The giant fossil mammals that inspired Charles Darwin's theory of evolution - The Natural History Museum


The Natural History Museum
They were to revolutionise his worldview, impacting the naturalist's understanding of extinction, and persuading him of the reality of evolution. His discoveries included four different species of giant ground sloth (some of the largest land mammals ...

Differences in extinction rates drove modern biogeographic patterns of tropical marine biodiversity - Science Advances


Science Advances
Marine biodiversity in the Coral Triangle is several times higher than anywhere else, but why this is true is unknown because of poor historical data. To address this, we compared the first available record of fossil cheilostome bryozoans from ...

The best books about science from the last 15 years that everyone should read - SFGate


SFGate
Over the last 500 million years or so, the world has been faced with five distinct mass extinction events, usually in response to some sort of global cataclysm, like an asteroid strike or intense volcanic activity. In her latest work, Elizabeth Kolbert ...

Peripatus: Extinction

Auckland - 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 we have the notion of a population of organisms evolving into something else. Here, the disappearance of the original phenotype might be accomplished by nothing more than natural turn-over of the generations (anagenesis).

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

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

The Alliance for Zero Extinction (AZE), a joint initiative of biodiversity conservation organizations from around the world, aims to prevent extinctions by identifying and safeguarding key sites, each one of which is the last remaining refuge of one or more Endangered or Critically Endangered species. AZE is first focusing on species that face extinction either because their last remaining habitat is being degraded at a local level, or because
