge carnivorous marsupial known as the Tasmanian tiger was native to Australia, Tasmania and New Guinea.
The animal, which was not related to tigers and looked like a medium to large dog, weighed 30 kilograms and over 2 meters long from nose to tail, but it had dark stripes that made it look like a tiger.
It is thought to have been hunted to extinction, and bounty-based hunting was encouraged. However, illness, introduction of dogs and human encroachment on its habitat are also all possible causes.
Between 1910 and 1920, the last wild Tasmanian tiger was killed, while the last one in captivity died in 1936 at the Hobart Zoo in Tasmania.
10. Baiji Dolphin-2006
Last on the list of the Top 10 Extinct Animals is the White Baiji Dolphin.
Only the Yangtze River in China is home to the Baiji White Dolphin, also known as the Chinese River Dolphin. These creatures could reach a length of two meters and a weight of a quarter of a ton.
Because of their small eyes and extremely weak eyesight, they depended on echolocation to travel and search for prey. After spending 20 million years in the Yangtze, their population declined rapidly from the 1950s onwards.
Using the river for hydroelectricity, transportation, and fishing as China’s industrialization progressed, had a significant impact on mammals. No one has seen a Yangtze river dolphin since 2006, but they are not officially considered extinct.
