Extinct Animals

Well, sometimes things have to go so new things can grow. Or that there isn't a habitat available for the certain species and they have to move on.

Shells are a kind of external skeleton

The shells grow by adding new material to the edges as the animal inside gets bigger in this way the animal is protected by its shell all the time and does not have to moult or shed their shell.

Saber-toothed animals included the gorgonops, machaeroides, uintatherium, smilodon, and the gomphotaria. The most famous of these is the smilodon, commonly called the saber-toothed tiger.

I think it is the study of animal behavior.

No, an Archaeopteryx is a prehistoric bird, while a Phoenix is a mythical bird. Archaeopteryx was not discovered until 1861, while the myth of Phoenix was referred to as early as 170AD. Those who would try to link the two in any way will also be disappointed, as Phoenix was described as very large, while the largest of the Archaeopteryx specimens was only about the size of a magpie.

what are the disvantages of animal extinction

yes but it is not the biggest living organism in the world!

The dragons were driven up to the caves by humans after the last ice age. The ice age had already happened before they were driven up. After the KT event, the earth was almost completely wiped out but only the animals that took to the water survived. The land dragons were extinct but still some of the water dragons survived, and over thousand of years, evolved to walk back on land. It's possible some dragons did live up in the mountains during the ice age, and if so they had a number of ways of surviving. first of all they lived in caves with kept the heat in like an igloo. Second, dragons have a protein in their body that keeps their skin from freezing. If they eat enough, they can also hibernate for many days and beat out most of the cold. they also have fire, but must use it cautiously because they do not have an endless supply. Hope this answers your question and if you have anymore you can watch the movie "dragon's world" and find out some answers.

It had long brown and greyish feathers,with brown legs and feet. so it was mostly a brown colour.

There are many advantages and disadvantages of email. Email is very quick and dependent but is less personal for example.

Mainly because, nature hates a vacuum. When a certain species drops in numbers, often another, similar species takes over the niche vacated. A good example is the northern spotted owl. As its numbers declined, a close relative, the barred owl, has became more common in the Northwest, displacing the northern spotted owl in many areas.

There are several factors that contribute to plant extinction. Climate change, acid rain, animal extinction, deforestation, and declining honey bee populations all contribute to plant extinction.

They're still around now.

The "Burning Tree Mastodon" was discovered in 1989 near Hebron, Ohio, in Licking County, while dredging a golf course pond which also happened to be a pre-historic bog. The mastodon was found missing a rear leg but otherwise fully intact- including stomach bacteria which was suspended by the bog chemistry and was the oldest known living organism at that time. There were stone tool cutting marks on the mastodon bones which remained, but there was no evidence that humans killed the mastodon- only that they butchered part of it. Humans hunted mastodon in Ohio so it is certainly possible humans killed it. It was likely preserved intentionally in the bog but the owners never returned to claim the rest of the meat.

they were omnivores so they were able to eat plant and animals but they enjoyed eating land snails

The Tasmanian wolf or Tasmanian tiger, also known as the thylacine, is an extinct marsupial carnivore. The thylacine was exclusively carnivorous. For more information on the diet of the thylacine, click on this link.

A Cat Bus is an extinct animal from the movie 'my neighbour totoro'. It is a giant cat that lets people ride in it therefore it is a cat bus. It looks like a bus but also a cat. The only word it has ever said is 'Mei!!'. It is ginger. Its best friend is Totoro.

The largest cats to have evolved are normally consideres to be the large American lion where from all the sources I've seen range from 380 KG to a stunning 500 KG meaning that by some distance they are quite large compared to any modern day Cats probably comparable to Ligers in size. The phenotype denotes that they were quite similar in appearance to modern day African lions, but just on average larger and with minimal manes similar to modern day tsavo lions, the reason their appearance is so vividly described compared to other extinct cats is due to their almost perfectly preserved fossils from the la brea tar pits in California. One particular source states that it was more closely related to Tigers than lions which I don't realy believe to be true due to the fact that the only reason for such a comparison is the skull, the Panthera atrox actually morphologicay is still more similar to Lions than tigers. When it comes to evolution the The American lion seems to have an intermediate between the lion/leopard and jaguar lineage meaning that it was a powerful cat having something of a lion- jaguar like build (pound for poumd jaguars are the strongest cats). they eventualy died out probably due to competition from smaller carnivores that required less energy to sustain their existence i.e cougars which remains the case with most of the larger mamals of north America like the giant short faced bear that was eventualy replaced by the brown bear, they were simply to big and could not be sustained in the ecosystem. other factors include hunting from paleolithic American Indians and the megafauna extinction at the end of the ice age.

The other large powerful cat from this similar time was the Smilodon populator of south America. Smilodon populators size also varies from Tiger sized to a size similar to the American lion (although the heaviest specimen is now at a more refined estimate of 400 KG than the previous thought 500 KG), although they were shorter (lions are generaly the tallest extant cats with modern day lions being taller than tigers) but more robustly built. the most popularized description of them is being bear like lions due to their imense muscular build as their main method of hunting was simply wrestling its prey to the ground so as to get a clean bite. though it had longer canines than the American lion it also had weaker jaws as the jaws of these cats were not evolved for power but rather precision unlike the pantherines sometimes known as biting cats who have a significant force behind those shorter caninnes. the main reason for this can be said to be the evolution, the large canines of smilodon meant they were fragile and thus to be effective a longer snout was required which meant the zygomatic arches of this cat were smaller thus meaning at best it only had the biting force of a third the strenghth of a modern day African lion. This is quit interesting as the saber tooths with the longest canines often had the weakest bites. But in order for those jaws to be effective the cat had immense muscular strenghth simply to just pin down the prey as most of its prey was larger than itself meaning that it was incredibly powerful and could easily be the strongest cat to have evolved.

Latin is the former language of which the words manicure and pedicure are derived from. A manicure is a beauty treatment for the nails of the hands and a pedicure is a beauty treatment for the nails of the feet.

No. Pterodacyls and pteranodons were two different types of pterosaur.
