Tiny Shelled Creatures Shed Light on Extinction and
Recovery 65 Million Years Ago, Science Daily, March 1, 2010

?An asteroid strike may not only account for the demise
of ocean and land life 65 million years ago, but the
fireball's path and the resulting dust, darkness and
toxic metal contamination may explain the geographic
unevenness of extinctions and recovery, according to
Penn State geoscientists.?
