10 Extinct animals in the last 100 years

We are in the midst of the sixth mass extinction at this time: humans are behind an increase unprecedented in the speed in which we are losing species. Here's a tiny sample of what you have already lost, since the beginning of photography to the present.


The Thylacine, the modern era's largest carnivorous marsupial (measured about 60 centimeters high and one meter 80 long including the tail), lived on the Mainland of New Guinea and Australia in the time when European settlement of these animals was virtually extinct due to the action of man.

In Tasmania, however, lived longer (from this comes the name Tasmanian Tiger or Tasmanian Wolf) and the last copy of this region in the wild was killed in 1930. In addition, it is worth mentioning the last Thylacine lived in captivity (pictured above) died in 1936.

In the Decade of the 1960s, it was believed that they could still exist some small populations of Thylacines, so the final extinction declaration did not arrive until 1980. However, today there have been occasional reports of sightings in Tasmania and New Guinea.


There is a single photograph of a Quagga, of the female which can be seen here above, taken in London Zoo. The Quagga was a subspecies of the Zebra of the plain, which lived in large groups in South Africa. However, this animal hunted to extinction to take advantage of their meat and skin, as well as to feed other pets.

The last wild Quagga was killed in the Decade of the 1970s and the last specimen in captivity died in August 1883. It is interesting to mention that the DNA of the Quagga was the first of an animal extinct to be examined. Before carrying out this study, it was believed that it was a totally different from the Zebra, not a subspecies species.


The tarpan or Eurasian wild horse lived until sometime between 1875 y1890. The last exemplary savage was killed during an attempt to capture and the last animal in captivity died in 1918.

The tarpanes were something less than a meter and a half tall and had a thick coat gray in color, with darker legs and rays in the dorsal area. There are discussions about if this photograph is a true tarpan or not, but still arguing that this image is the only one that exists of a live tarpan.

The Seychelles giant tortoise

There are some discrepancies about if the Seychelles giant tortoises are extinct completely or only in the wild. In the 19th century turtle giant Seychelles, very similar to other species of turtles from other islands of the Indian Ocean, was indiscriminately hunted to extinction. But before being eradicated from the wildlife, specifically around 1840, he lived only on the shores of swamps and streams, feeding on vegetation.

On the island of La Digue, however, exist in captivity over a dozen giant tortoises that might actually be the Seychelles giant tortoises. In addition, on an island in the South Atlantic called St. Helena, lives another turtle from around 180 years which could also belong to this species.

Berberia Leon

Famous from Morocco up to Egypt, the Barbary lion (also known as the Atlas Lion) was the largest Lion subspecies and heavier that existed. Unlike other lions and mainly due to the scarcity of food in their own habitat, this cat did not live in herds.

The last wild Barbary lion was killed in the Morocco Atlas mountains in 1922. However, today still raises doubts about whether some of the lions that live in captivity in certain zoos and circuses in the world could be direct descendants of this animal. A historical note: the Lions who engage in gladiatorial combat from the time of the Romans probably were Barbary Lions. This photo taken in Algeria dates from 1893.

Bali Tiger

Without a doubt, this image taken in 1913 is not very clear. Even so, documents the existence of one of the three subspecies of Tigers of Indonesia, the smallest subspecies that ever existed of this animal: the Bali Tiger. The last Tiger of Bali which has record was murdered in September 1937, although it is suspected that some specimens of this species continued to live until 1940 or 1950.

The loss of habitat and indiscriminate hunting (mostly carried out by European, Balinese do not) led him to the point of extinction. Bali Tigers had a coat shorter and darker than the rest of the Tigers and similar in size to the leopards, and mountain lions.

The Caspian Tiger

At the opposite end of the scale of the Bali Tiger is the Tiger of the Caspian, one of the larger cats that has never existed. It was a little smaller than the Giant Tiger of Siberia and lived on the shores of the Black Sea, along the Caspian Sea in what is currently known as Iran of the North, Afghanistan, the former Soviet Republic in Central Asia and Western China.

The Caspian tiger was systematically pursued until their extinction at the end of the 19th century with the Russian colonization of the Turquestn. Regionally began its journey toward extinction in 1887 in Iraq, and the last confirmed sightings occurred in the Decade of the 1970s at the borders of Turkmenistan, Uzbekistan and Afghanistan. Anyway, were reported sightings not confirmed until the beginning of the 1990s.

Western black rhinoceros

The plight of the Rhino due to illegal hunting has been very well documented on TreeHugger; and the Western black rhinoceros is a graphic example of this situation. This species that abounded in central Africa was declared extinct in 2011.

While conservation efforts initiated in the Decade of the 1930s contributed to the recovery of the species, in the Decade of the eighties protection decreased, resulting in the revival of poaching. At the beginning of the 21st century there were only ten copies and all of them had been killed by the year 2006.

Golden Toad

The golden toad is an iconic species in what refers to the extinction. Only described in science in 1966 and prolific sometime in an area of eighty square kilometers of the cloudy forest of Monteverde, in Costa Rica, it has not been to any of these toads to five centimeters long from May 15, 1989.

The reason for this sudden disappearance is not known with accuracy, although habitat loss and citridos fungi are the possible culprits. Also considers that regional climate changes caused by the current of the child could have played a very important role in the extinction of the last Golden toads.

Pinta giant tortoise

The giant tortoise from Pinta, a subspecies of Galápagos tortoise, could be one of the last giant animals declared extinct. The last issue of its kind, a more than 100 years old male nicknamed "el Solitario George" (pictured above) died on June 24, 2012 for heart failure.

It was assumed that this species had become extinct in the mid-20th century (the vast majority of these turtles were killed at the end of the 19th century), but George was discovered in 1971. In addition to the hunting of man, the introduction of non-native species such as goats, contributed to the habitat loss that caused the extinction of these turtles.
