Then you're in luck, because the “eleMMent Palazzo,” the world's most expensive motorhome, is for sale in Dubai. This is a book about the dramatic periods in the Earth's history called mass extinctions - short periods (by geological standards) when life nearly died out on Earth. Here wandered also the “mammal-like reptiles” who once dominated, nearly died out in an even more encompassing extinction event 250 million years ago, recovered, grew huge then suffered in mass extinction that ended the Triassic. The next great extinction was in the Late Devonian (≈364 Mya), when 22% of marine families and 57% of marine genera, including nearly all jawless fishes, disappeared. The giants among the mammal-like reptiles A two-hour jaunt to the Petrified Forest from Payson lays bare all the great questions – fate and creation and the blind and heroic persistence of life. Some species are more critical than others in preserving the It is best known for the extinction of non-avian dinosaurs, but large numbers of plant species also became extinct at that time. And while the end-Permian mass extinction may have been nature's greatest failure, new evidence shows its recovery was even more impressive than we thought. The Earth is now entering the sixth mass extinction event in its four-billion-year history, but what's different about this die-off is that this is the only such event precipitated by a biotic agent: humans. Santa Barbara, California - The sixth mass extinction of both plants and animals is underway, scientists say, warning that nearly 50 percent of all species could disappear within the lifetimes of people now living on Earth. If you are so fabulously wealthy that you can drop a cool $3.1 million on the vehicle, why not broadcast it to the world? Feverishly hot ocean One key factor behind this disaster was probably catastrophic volcanic activity in what is now Siberia that spewed out as much as 2.7 million square miles (7 million square kilometers) of lava, an area nearly as large as Australia. (Or, at least, the highway.) The gold color will definitely Pat Buchanan: 'What is all this nonsense about bringing people out of the shadows?' 10 strange hobbies people actually spend time doing [SLIDESHOW]. After all, new species arise and old species die off all the time. Scientists have found the hottest temperature the planet has ever experienced may have helped cause the greatest die-off in history at the end of the Permian Era some 250 million years ago. One of the most dramatic and mysterious events in the history of life, the so-called “Great Dying” of animals and plants some 250 million years ago, continues to fascinate and baffle scientists. Slithering in at 48 feet long and weighing an estimated one-and-a-half tons, the largest snake the world has ever seen is being brought back to life. A recent study supported by The National Science Foundation and National Institutes of Health, found that nearly all of the amphibian species that inhabit the peaks of the Sierra Nevada are threatened. Newitz, a science journalist and founding editor of the Web site io9, set out to write about the looming disaster of the sixth mass extinction but instead found hope for humanity's endurance.
