Extinct animals and the reason for their extinction

The world loses many animals and creatures over time, as the major extinction events are not something new on the planet, but rather it is natural, but it needs more attention towards the endangered creatures to protect and preserve them. During the past 540 million years, there have been many mass extinctions, in which more than three-quarters of the number of a single species of organism dies within a short period of time. Now, experts are concerned about the mass extinction that is caused by the danger inherent in the loss of these organisms. We bring you a group of recently extinct animals that have left our world over the past decade:

1.Tyrannosaurus Rex

65 million years ago it became extinct
The Tyrannosaurus Rex was the largest carnivore of all time, with a length of 43.3 feet, and a height of 16.6 feet, with a weight estimated to rise to 7 tons. The Tyrannosaurus Rex was a carnivore with two legs with a huge balanced skull, and a long, dense tail. Dinosaur rex fossils are found in the rock formations of North America dating back to the last three million years of the Cretaceous period at the end of the laid-back period, with approximately 68.5 to 65.5 million years old.

Reasons for its extinction

The scientific reasons behind the extinction of dinosaurs may not have been found on the surface of the globe, but according to the journal Science, the extinction of the dinosaurs is due to the crash and collision of an asteroid on the globe.

2.Quagga: half zebra, half horse

It has become extinct since 1883. Kwaga was one of the most famous extinct animals in Africa, it is a subspecies of zebras living in the plains, which is found in large numbers in the Cape Province in South Africa and the southern part of the Free Orange State. This was distinguished from other zebras by the presence of usual live signs on the front part of the body only. Quagas are classified as individual species.

The causes of extinction

The causes of Quaga’s extinction are due to natural variables and overfishing for meat and leather.

3.Tasmanian Tiger – Thylacine

Extinct since 1936
The Tasmanian tiger was one of the largest marsupials known in the modern carnivore. The Tasmanian tiger was present in Australia and New Guinea, and is believed to have gone extinct in the 20th century.

Reasons for its extinction

The Tasmanian tiger became extinct before European settlement on the continent many years ago, but it survived landing on the island of Tasmania along with a number of other endemic species. The Tasmanian tiger has been blamed for intense hunting, in addition to other contributing factors such as disease, the introduction of dogs, and human encroachments into their environment.

4.Javan Tiger

He declared its extinction in 2003
The Yawan tiger had a small size that resembled a large cat, but not the same as the size of other species of tigers. The average male weight was around 220-310 lbs, and the average female weight was around 170-250 lbs. One of the smallest predators of small size in Java, Indonesia.

The cause of extinction

The reason for the extinction of the Yawan tiger due to overfishing, the loss of forest habitats and the lack of prey, causing the number of Yawan tigers to dwindle, and then the Yawan Tigers extinction was officially announced in 2003, to be included in the growing list of extinct species recently.

5.Western Black Rhinoceros

He declared its extinction in 2013
The northern white rhinoceros is from prehistoric times and is the second largest wild mammal, and the second largest mammal in size after elephants. In 2013, the northern white rhinoceros were declared extinct, after their numbers shrank and only four of this subspecies of rhinos, who were at risk, remained.
Despite the size of the Western Big Rhino Lions, they were speed hovers as they could reach speeds of 40 miles an hour when they needed to scare animals or humans. However, these big players had different tactical methods to intimidate, in fact they were very gentle and tough vegetarians. These giants had dark black skin, but they were also very soft to touch and sensitive to sunlight.

The cause of extinction

Habitat loss and overfishing resulted in the fall of the northern white rhino. They had two priceless horns on the black market because of its beauty, in addition to its medicinal value. The northern white rhinoceros was a known animal in Cameroon and West Africa.

6.One of the biggest lions ever – Cave Lion

It became extinct in 2000
The Lion Cave is one of the extinct lion dynasties, and it was one of the largest known lion breeds. An adult male was found in 1985 near Siegsdorf (Germany), the shoulder height is about 1.2 meters and 2.1 meters long without a tail. It appears to have gone extinct about 10,000 years ago, during the Ice Age, while there are some indications that it has been present in the Balkans since 2000.

7.Southern Gastric Brooding Frog

He declared its extinction in 2002
Southern Gastrointestinal Frog or Gastric-Brooding Frog. This animal faced the problem of stomach ulcers, and scientists believed that the ability to stop the production of stomach acid could be beneficial to humans, but it became extinct before scientists could discover a treatment for it.
Southern infectious frog was a species of aquatic species that lives in rainforests, wetland communities and freshwater streams in Australia, in addition to the presence of this species in the wild since 1981, until it was officially declared extinct in 2002.

The cause of extinction

The cause of the extinction of this species has not yet been established. Its extinction may be caused by habitat changes through logging and the presence of non-native species of plants and animals, through disease or something else.
