Exact Age of Dinosour :D by Sumita 2013/02/08 05:27
Some tourists in the Chicago
Museum of Natural History
are
marveling at the dinosaur
bones. One of them asks the
guard,
Can you tell me how old the
dinosaur bones are?
The guard replies, They are
three million, four years, and
six months old.
Thats an awfully exact
number, says the tourist.
How do
you know their age so
precisely?
The guard answers, Well, the
dinosaur bones were three
million years old when I
started working here, and
that was
four and a half years ago!
