Dinosaurs were reptiles
which lived m
illions of years
ago, long before there were
any people
.
Dinosaurs lived on the
earth for over 1
00
million
years but then they
mysteriously became extinct
.
There were lots
of different kinds of
dinosaurs that lived
at different times.
Some were
HUGE……
… and
the other
were much smaller
.
Some dinosaurs could
move along quite quickly on
two legs.
Others walked on four
legs in a very slow and
clumsy fashion.
