A hundred million years from now, when were all dead and gone, a team of geologists will be digging in a field somewhere ... ... and they will discover, buried in the rocks below, a thin layer of sediment — very thin, about the width of a cigarette paper, says British stratigrapher Jan Zalasiewicz. That skinny strip, when they look close, will send whats called a biostratigraphic signal that something enormous happened back in our era, something life-changing, planet-reorganizing, even Earth-shaping. The evidence, when they look closely, will be visible in that same skinny layer all over the world. wgbhnews.org/post/planet-earth-under-new-management
