Extinct Animals

Extinct animals are species that have been completely killed off and are missed by humans years after extinction. Dramatic environmental changes, humans over hunting, poaching and more have caused many animals to become extinct. From the Irish Dear to the Dodo, there are countless animals that will never be seen again.  

  1. Tyrannosaurus Rex. The largest carnivore species of all time was Tyrannosaurus Rex; weighing approximately seven tons, 43.3 feet long and 16.6 feet tall. Fossils of Tyrannosaurus Rex were found in North America, and were estimated to be from the last three million years of the Cretaceous Period. Tyrannosaurus Rex have been extinct for more than 65 million years, but they will be remembered forever for their massive size, large skulls and small forelimbs with two digits.  Some of the top funny animal videos and movies involve the Tyrannosaurus Rex, such as Toy Story.

  2. Stellar's Sea Cow. George Stellar discovered Stellar's Sea Cow along the Asiatic coast of the Bering Sea in 1741. Stellar's Sea Cow resembled manatees and whales; they had short forelimbs, tails similar to whales, black skin and body shapes similar to manatees. They were defenseless, large beasts. This species grew up to 30 feet long and weighed about eight to ten tons. Shortly after they were discovered, they became extinct in 1768 due to sailors, seal hunters and fur traders.

  3. Irish Deer. This species of deer was gigantic, standing at seven feet tall at the shoulders. The Irish dear was the largest deer that ever lived, and it unfortunately became extinct approximately 7,700 years ago. It lived in the areas of Eurasia, Ireland and Lake Baikal. The most amazing thing about the Irish Deer was the twelve feet span and 90 pound weight of their antlers.

  4. Caspian Tiger. If someone saw a Caspian Tiger, they would marvel at its large claws, wide paws, massive legs and resemblance to the Bengal Tiger. Caspian Tigers were the third largest species of tigers, and they lived throughout the lands of Iran, Iraq, Afghanistan, Turkey, Mongolia, Kazakhstan, Caucasus, Tajikistan, Turkmenistan and Uzbekistan. Males weighed from 371 to 528 pounds, and females weighed 187 to 297 pounds. They became extinct in 1970 directly due to poaching and deforestation.

  5. Dodo. These birds are some of the most well known extinct animals, because their extinction proved that humans can have a large impact on animals. Flightless, three feet tall and a berry eater, the Dodo birds did harm to no one. Dodo birds were related to penguins, built small nests on the ground, lived on the island Mauritius and were flightless. They became extinct during the 17th century.
