Extinct Animals

The Thylacine (Thylacinus cynocephalus, also known as the Tasmanian Tiger and sometimes the Tasmanian Wolf), became extinct during the 20th century. The last known specimen died in the Hobart Zoo on the 7th of September, 1936.

It was hunted to extinction after a bounty was placed on it as a livestock killer. The government paid one pound for every dead adult thylacine head, and ten shillings for every dead thylacine pup head. Also, wild dogs that settlers brought in competed with the thylacines, reducing the prey of the thylacine.

The thylacine and Tasmanian devil both became extinct in mainland Australia hundreds of years earlier, probably because they were in competition with dingoes once the Aborigines came.

There is disputed evidence that a very small number may yet still exist in the Tasmanian wilderness, but nobody has seen, photographed or trapped one.

A recent attempt was made to clone one, but failed due to the DNA being of insufficient quality.

Further, it has been suggested that, in the early part of the Twentieth Century an extremely virulent disease began to spread first through the wild then captive populations. Exactly what this disease was remains unknown but it was described as being similar to but distinct from canine distemper. Another theory points to the fact that, by the time the Thylacine was confined to the island of Tasmania, the remaining specimens did not have sufficient genetic diversity to sustain the population. A similar problem is currently affecting the Tasmanian devil, resulting in the spread of the fatal DFTD, or Devil Facial Tumour Disease.

because back in the 1800's there was this huge asteroid that hit the earth. since it was so big all the dinosaurs in the world all died and now u can find dinosaur tracks on the ocean floor, rivers, lakes, and other bodies of water.so they died and became extinct because of the asteroid. that's how it happened

Pterosaurs were a very diverse animal order comprised of numerous species which occupied many ecological niches, therefore the diets of different pterosaur species were likely as diverse (or almost as diverse) as, say, the various diets of modern birds. Some pterosaurs were piscivorous (fish eaters), whether skimming the surface as modern seabirds do, or waiting on the banks of lakes and other bodies of water for fish to approach. Many hunted insects (especially the case with smaller, earlier pterosaurs) and other invertebrates, or small vertebrates such as lizards and other reptiles, or even the mammals that were around during the Mesozoic. The larger ones (such as the enormous Azhdarchids) could probably devour small or juvenile dinosaurs whole, and might also have been efficient scavengers like modern vultures. At least some Ctenochasmatid pterosaurs were filter feeders analogous to modern flamingos (Pterodaustro had over 500 thin, closely spaced teeth which it used to very efficiently filter food from the water), there are even some extremely speculative and probably fictitious ideas that some pterosaurs were haematophagous, i.e. blood drinkers like modern vampire bats. All in all, the pterosaurs as a group consumed a wide range of available foods, although one could make a reasonable assumption that since all known pterosaurs were flying animals, and considering that flight is a very energy-intensive activity (and that it puts an upper weight limit on the animal), the pterosaurs would have been biased towards high-energy food sources that are fairly simple to digest such as meat.

I am no expert on the subject, but it seems that someone should start this entry. Some primary reasons that animals become extinct include loss of habitat, changing climatic conditions, introduction of non-native species or predators into their habitat, pollutants, and predation by humans.

The reason for its disappearance was probably habitat destruction. It is not known why it was always considered rare, but the rarity is believed to be genuine (and not an artifact of insufficient fieldwork) as its erstwhile habitat was frequently scoured by hunters in Colonial times.

by not polluting the air, recycle,stop wasting trees to make too many paper which destroying the habitat for animals

go to people and say STOP if they don't listen complain to the President

Awake magazine article - 11/22/01 pg 3 had this to say: "Today it is humans who should accept responsibility for the increasing rates of species extinction." JANE GOODALL., CONSERVATIONIST.

Some scientist claim that 50 percent of all plant and animal species could vanish from the earth in 75 years. Scientists believe that in the distant past, species extinction was mostly triggered by natural causes. But the principal cause of the present crisis is different, they say. Evidently today's extinctions are caused by human activity. One scientist referred to humans as the "exterminator species."

human activity such as littering can affect the extinction of plants and animals in many ways. the plants can take in the harmful chemicals from products left around that were absorbed in the soil and could poison them. This would cause them to die. Animals could eat the stuff lieing around and could cholk and die. I dont really now this 100% but i know it can happen.

well there are many ways they have had gotten extinct some say it was a change in climate ( ice age) or it could have been a meteor scientist are still arguing to answer this question ( i personaly think that it was a change in climate because it explains all those furry critters like the mamonth plus if a metor hit it would maybe cause the earth's orbit to change a little yes i know i smart smart ) :) :)

I dont believe either of those, but, maybe they just died? o.O

The international groups and nations that publish lists of plants and animals in peril and who monitor and track the numbers of animals in a species for species protection, each have their own criteria for listing each species and define the statuses under which they are listed. Their criteria and definition varies between the different lists and statuses. More information is available on the methodology of listing endangered species at the sites linked below in the related links section.

Although there were sharks in the Mesozoic Era, Carcharodon megalodon was not one of them. C. megalodon lived during the Neogene Period, 40 million years after the dinosaurs went extinct.

One example of a dinosaur with 12 letters in its name is "Stegosaurus." Stegosaurus is a herbivorous dinosaur known for its distinctive plates along its back and spikes on its tail. This dinosaur lived during the Late Jurassic period, around 155 to 150 million years ago.

Iguanodon lived in Europe between 126 and 125 million years ago. At this time, Europe was tropical to subtropical and much of it was covered by shallow seas. The islands that were not flooded were relatively dry and covered in forests of conifers, cycads, ferns, horsetails, and ginkgos.

The animal doesn't necessarily have to be "missing" however the numbers will be scarce and its habitat affected by either natural or human activity for the species to be considered endangered. For the species to be considered extinct, there would have to be no more evidence to prove the animal's existance.

A baby alligator is called a hatch-ling. This is a common name used among most reptiles that give birth by laying eggs. There is no specific name for the baby of an alligator.

A group of young alligators is called a pod.

To bite into prey or bite leaves, dinosaurs needed teeth. The T. Rex had the biggest teeth of all dinosaurs to deliver a killing bite to its prey. The sauropods had front teeth but no back teeth. The spinosaur adapted to eating fish and so had a mouth like crocodiles.

the were hunted and killed for meat and sport until they were gone

Well, to start, we can buy cans with the label "dolphin safe" on the side, and you can cut up can loops so the dolphins don't get there heads caught in it.

or/and we can recycle reuse and join save the dolphins, beside that you can go on a site called savethedolphins.org and sign their petition to help save the dolphins from being slaughtered.

You have to seek out a organization near you that looks after dolphins and donate large sums of money to them. It will mean you wont have a big bank account but you will feel happy and contened! So go out save the dolphins and go help the world!

It lived from 370,000 to 10,000 years ago but there are some signs of cave lions living around 1200 A.D.

Since Dino's have been extinct fOr over 1 million years, scientists have almost proved dinosaurs will not ever come back since they have left no DNA

You have to wait 6 days until it hatches, once it hatches you can walk it. After 20 days it will be able to dance, day 30 it can fly, on day 50, your pet dragon will be able to breathe fire.

It would throw it out of balance

It does not respond to changes,does not need air,food and water.It does not die

Basically almost all African Savanna animals are endangered. Especially elephants and rhinos because of their ivory( a.k.a white gold) but others are endangered due to people settling on their home. Lions are threatened because of fear of attack.
