One reason why the discovery in Australia of the dinosaur footprints is so important is that, ----.
Some 130 million years ago, a spike-backed
dinosaur walked heavily through the wilderness of
what came to be Australia, and left its footprints as a
gift for the future. They were the world's best
impressions of a dinosaur's two-ton footfalls. When
they were found seven years ago in a remote valley
in northern Australia, they provided scientists with the
first clear evidence that dinosaurs had lived in
Australia. This discovery provided further evidence
for the theory that Australia was once joined to a vast
super-continent that included what is now South
America, Africa, India and Antarctica.
