A Little-Known Mass Extinction and the "Dawn of the Modern World" - Eos

A new paper promotes a 233 million-year-old extinction event to the status of the five major recognized cataclysms. Situated between the accepted Permian-Triassic Extinction at 250 million BP and the Triassic-Jurassic Extinction around 210 million years ago, the "Carnian Pluvial Episode" (CPE) "was a period of rapid biological turnover on a global scale." Scott Norris discusses how researchers came to this elevated status for the CPE, that it was "a period of new beginnings" just as much of worldwide death, and the likely agency for the change. A Sea Urchin Fossil Found at Mesolithic Site in Bulgaria is enhancing both our concepts of keepsakes and shell-collecting at the same time. Not only that, but the Ohoden Early Neolithic settlement is now recognized to date back to a developmental period 1,000 years previous to what its title implies. But when the Neolithic period was in full swing in southern Britain, New Dates Point to Neolithic Construction Boom. Archaeology asserts a surprising condensed "flurry of monumental building activity" around 2500 B.C.E. (WM)
