Extinct animals are those species that are no longer living in this world. Over the years, many animals have gone extinct and there are many all over the world facing this danger including mammals, birds, reptiles, amphibians, fish and invertebrates. A species is declared extinct after many years of not being spotted. Chances are there that many species are already gone that we are unaware of since it takes so long to define an entire species as extinct.

The five reasons for extinction are the destruction of its habitat, overuse of the species for multiple purposes, disease or predation of the species, lack of protection or natural or man-made hazards to the species. We are presently losing dozens of species every day, according to the Center for Biological Diversity. Below we have mentioned a few of these extinct animals over the years.
Tyrannosaurus Rex – Dinosaur
Tyrannosaurus Rex was, as many people would know it, one of the largest carnivores of all times. It was as long as 43.3 feet, and 16.6 feet in height tall, with an estimated weight of as high as 7 tons. Tyrannosaurus was a bipedal animal having a massive skull that was balanced by a long and heavy tail. The hind limbs were large and powerful, while the forelimbs were quite small. This species was one of the most dangerous animals since the beginning of dawn.
Quagga: Half Zebra Half Horse
Quagga makes up for one of the most famous extinct animals in the wildlife of Africa. It was actually a subspecies of zebra, although it differed from it due to the presence of marks on the front body only.
Thylacine: The Tasmanian Tiger
Thylacine was recently made extinct due to excessive hunting and was found in small numbers in Australia and New Guinea. It was commonly referred to as the Tasmanian Tiger and also the Tasmanian Wolf.
Steller’s Sea Cow: The Defenseless Beast
The animal resembled a large seal; however, had two forelimbs and a tail like a whale. The animal always lived in the water and had black and thick skin. The main cause for the extinction of these species was the arrival of humans in this area.
Irish Deer / Elk: The Largest Deer That Ever Lived
Irish Deer or Elk was also known as the Giant Deer, due to the fact that it was the largest deer that has ever set foot on this planet. It also became extinct a long time ago about 5000 years ago.
