Extincted Animals
There is a very huge diversity of organisms in this world.they shape a beautiful diversity on this earth.But now most of the organisms facing greatest threat of extinction from humans and other sources..
In this article i introduce some varieties of animals that survived strongly on past and disappear from world due to some unknown problems..
DINOSAURS
It isn't hard to imagine the world full of dinosaurs,..Eeven though these extinct animals haven't walked the earth for millions of years. Learn all about dinosaurs, including early dinosaur discoveries, dinosaur fossils, and dinosaur extinction.
Most people think of dinosaurs as big, ferocious and extinct reptiles.
That's largely true, but there are some misconceptions.
Dinosaurs came in all shapes and sizes. Dinosaurs were the largest land animals of all time,
but a great number of dinosaurs were smaller than a turkey.!!!
Dinosaurs appear first about 250 million years ago.
They ruled the Earth for about 135 million years until an extinction event 65 million years ago wiped out all but bird-like dinosaurs. Scientists don't agree entirely on what happened, but the extinction likely was a double or triple whammy involving an asteroid impact, choking chemicals from erupting volcanoes, climate change and possibly other factors..
Everyone imagine that they are very gigantic animals..
no one knows the real facts about these huge animals,Dinosaurs..
Mammoth, an extinct animal related to and resembling the elephant. Mammoths were abundant during the Ice Age.
They are very gigantic animals lived in prehistoric era..
They highly resembles Elephant.
Mammoths had long curved tusks, shaggy dark hair, and humped backs.Thousands of mammoths have been found frozen in the soil of Siberia and Alaska. Many are perfectly preserved, even to the stomach contents mostly grass and leaves. Remains of dwarf mammoths, which were about six feet (1.8 m) high at the shoulder, have been found on islands off the coasts of California and Siberia.
Stone Age people hunted mammoths and drew pictures of them on the walls of caves. Most mammoths became extinct about 10,000 years ago; some dwarf mammoths lived as recently as 4,000 years ago. Over-hunting by humans and a warming of the climate may have together caused the extinction of mammoths.
Extincted Birds
DODO
Dodos were flightless birds the size of large turkeys.
Dodo, a large flightless bird that once lived on the island of Mauritius in the Indian Ocean but is now extinct. The dodo was related to the pigeon, but was the size of a large turkey. Its body feathers were gray; breast and tail feathers were white. A bulbous hooked beak, short, stubby legs, and curly tail feathers gave the dodo a comical appearance. The dodo was a clumsy, slow-moving bird but it flourished on Mauritius because it had no natural enemies.
Solitaires, birds related to the dodo, lived on the nearby islands of Runion and Rodriguez. By 1800 they, too, had become extinct.
The dodo and the solitaires belonged to the family Raphidae. The dodo was Raphus cucullatus; the Runion Island solitaire, R. solitarius; the Rodriguez Island solitaire, Pezophaps solitaria.
Stellers Sea Cow
The Stellers sea cow was a large marine mammal that was found in abundance in the North Pacific. These enormous animals were closely related to the dugong and the manatee still found grazing in the oceans today, but were of considerable size at between eight and nine meters in length.
The Stellers sea cow was first discovered in 1741 by explorers that ventured into parts of the Arctic Circle. When they were first recorded, the Steller's sea cow was said to be living in abundance in the North Pacific, however in less than 20 years of human contact, the Stellers sea cow had disappeared from the ocean completely.
The sabre-toothed tiger is one of the most well-known prehistoric animals along with giants such as the woolly mammoth. Sabre-toothedtigers roamed the mid-western US and parts of both North and South America and were named for the enormous canines which skeletons show, protruded quite far out of their mouths.
Despite it's name, the sabre-toothed tiger was not actually related to the modern tigers that are found throughout the jungles of Asia. It is thought that the sabre-toothed tiger would have roamed across the grassland plains and open woodlands throughout both North and South America where individuals would of varied slightly depending on the area which they inhabited.
The sabre-toothed tiger is one of the best known ice-ageanimals but little is really known about them as they are thought to have become extinct around 10,000BC which is a long time ago. The sabre-toothed tiger was named for the canines that could grow to more than 7 inches in length and were capable of fatally wounding their prey with one bite.

Passenger Pigeon
The earliest settlers in the New World were amazed by the passenger pigeon, a bird with flocks so huge that it would take days for them to travel overhead, blackening the sky as they passed.
Any farmer who had the misfortune of hosting passenger pigeons for a meal would quickly find his entire crop decimated within the blink of an eye. Then, virtually overnight, the most abundant bird in North America suddenly disappeared from the planet.
The extinction of the passenger pigeon is an example of nature coming into direct conflict with man. Its population numbered an astounding 3 to 5 billion when the first Europeans arrived in America. However, there was not room enough in the New World for both species.
Passenger pigeons were soon wiped out due to merciless hunting, deforestation and other factors related to humankind's ever-expanding range. The extinction was only becoming apparent at the start of the 20th century; by 1914, the last known bird was dead.
Quagga
The Quagga is a mammal closely related to modern horses and zebras. In fact, it looks like a cross between a horse and a zebra, with stripes only on its head and neck that disappear as they approach the brownish hindquarters of the animal. The quagga was native to desert areas of South Africa until it was hunted to extinction in the 1870s. The last captive animals died in Europe in the 1880s.
As an extinct species, the quagga has a couple claims to fame. For starters, it was the first animal to have its DNA analyzed, which led to the discovery that the quagga was not a distinct species but a subspecies of the plains zebra. Also, the quagga is the subject of an ambitious breeding effort by the aptly named Quagga Project, the result of which was a foal born in 2005. Based on appearances, the "re-created" quagga closely resembles the ancient quagga, but DNA evidence has yet to determine whether this animal is authentic.
Vancouver Island Marmot
The rodent is one of the most endangered mammals in North America, with less than 40 individuals found in an area less than 10 sq. km. Logging is most likely the cause of its diminishing numbers.
Black Rhino
The population of the black rhino declined by 90% over the last six decades, thanks chiefly to poaching. But since the mid 1990's — when fewer than 3,000 of the African rhino existed — the population has increased steadily, and now there are over 4,000.
Iberian Lynx
Believed to be the most endangered mammal in Europe, the Iberian lynx, found mostly in Spain, has fewer than 150 individuals in the wild. It's dying out because its main source of food — a rabbit — is also declining rapidly.
