>~Tyrannosaurus Rex(extinct 65 million years ago) Tyrannosaurus rex was one of the largest land carnivores of all time, measuring up to 43.3 feet long, and 16.6 ft tall, with an estimated mass that goes up to 7 tons.[img=http://www.oddee.com/_media/imgs/articles/a98_Rex.jpg] Fossils of T. rex have been found in North American rock formations dating to the last three million years of the Cretaceous Period at the end of the Maastrichtian stage, approximately 68.5 to 65.5 million years ago; it was among the last dinosaurs to exist prior to the Cretaceous-Tertiary extinction event. >Quagga half zebra, half horse (extinct since 1883) One of Africa's most famous extinct animals, the quagga was a subspecies of the plains zebra, which was once found in great numbers in South Africa's Cape Province and the southern part of the Orange Free State. It was distinguished from other zebras by having the usual vivid marks on the front part of the body only.The quagga was originally classified as an individual species, Equus quagga, in 1788. [img=http://www.oddee.com/_media/imgs/articles/a98_Quagga.jpg]The last wild quagga was probably shot in the late 1870s, and the last specimen in captivity died on August 12, 1883 at the Artis Magistra zoo in Amsterdam. >Thylacine the Tasmanian Tiger (extinct since 1936) [img=http://www.oddee.com/_media/imgs/articles/a98_Thylacine.jpg] The Thylacine was the largest known carnivorous marsupial of modern times. Native to Australia and New Guinea, it is thought to have become extinct in the 20th century. It is commonly known as the Tasmanian Tiger (due to its striped back), and also known as the Tasmanian Wolf, and colloquially the Tassie (or Tazzy) Tiger or simply the Tiger. The Thylacine became extinct on the Australian mainland thousands of years before European settlement of the continent, but survived on the island of Tasmania along with a number of other endemic species such as the Tasmanian Devil. >Steller's Sea Cow: the defenseless beast (extinct since 1768) Formerly found near the Asiatic coast of the Bering Sea, it was discovered in in 1741 by the naturalist Georg Steller, who was traveling with the explorer Vitus Bering. The sea cow grew up to 7.9 meters (25.9 ft) long and weighed up to three tons. >Irish Deer : the largest deer that ever lived (extinct about 7,700 years ago) The Irish Elk or Giant Deer, was the largest deer that ever lived. [img=http://www.oddee.com/_media/imgs/articles/a98_Irish.jpg]. It lived in Eurasia, from Ireland to east of Lake Baikal, during the Late Pleistocene and early Holocene. The latest known remains of the species have been carbon dated to about 5,700 BC,or about 7,700 years ago. The Giant Deer is famous for its formidable size (about 2.1 meters or 7 feet tall at the shoulders), and in particular for having the largest antlers of any known cervid (a maximum of 3.65 meters/12 feet from tip to tip and weighing up to 90 pounds).
