1 LIST OF EXTINCT SPECIES CLASS - 4KV SALUAK.Singh
2 Extinct AnimalsExtinct animals means those animals are coming to an end or dying out.
3 Species go away forever for a lot of different reasons: ice ages, catastrophic meteor collisions ... and, of course, there's the persistent threat of one particular predatory, parasitic, highly adaptable species: Homo sapiens (that would be you and me).We didn't do all these species in, but we've certainly had a hand in some of their demises.
5 1: The Dodo (Raphus cucullatus) The flightless bird, native to the island of Mauritius, in the Indian Ocean, was known to mankind for less than 100 years ... but that's all it took for us to eradicate the species.It wasn't so much that humans killed the stubby, rotund birds directly.The last dodo died sometime in the late 17th century. Since then, the bird (a relative of pigeons and doves) has become a poster child for extinction and a reminder of the havoc we can wreak as human beings.
7 2: The Dinosaurs, all of them They were gone long before the first human graced the planet, yet they've still managed to capture the hearts of school kids across the globe, thanks to the toys, cartoons and museums full of skeletons extolling their prior existence.And wouldn't it be nice if the dinosaurs all lived together like they do in the movies, playing, fighting and hunting? Think more The Land Before Time and less Jurassic Park, more plant-eaters and fewer Velociraptors. The reality is that many of the more famous dinosaur species never even crossed paths.They've captured our hearts in a way that no other extinct animals have ... and when it comes down to it, we should probably just be thankful that we never knew those Velociraptors, right?
9 3.Tyrannosaurus Rex (extinct 65 million years ago) Tyrannosaurus rex was one of the largest land carnivores of all time.It measured up to 43.3 feet long, and 16.6 ft tall, with an estimated mass that goes up to 7 tons. Fossils of T. rex have been found in North American rock.
12 4. Great Auk (Pinguinus impennis) At nearly 3 feet tall, the great auk was a large bird.The last known auk in Scotland was executed in 1840.The last flightless bird in the Northern Hemisphere and once inhabited islands off the coast of northern Europe and northeastern North America.
15 5. 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
