Facts, Theories and News About Dinosaur Extinction
We know that the dinosaurs went extinct 65 million years ago, but precisely how (and how fast) this happened is still a matter of dispute. Here's everything you know about current dinosaur extinction theories.
10 Myths About Dinosaur Extinction
Scientists have a pretty good idea why the dinosaurs went extinct--but that hasn't prevented some popular myths from spreading about how, when, and even whether dinosaurs went down for the count. Here are the top 10 misconceptions about dinosaur extinction.
The K/T Extinction Event
The prevailing view among scientists is that the extinction of dinosaurs 65 million years ago was caused by a meteor impact on Mexico's Yucatan peninsula--which spread clouds of dust around the earth that blocked the sun. Here's what we currently know about the K/T Extinction Event.
Did the Dinosaurs Really Go Extinct?
Cryptozoologists believe the world may still harbor living, breathing dinosaurs--for example, the Loch Ness Monster is often adduced as a marine reptile or aquatic sauropod. Here's a peek into the reasoning of these "experts", and why they're almost certainly wrong.
The Permian-Triassic Extinction Event
About 250 million years ago, at the end of the Permian period, over 90 percent of the earth's marine organisms went extinct, along with nearly three-quarters of terrestrial species. What was the cause of this "Great Dying?", and what effect did it have on the ensuing Triassic period?
Why Did Crocodiles Survive the K/T Extinction?
Sixty-five million years ago, dinosaurs, pterosaurs and marine reptiles were wiped off the face of the earth by the K/T Extinction--while their close cousins, the crocodiles, managed to survive this global cataclysm and prosper into the Cenozoic Era. The question is, why?
Did Volcanoes Kill the Dinosaurs?
Most scientists believe that a meteor impact 65 million years ago killed the dinosaurs--but that hasn't kept a respectable fringe from claiming that volcanoes were actually responsible for the deed. Did volcanoes, rather than meteors, cause the K/T Extinction?
10 Recently Extinct Game Animals
Hunting has been a human pastime since the dawn of civilization--and, not surprisingly, the spread of civilization has been accompanied by the extinction of various game animals. Here are 10 deer, elephants, bears and hippos that have gone extinct in historical times.

Why Do Animals Go Extinct?
What are the factors that cause a plant or animal to go extinct--not only in the present day, but hundreds of millions of years ago? Here are the 10 most common causes of species extinction.
The Top 10 Candidates for De-Extinction
De-extinction is the process by which scientists hope to clone long-extinct animals and reintroduce them into the wild. Here are ten recently extinct mammals, birds and amphibians that are ripe for de-extinction, assuming we can clear the technical hurdles.
De-Extinction - The Resurrection of Extinct Animals
With new advances in DNA technology, it may be possible to "de-extinct" animals that disappeared off the face of the earth hundreds, or even thousands, of years ago. But just because de-extinction is achievable, does that mean we should do it?
De-Extinction in 10 (Not So Easy) Steps
Do you want to know what, exactly, is involved in de-extincting a long-vanished species and reintroducing it into the wild? Here's what the process looks like in 10 easy (or not-so-easy) steps, ranging from harvesting intact DNA to gestating a viable fetus.
10 Recently Extinct Fish
Fish, just like other animals, can be driven to extinction by predation, pollution and changes to their habitat. Here are 10 fish that have gone extinct in historical times.
10 Recently Extinct Shrews, Bats and Rodents
You might think of them as pests and vermin, but shrews, bats and rodents are every bit as important to our ecosystem as larger mammals. Here's a list of 10 pint-sized mammals that have gone extinct in historical times.
100 Recently Extinct Animals
A list of 100 animals that have gone extinct in historical times, including mammals, birds, reptiles, amphibians, fish, insects and invertebrates.
10 Recently Extinct Insects and Invertebrates
The world may be teeming with insects and invertebrates, but that doesn't mean individual species can't go extinct. Here's a list of 10 moths, butterflies, worms and snails that have gone extinct in historical times.
10 Recently Extinct Marsupials
Like other animals around the world, the marsupials of Australia are prone to extinction, usually as a result of habitat loss or predation by invasive species (including human beings). Here's a list of 10 kangaroos, wallabies and wombats that have gone extinct in historical times.
10 Recently Extinct Horses
Although the genus Equus is still going strong, various species (and sub-species) of horses, donkeys and zebras have disappeared during historical times. Here's a list of 10 recently extinct equines.
