Siberian Volcano extinction

     I found this article in this morning's San Jose Mercury News 
     (Sept 8, 95)
     (available through Mercury Center on the Internet (N631)
     (no author or source given)
       A volcanic eruption that lasted a million years and flooded Siberia 
     with lava a mile deep may have killed 80 percent of the world's 
     animals-an extinction far more deadly than the later one that claimed 
     the dinosaurs, researchers conclude.  Precise dating of geologic 
     samples that mark the extinction 250 million years ago show the 
     massive die-off occurred at about the same time a volcanic eruption 
     blanketed Siberia with lava and filled the sky with chemicals, 
     scientists report today in the journal Science.
