There have also been other mass extinctions in the geological past, for instance the Permian extinction before the age of the dinosaurs which also wiped out nearly all life 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. However, if even a 'moderate' impact event occurred in 9,500 B.C. The greatest mass extinction pulse was the Permian-Triassic extinction event, and it happened about 250 million years ago, nearly wiping out life on Earth. A mass extinction or extinction event is the phenomenon in which a large number of species of life on Earth become extinct in a relatively short period of time. Unfortunately, his companionless circumstances are not unique. University of Bristol paleontologist Michael Benton has called this event “when life nearly died.” Identifying a mass extinction event is not the same as explaining it, however, and the catastrophe at the end of the Permian is perhaps the most puzzling murder mystery of all time. The resulting direct ultraviolet radiation from the sun would weaken or kill nearly all existing species. When he dies, his genetic lineage will disappear forever. Michael Benton's book about this catastrophe - When Life Nearly Died: The Greatest Mass Extinction of All Time has been published in paperback this week. Michael Benton is Professor of Vertebrate Palaeontology at the University of Bristol. 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. In general usage by scientists, "mass extinction" refers to an extinction affecting a great many different groups of organisms occupying diverse and wide-spread environments.
