There have been many mass extinctions throughout the history of the Earth. Probably the most famous is the extinction that finally saw the end of the dinosaurs reign on the Earth, 65 million years ago. It wasn't just the dinosaurs that died out in this extinction. Whatever caused the death of the dinosaurs also caused the death of around 70% of all of the species on the Earth. Although the dinosaurs had been in a period of decline, it is thought

Peripatus: Extinction
New Zealand

A number of extinction concepts are discussed and loosely defined, followed by a survey of some important extinction and "extinction-like" events, primarily from the Phanerozoic. The idea of individual species becoming extinct is quite familiar; indeed it is a rather sad indictment of our stewardship of the planet that we are all too familiar with extinction. But, in fact, extinction is a rather complex phenomenon. At one end of the continuum

Extinction of the Dinosaurs
United States

Perhaps the most notable event of the Cretaceous was its conclusion. About 65 million years ago the second greatest mass extinction in Earth history occurred, resulting in the loss of the dinosaurs as well as nearly 50% of all the world’s species. Though not nearly as severe as the end-Permian mass extinction, the end-Cretaceous extinction is the most famous mass extinction in Earth history. Regardless of what caused the disappearance of the

The Dinosaur Origin and Extinction
Denmark

The dinosaurs originated from diapside reptiles which survived the mass-extinction at the end of the Permian as swimming archosaurs. From those emerged bipedal archosaurs, among others two groups of bipedal hervivores, the short-necked ancestors of the ornitischian dinosaurs, and long-necked ancesors of the saurischian sauropods. Later emerged the short-necked meat-eaters, ancestors of the carnosaur dinosaurs. From a lineage of small bipedal, tre
