What we can learn from the biggest extinction in the history of Earth

Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences at Stanford University.

1. Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
   03-28-2007 · EurekAlert!
   A new, complete "tree of life" tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.

   Topics include: global climate change and biotic recovery following the end-Permian mass extinction; evidence of warming during the Neoproterozoic; new insights into structure and dynamics of the San Andreas fault; origin of some of Earth's largest natural crystals; and discovery of Martian rock layers that illuminate the planet's hydrological history. The GSA Today science article addresses relationships between Northern Cordilleran terranes and tectonic evolution of western North America.

3. Meteor no longer prime suspect in great extinction
   10-24-2007 · EurekAlert!
   New study looks to the deep ocean for cause of history's biggest extinction (NOT the one that killed the dinosaurs). Taken with other studies, evidence does not support meteor theory for this extinction.

4. New theory for mass extinctions
   10-24-2006 · EurekAlert!
   A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter. Whether you favor meteor impacts, volcanic eruptions, cosmic rays, epidemics or some other cause for the worst mass extinction events in Earth's history, no single cause has ever satisfied all scientists all the time for any extinction event. That may be because big extinctions aren't simple events.

6. Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
   11-23-2006 · EurekAlert!
   The biggest mass extinction did more than eliminate species: It fundamentally changed the basic ecology of the oceans. Ecologically complex marine communities displaced simple communities, setting a pattern that has continued ever since.This striking change has escaped detection because previous research relied on single numbers -- such as the number of species alive at one time -- to track diversity. New research examines the relative abundance of marine life forms in communities over 540 million years.

    11-23-2006 · EurekAlert!
    Earth's interior is not a benign world that only stores the geologic history of our planet. Geologists now see the inner Earth as a dynamic environment filled with exotic materials and substances roiling under intense heat and pressures. The latest evidence of this dynamic inner Earth is revealed in a recent series of measurements that peered deep within Earth, halfway to its center.
