Cretaceous Period
The Cretaceous period was the final of the three periods into
which we divide the Mesozoic Era (the previous periods being
the
Triassic period,
and the
Jurassic period),
and occured between 144 million and 65 million years ago.
Many well-known types of dinosaurs
lived during the Cretaceous, including
Ankylosaurus,
Iguanodon,
Pachycephalosaurus,
Protoceratops,
Spinosaurus,
Styracosaurus,
Triceratops,
Tyrannosaurus rex, and
Velociraptor.
It was also during the Cretaceous period
that the first flowering plants
("angiosperms") began to appear, including, for example,
beech, fig and magnolia.
At the end of the Cretaceous period (known as the K-T boundary), dinosaurs, and
and a variety of other animals all suddenly became extinct.
There have been many theories proposed for why this
mass extinction
occured.
Here is a map of the world in the late Cretaceous period.
You will notice that the continents have begun to move towards
their present positions (movements which continued into the subsequent Tertiary era),
with the Atlantic Ocean opening up between Europe and North America, and India
continuing its long journey Northwards.
The Cretaceous world was cooler than it had been in the
previous
Triassic
and
Jurassic.
periods, but still warmer than that of today.
At higher latitudes snowfalls became common, although the climate generally
remained warm even at such latitudes - glaciation was
restricted only to alpine regions in high latitudes.
Meanwhile, tropical parts of the
globe were much wetter than they had been previously.
