Extinct Animals

The Loch Ness Monster, AKA. "Nessie", is a fictional creature. There is no proof that she does exist although there have been many hoaxes. These hoaxes range from plastic swans and fake radar images. There are reports of sonar images having picked up on a large shape ("Nessie") followed closely by a much smaller shape (possibly a baby "Nessie").

Unfortunately, "Nessie" is a mythical type of animal. In other words, she does not exist.

Just because something is mythical does not mean it does not exist.

Animal extinction is a bad thing because each animal has a function in an ecosystem. Ecosystems are delicate and removing a piece of them, no matter how small, can have dramatic consequences for the entire ecosystem. For example, if all the fish died a river, the animals that eat them would starve and eventually leave or die off. In addition, everything that the fish ate would be left without a predator and overrun the ecosystem, possibly forcing out other species and depleting a resource.

bears died out in England around 700-800AD

I don't think this is true as in the Domesday book the men of Norwich were required to provide one bear, and 6 dogs to bait it, to the King each year. So bears were still around until at least the 11th century.

conserve them in zoos,whilst doing this breed them and then set 1 in 3 back into the wild.

There is at least one instance were you can directly account for many extinction by one cause, MAN. As a species we are very adapt at killing everything that we do not value or care enough about. We kill many species a year and also have driven many more to the brink of extinction. Some of which are beyond saving, they are dead animals walking as it were.

There is possibly another example where 1 event possibly lead to a chain reaction which cause the worst extinction event in Earths history, the Permian-Triassic extinction or "The Great Dying".

The theory although controversial explains exactly all the evidence we can see today.

About 251 million years ago it is believed an asteroid about the same size of the Chicxulub Asteroid struck earth just of the coast of Australia. It has been suggested that the shock waves from this asteroid concentrated on the opposite side of the planet at the antipodal point causing a huge volcanic eruption in Siberia, the so called Siberian Traps. Gases from this volcanic eruption caused a large greenhouse effect and warmed the planet.

This increase in temperature in turn stopped the ocean conveyor (a set of currents that circumnavigate the oceans spreading warmth from the equator to the poles and also bringing oxygen to the deep ocean). Once the ocean conveyor had stopped the deep oceans suffered anoxia. This allowed anaerobic bacteria to flourish. One by product of these bacteria is an extremely poisonous gas called Hydrogen Sulphide. This gas was formed in such quantities that it bubbled out of the ocean and killed anything it came in contact with. An example of this anoxic state and hydrogen sulphide making bacteria can be found in Green Lake in New York State.

that would be either a hypothesis or theory

Any of the African preditors would have eaten these animals including lions, hyena, leopards, wild dogs, and cheetah. The quagga was also hunted for meat and hides and to eliminate their competition for grazing land of livestock. The last wild quagga died in a zoo in Amsterdam in the late 1870s.

they never did die out, but they evolved into a more clever species with larger brain spans and carried on evolving into us (homo-sapiens)

there were several groups of creatures on Pangaea. but for going the insects there where 4 major groups amphibians, anapsids diapsids and therapsids. the amphibians where remnants from the coniforus still large but not dominante on land anymore. anapsids accounted for a good chunk of life on land at this time. therapsids or so called mamal like reptials (eventualy evolved into mamals) where very common but the ones you know about are the diapsids. thees included crocidiles lizards and dinosaurs.

Pterosaurs died out 65.5 million years ago during the K-T Extinction Event. The K-T Extinction Event not only wiped out the pterosaurs, but all non-avian dinosaurs, the plesiosaurs and mosasaurs, and many types of plants and animals that are not as well known today. In fact, it is believed that 75% of species went extinct.

Megalodon did exist. Their teeth were commonly found fossils for hundreds of years before it was discovered that they were actually the teeth of a giant shark. Before that, they thought that the teeth were the petrified tongues of dragons! Megalodon were sharks, that may have been up to 50 feet long, and who commonly hunted whales. They existed between 25 and 1.5 million years ago.

No extinction is as well documented as that of the New Zealand Moa (pronounced mo-ah).

It was a large flightless bird of the order Dinornithiformes. Weighing up to 250Kg and 2.5 metres high, it was hunted to extinction by the Maoris by about 400 years ago.

The Moa occupied the ecological niche in New Zealand of the antelope, rhinoceros and kangaroo and lived in habitats from forest to alpine tundra.

They were abundant when the Maoris arrived in New Zealand about 1,000 years ago. However there is no real evidence to show that the Maori people were solely responsible for their extinction. It was thought that Moa were easy to catch due to a lack of natural predators although the Harpogonis Eagle was thought to be the main natural predator.

Dr Tim Flannery's book, "The Future Eaters" gives a good account of the extinction of the Moa and he quotes "Prodigious Birds" by Atholl Anderson as a "splendid work on the Moa". Atholl Anderson was also famous for proclaiming that polynesians somehow accidently discovered polynesian islands through his drift theory. This has been disparoved over a decade ago.

Tasmanian tigers, more properly known as Thylacines, were warm-blooded, like all mammals.

yeah .

Yes. They're known as TRACE FOSSILS, as opposed to the BODY FOSSILS that are the preserved bones of ancient organisms. Trace fossils should not be dismissed as immaterial or relatively useless. A tremendous amount of information can be gleaned them

The elephant birds and dodo birds both lived in the tropics, not anywhere near the North Pole. Elephant birds were native to the African island of Madagascar. Dodo birds lived on the Muaritius Islands, also off the coast of southern Africa.

A quagga is an extinct subspecies of zebra. They were believed to be about 8 foot 5 inches long and about 4 foot high at the shoulder.

Yes. There have been several episodes of mass extinction. The worst was at the end of the Paleozoic era. The most famous came at the end of the Mesozoic, when the dinosaurs disappeared. Nature is cruel.

Of course, some people say that species have not really become extinct, but merely evolved into different forms.

lots of wild non home livings ones so DON'T POLLUTE

Living things have the following things in common that non-living things do not have:

1.Reproduce

2.Give off waste

3.Use Energy

4.Have cells

5.Have DNA

6.Grow and develop

7.Need Water

bout 2,5603 animals this year mostly bacteria and viruses but also several insects and mammals ,because of pollution ,because of over hunting ,because of alcohol and chloride and antibiotics,by electrical arrangements ,in short all because of history ,technology, and nuclear reactors

A Quagga only has stripes on its front half; a Zebra over its entire body.

No, a Mastodon is an extinct species of ancient elephant. Mastodon lived in the Cenozoic Era, not the Mesozoic Era.
