Extinct Animals

Trilobites originated during the Cambrian era, flourished through the Paleozoic era, declined during the Devonian era, and finally became extinct in the Permean mass extinction event.

In total there were live trilobites on the earth for about 290 million years.

According to WWF;

1.Black Rhino

2.Giant Panda

3.Tiger

4.Beluga Sturgeon

5.Golden Seal

6.Alligator Snapping Turtle

7.Hawksbill Turtle

8.Big Leaf Mahogany

9.Green-Cheeked Parrot

10.Mako Shark

There also is the Komodo dragon because of the fact there is only 40 breeding females. there is no eight because some one put a big leaf mahogany which is an tree not an animal

There are several such lists, and many animals in more danger than those listed above. Examples are: Cuban crocodile, Grenada dove.

#1: Ivory billed woodpecker#2: Amur leopard#3: Javan rhinoceros#4: Northern sportive lemur#5: Northern atlantic right whale#6: Western lowland gorilla#7: Leatherback sea turtle#8: Siberian tiger#9: Chinese giant salamander#10: Either Tooth-billed pigeon or Kapako parrot

Here are some close to this list:

.Greater bamboo lemur.Mountain gorilla.Hawaiin monk seal.Axolotl.White lion

There are too many humans encroaching on the bears habitat. With the growth in human population (over population) all other animal species that cannot live with humans are threatened with extinction, not just bears

The saber tooth tiger is usually about 4 to 5 feet long and 3 feet tall. It weighed about 440 lbs which is about 200 kg.

This is answers.com, not the psychic network.Nobody knows. Various people have predicted various things, but until one of them happens, we won't know for sure.

At one time it was believed that mass extinctions were periodic, and some analyses suggested we were about due for one ... but as more data has come in, it now looks like the periodicity may have been a statistical coincidence, and that smaller extinction events occur all the time. There was a relatively recent one in the oceans about two million years ago, for example (the last really major one was the K-Pg event 66 million years ago, widely thought to have been caused by an asteroid impact).

the idea that extinction evedince is a natural event

1. Kiwi - Small flightless bird
2. Dodo - Larger flightless bird
3. ?

Humans have contributed to the extinction of animals and plants by over hunting/over harvesting since the beginning of man. Sometimes the over hunting that man did also contributed to the extinction of plants because the animal that man hunted was required by the plant or it's seed to reproduce.

The Moa lived in parts of New Zealand, which the Maori used to hunt them, kill them and eat them.But nowadays the flightless Moa is extinct.

The cat was responsible for killing the dodo birds. it was taught that the last group of dodo birds lived around a lighthouse it was soon found that the cat had eaten every dodo bird left. but it was only one.

it is impossible to answer this question as they live in dense jungle and are constantly breeding

Titanis Walleri. This bird is known from the early Pleistocene (Ice Age) of Florida. It is the last known member of the family Phorusrhacidae, a group of large, flightless birds which evolved in South America. This creature had an estimated body height of 3 meters (if it stood fully erect, and 2.5 meters in more normal situations). Titanis really had arms instead of wings.

There were many types of elephant like animals that went extinct. Some didn't look like the elephants we have today. The Moeritherium looked much more like a hippo or tapiar, but was a relative of modern day elephants. There were also the mammoths, mastodons, and several other species that had shovel like tusks on their bottom jaws.

A species who cannot adapt to its environment, cannot survive. Adaptations have kept species from being extinct. Adaptations can include, changes in diet, development of protection such as fur coats against temperature, and even skin color changes to act as camouflage from predators.

The Eohippus became extinct in the mezozoic era (middle age era).

It became extinct because of the climate changes and the struggle to survive. Then it changed into a Miohippus after milions of years.

Animals rely on habitats because each creature has a body structure that must have a specific diet and climate. This is why some creatures are not seen in other parts of the world.without their habitat they would die.

They browsed through coarse arctic grass as an elephant would. You're welcome.

Plant life cannot survive without animal life in the world anyway, because plants give out oxygen to the animals because animals need to breathe in order to live. Animals let out carbon dioxide which plants take in, and the cycle repeats.

that the animal once had a use for that structure depending on where it lived. or that it decended from an animal that had that structure and used it.

2000 pounds is the weight of a full grown cheetah.

Orangutans are now considered to be the smartest of the primates, over chimps. Orangutans have been taught to saw wood, use a hammer to nail structures together and even siphon liquids through a hose. But while that could be simply marked up to rote training, what makes the orangutan smart is its ability to understand why we complete these actions and use them in the wild when they might be helpful. For example, an orangutan was taught how to build a simple protective structure using tools available in the wild. When released from captivity, the orangutan was observed building the same structure to get out of the rain.

Allsirenians are and were vegetarians. The Steller's Sea Cow falls under the category of Sirenia and therefore, they were, before they were hunted to extinction, vegetarians.

They became extinct in the mid-1800s as a result of human exploitation. Men not only massacred the birds for food, they also gathered the eggs of the auk to supplement their diets. The islands where they had nested remain largely uninhabited by humans.
