What year did the toxodon become extinct?
Like many ice age species, it became extinct at the end of the Pleistocene Epoch 16,500 years ago.
Your question does not really make sence - so I'll assume you mean
"How does a swan fly?"
And the answer is - by pushing their wings up and down. In other words - flapping them.
What was the fourth major extinction event?
During the 4th Extinction, or Triassic-Jurassic extinction, 90% of all species died within just 10,000 years. The 4th Extinction was thought by many scientists to have been caused by massive volcanic activity or asteroid impacts resulting in severe climate change.
When did the Tyrannosaurus Rex became extinct?
Fossisl specimens date from about 126 million years ago, plus or minus a couple of million years. Unless and until a more recent fossil is found of Utahraptor, this should be considered the extinction limit.
How many teeth does megalodon?
Most sharks have about 3-5 rows of teeth at any time. The front set does most of the work. The first two rows are used for obtaining prey, the other rows rotate into place as they are needed. As teeth are lost, broken, or worn down, they are replaced by new teeth. Megalodon may have had hundreds of teeth at one time.
When did predator X go extinct?
nowadays many animals are became extinct because there is a change in environment so a lot of them facing crises as water sources dry up specially in Africa and water and food shortage in addition habitat loss due to forest devastating moreover poaching and pollution how menace the earth
Aurochs were found in North America and Europe; the last one dying out in Poland in the year 1627.
What caused the megalodon shark to become extinct?
Yes. Scientists believe that they died out approximately 1.5 million years ago. See the related link for a picture.
*That is the popular thinking, but there is evidence to the contrary. As well, the ceolecanth was believed to have been extinct for millions of years. Until people began catching them. There is no way to prove beyond a shadow of a doubt that they truly are extinct.*
What is the number one cause of current animal extinctions?
If you were asking for main reason for mass extinctions in general, I would say that it is abrupt climate changes.
However the K-T mass extinction was a consequence of a major comet/asteroid impact, and perhaps the Ordovician-Silurian mass extinction (the second largest mass extinction after the Permian extinction, the «Great Dying») could have been caused by a Gamma-ray burst from a supernova (or hypernova) explosion thousands of light-years distant, or could have been the outcome of the most severe glaciation of the Phanerozoic eon.
The most severe of all mass extinctions was the above mentioned Permian mass extinction, and the reasons for such a catastrophic event are not yet fully understood.
But you asked which is the main reason for the CURRENT extinctions. Indeed the scientific community believe that we are now watching a new MASS EXTINCTION, not just the extinction of a limited number of species.
I am sorry to say that I, personally, believe the reason is human beings.
And I know well this is currently a matter of debate and vigorous scientific and political dispute, due to the monstrous profits of polluter industry, along with the big bank's investments and the high finance lobbies supporting these industries.
Did woolly mammoths travel alone?
Like elephants today, the Woolly Mammoth were social animals, and the females lived in related groups or herds.
Until the male mammoth reached the age of three to four years of age, he also lived with this group of closely related females. At that age, he started exploring his world and left the group behind. For two to three years after he left the female herd, he may have lived with a nomadic band of other male like age mammoths. This was called a bachelor herd.
Males were not usually related to each other in the bachelor herd, and came and went as they chose. As the males reached the age of 20, they no longer associated with herds of either sex unless it was time to breed.
What is factors may have caused the extinction of woolly mammoth?
As the world got warmer the woolly mammoth habitat decreased their source of food and as the human population grew the more hunters their was around to hunt the mammoths so that could drove the last of the mammoths to extinction
How big were the saber tigers teeth?
Sabre-Toothed Tiger teeth were approximately 17 cm (7 inches) long. Their teeth did NOT continue to grow through their life.
The 2 types of tiger had the following sized teeth: Genus Homotherium-4 Inches Genus Smilodon-7 inches
"Smilodon" had ENORMOUS teeth! -I've seen them (the top two being the longest) as long as eight inches! The La Brea tar pits near Los Angeles, California has produced the largest collection in North America.
What features do mastodons have that were unique to its survival?
Woolly mammoths had far too many adaptations to list them all. Here are a few of the adaptations that they had:
1. Like modern elephants, they had a long trunk for grasping food.
2. Their large size would have made them difficult to hunt, even for a skilled predator.
3. Woolly mammoths had a thick layer of fur, as well as a thick layer of fat, to keep them warm in the cold tundra climate.
4. The fact that they had small ears minimized heat loss.
How big was the short face bear?
The biggest short faced bears were Agriotherium Africanum at 650 kg, Arctodus Simus at 700 - 800 kg( large males could weigh a tonne) and Arctotherium angustidens at 1000 kg, eventhough large males could get to 1500 kg.
Why did giant koalas become extinct?
Koalas as a species are a long way from extinction. There are however regional areas of Australia where traditional populations of these animals are under threat due to the usual man made problems of urban development, deforestation etc. Despite all this, the koala is holding its own and has many areas of protected habitats to live in. On an island off the southern coast for instance, there are literally too many koalas for the food sources to keep up and the solution for this still hasn't been worked out. One drastic idea put forward is to destroy a certain number of koalas so that equilibrium can be established.
Koalas are protected and have been protected for a long time. They are not found in all areas of Australia. They are being pushed out of their natural habitat by urban growth. Koalas are also dying from a disease called Chlamydia, infecting the eyes and causing blindness, and compromising the koala's fertility.
The conservation status of koalas varies from region to region in Australia, but they are by no means becoming extinct. For example, due to farming and land clearing, native koalas were eradicated from Western Australia and South Australia in the last century, but moves have been made to reestablish new colonies in both states. Currently, koalas are thriving on Kangaroo Island in SA, and in other isolated colonies throughout SA's southeast.
Koalas are still listed as "common" in most parts of Queensland, but in the southeast region of Queensland, their status has been changed to "vulnerable". The NSW Government listed the koala as "rare and vulnerable" in 1992, and following protective measures, this has been changed to "vulnerable". In Victoria, the koala is not on the threatened species list at all, and in some protected and remote regions, there is actually an overpopulationproblem.
Despite urging by conservation groups since around 1992, Australia's federal government has not yet listed the koala as vulnerable, except in certain areas. Even international conservation groups cannot agree. Meanwhile, the International Union for Conservation of Nature (IUCN) lists the koala as "potentially vulnerable", while the US Endangered Species Act lists the koala as "threatened".
How many animals become extinct every minute wiki?
I saw a movie in a science class, and it said every 20-30 minutes.
A species that is in danger of becoming extinct. There are low numbers of the animal and they may not be able to reproduce fast enough to survive as a species. Or they may face some environmental factor that is causing them to not reproduce enough to survive.
What is the first ancestor of the horse?
Kalobatippus Merychippus PlesippusDinohippus More including the ones listed above can be found at the below link:http://en.wikipedia.org/wiki/Evolution_of_the_horse
How does mass extinction effect species that survive?
animals that depended on a species for a food source or some other need will not be able to get that need if that species is extinct, and will either have diffuculty surviving, or will go extinct.
How do you know about the megalodon?
Even though you cannot find ancient shark skeletons because the cartilaginous skeleton decomposes(under most circumstances), you can find their teeth. Scientists have found teeth from megaladons, and by comparing the teeth to body ratio of existing sharks today, they can estimate that megaladon was the largest known shark that ever lived.
No one knows. They are extinct. You can't know about behavior from fossils no matter what paleontologists say. Assumptions about feeding can be made but without a living specimen to verify the assumptions, they are just shots in the dark.
