Species extinction is a part of the natural cycle. Although it is not clear how many species there are in the history of Earth, it is generally estimated that about 4 billion species have evolved on Earth. Of the total number of species that once existed, the vast majority have become extinct. There are countless fascinating animals that will surely amaze you if they are alive today, some of them even live on Earth at the same time as early humans!
This article will travel through time and take you to see seven animals that were extinct in ancient history.
1 Dire Wolf Dire Wolf
Dire Wolf is not just a legend, they are real animals that live in the late Pleistocene and early Holocene. Although diva is known for being much larger than modern wolf, the fossils found vary in size. The last dire wolf is believed to have become extinct more than 10,000 years ago, and was extinct in the late recent Ice Age with hairy elephants and saber-toothed tiger .
Recent research results show that these predators are not actually wolves, but evolved from a common ancestor. Until a few years ago, the dire wolf was part of the Canis genus , which included wolf, coyote and modern dogs. However, the DNA sample collected from the preserved remains of the dire wolf shows that the dire wolf actually belongs to its own lineage, the genus Aenocyon, meaning it is not a wolf at all.
2 Giant Beaver Giant Beaver
These ancient giant beavers are also called Castoroides. They are more than 2 meters long, which is twice the size of their existing close relatives. They have huge front teeth and powerful jaws that allow them to chew trees and branches, as well as large claws used to dig holes in the ground. Native to North America, the giant beaver weighs 200 pounds and is one of the largest rodents ever.
Giant beaver became extinct more than 10,000 years ago. Although the exact date and cause of extinction are unknown, this beaver disappeared shortly after the Pleistocene or during the transition from the Pleistocene to the Holocene.
3 Dwarf Elephant Dwarf Elephant 6
As the name suggests, dwarf elephant is one of the smallest elephants in the world. The dwarf elephant was first discovered on the small island of Tilos in , Greece. Dwarf elephants provide an example of island dwarfism, a phenomenon that a species shrinks over time as a way of survival. The smaller size allows it to save more energy to accommodate scarce resources. The dwarf elephant is believed to be the last elephant living in Europe, extinct about 4,000 years ago, and occurred approximately simultaneously with the development of the first written language.
dwarf elephants actually lived for most of the ancient human history and most of the Holocene. The remains of dwarf elephants found next to the Neolithic tools point to the possibility of coexistence between the two. However, it is not yet certain whether early humans have actually been exposed to these elephants.
4 Hairy Elephant Woolly Mammoth
Hairy Elephant is probably one of the most famous animals on this list, it is a Elephant family mammal that lived in the Pleistocene era. The wool elephant is known for its huge ivory and furry fur. Their rough hair consists of two layers, which is the necessary adaptation for the wool elephants to keep warm during the low temperatures of the late Pleistocene glacial period. They are also amazingly large and weigh about 6 tons.
Historically, humans believed that the extinction of hairy elephants was due to early hunter-gatherers. However, recent research has challenged this theory based on the fact that the original tools our ancestors used were not strong enough to penetrate their thick skin.
Other theories believe that climate change during the interglacial period is the main reason for their extinction. In any case, species extinction is often the result of the combined action of multiple factors over time, and wool elephant is no exception.
5 Saber-Tooth Cat Saber-Tooth Cat
Another famous animal in ancient times was a top predator , living in various continents including North America, South America, Asia, Europe and Africa.In fact, they are top predators, which means they have nothing to fear, and besides the limitations of climate, they can live in any region, which is why they live on so many continents.
These large cat fossils date back to 56 million years ago, in the middle and late Eocene. Their signature feature is long, pointed canine teeth that protrude under their chin, which gives them an iconic name. These cats are also large in size, and some species of saber-toothed cats can grow to nearly 8 feet. The closest relative to the Sabertooth Cat is Cloud Leopard .
6 Cycloid Glyptodon
Cycloid is an extinct mammal genus that lives in parts of South America and North America between 5 million and 11,000 years ago. Related to modern armadillo , the bone plates that cover them provide them with sufficient protection. However, the celestial beasts have some notable traits that make them unique.
is their size first. The celestialis can grow to nearly 3 meters long, 1.5 meters high, and weigh 4,000 pounds, although some subspecies of the celestialis are slightly smaller than this. Larger celestial beasts usually have wider jaws, because they require a lot of food or consume a wider range of food to meet the larger body’s energy needs. Some celestial beasts have hard bones on their tails. Their tails' main uses may be in territorial or mating disputes, as well as against predators.
Cortois are highly specialized mammals with the ability to survive in their environment, but unfortunately, they became extinct more than 10,000 years ago.
7 Big Ground Lazy Megatherium
Ground Lazy is a huge Slot . The word megatherium comes from the Greek words "mega" (meaning "great") and "therion" (meaning "beast" or "animal"). As early as 400,000 years ago, these giant sloths lived mainly in South America and Central America .
They are closely related to modern sloths, but these sloths spend most of their time walking on the ground. Because they are tall when standing with their hind legs - nearly 4 meters long - they wander in woodland or grassland, eating plants and fruits from trees. This means they don't have to worry about climbing trees, as climbing trees is a difficult feat for animals weighing around 8,000 pounds.
However, the strong limbs of earth laziness make it move relatively easily and pull itself up. This giant mammal also has a strong jaw, which some believe may allow sloths to fit into an omnivorous diet. Like many species on this list, Earthlaid became extinct about 10,000 years ago.
Late Pleistocene to early Holocene was a fascinating period full of magical and evil beasts. Species extinction is usually caused by a variety of factors, but the transition from glacial to interglacial periods during this period is likely to be the main cause of these species’ extinction.
Since our ancestors lived on Earth with these animals, human participation may also be a factor, but it is difficult for us to determine. While it would be amazing to see these giant animals, scientists know enough about them that we can imagine what it would be like to walk side by side with these incredible animals.
