The Palisades cliffs west of New York City rear up from the Hudson River like the spine of some ancient beast—and that impression is not far off. Their basalt backbone is a remnant of an immense lava ...

There have been five unquestionably great extinctions on earth: the end-Ordovician, the late-Devonian, the end-Permian, end-Triassic, and the end-Cretaceous extinctions. Some think we are now in a ...
