Dinosaur Deaths:

(SFX: under here. . . falling large thumping object)
SIXTY-FIVE MILLION YEARS AGO A GIANT METEOR CRASH LANDED IN MEXICO.  THE
DINOSAURS ALL DIED 
(SFX: many thumping objects) 
SHORTLY THEREAFTER, SO MANY SCIENTISTS THINK THE TWO EVENTS WERE
CONNECTED.  BUT HOW? A TEAM OF SCIENTISTS RECENTLY SET SAIL ONBOARD THE
"RESOLUTION" TO SEARCH FOR CLUES.  THE RESOLUTION IS AN OCEAN DRILLING BOAT
THAT LITERALLY DRILLS INTO THE SEA FLOOR. OCEANOGRAPHER HAROLDUR
SIGGURDSON AT THE UNIVERSITY OF RHODE ISLAND SPOKE FROM THE BOAT ABOUT
THEIR RESEARCH,
     "We're drilling in the carribean. . . to study the sedimentary records. . . we dril linto the sea floor. .
. over a mile in some cases, in order to extract . . . solid pieces of rock from the ocean floor."
       SIGGURDSON EXPLAINS THAT THE METEOR SENT UP A HUGE DUST CLOUD THAT
SETTLED OVER THE EARTH.  THIS DUST HAS LONG BEEN BURIED UNDER THE OCEAN
FLOOR, BUT THE SHIPS DRILL CAN BRING SOME OF IT BACK UP TO THE SURFACE.  BY
STUDYING 65 MILLION YEAR OLD SEDIMENTS, HE HOPES HE CAN FIGURE OUT WHAT
EFFECTS THE METEOR HAD ON THE ENVIRONMENT.  
     "We believe that the very large cloud of sulfur rich gases enveloped the earth and. . . formed a thin
veil in the atmosphere. . . in turn causinga cooling of the earth's surface, and this cooling was sufficiently
severe. . .to cause a very sudden. . . climate change and also total darkness for extended periods. . . and in
turn leading to a collapse of the biological system including the extinction of the dinosaurs."
     SIGGURDSON WOULD ALSO LIKE TO FIGURE OUT WHAT WOULD HAPPEN IF
ANOTHER METEOR HIT THE EARTH.
     "Fortunately they only happen at the rate of about once every 100million years."
