Well i am sure most of the cat family is going extinct, but have not yet. While I am on the subject people need to save tigers and other cats in the world that are dying out. It is people that are killing their kind, what if you were the tiger and they were the one killing us, how would you feel about that. How would you feel if you were the one in the cage, or being separated from your family. What if your child can't even go to the zoo and see the wonderful animals like tigers, cheetahs, bob cats, mountain lions, or can't even have a house cat like you have at home with you right now, just think one after another, soon all cats and other animals will be gone. SO GO OUT AND FIGHT FOR THE RIGHTS THAT THESE ANIMALS HAVE....

What event occurred about 250 million years ago and caused about 90 of the species living in the ocean to become extinct?
The Permian-Triassic mass extinction, aka "the Great Dying", the single most devastating mass extinction known.
How much time must pass before a species is considered extinct?
It actually doesn't matter the length of time. When the last animal of that specific species is dead, the the animal is proven to be extinct. Sometimes animals are thought to be extinct, then are re discovered, as the case of the ivory billed woodpecker in the U.S. It usually takes many years after the last sightings of an animal before it is declared extinct. In some cases the last known animal of a species is in a zoo so when that animal dies the species will be declared extinct. This was the case with the passenger pigeon which was hunted to extinction in the early 20th century. The last passenger pigeon died in the Cincinnati Zoo in 1914.
What event occurred about 250 million years ago and caused about 90 percent of the species living in the ocean to become extinct?

Why does extinction matters?
Extinction matters because each species is a work of art, a masterpiece of nature produced by millions of years of evolution, so we should do our best to preserve them before they go extinct. They have a right to exist on this Earth just like we do.
Whats are the causes of extinction?
An animal might be hunted into extinction. Some of the last Australian thylacines were shot to death, though the very last one probably died in a zoo. The passenger pigeon was hunted into extinction. Disease can also wipe out a species. The Tasmanian devils are threated by a face cancer. An asteroid (or comet) impact may have wiped out the dinosaurs 65 million years ago. If an animal's food source becomes extinct, or the animal is driven from a key food source, that can cause it to become extinct. Competition for a food source can also lead to extinction, for example, if some other species devours all the food. It was once thought that the dinosaurs may have become extinct because little mammals ate all their eggs. Invasive species may step up competition for resources, driving native species to extinction. Also, extinction may be caused by a combination of these factors.

Why the huayangosaurus went extinct?
huayangosaurus went extinct in the K/T Mass Extinction in 65 million years ago with all Dinosaurs Went Extinct
How does the background rate of extinction differ from mass extinctions?
The background rate of extinction is much smaller than those that occur during a mass extinction. For example, carnotaurus sastrei went extinct during the mid-Cretaceous, when only a handful of dinosaurs went extinct. On the other hand, 65 million years ago, all dinosaurs went extinct during the K/T mass extinction event.
