Dinosaurs lived 200
million years ago.
Dinosaurs have been
dead for 60 million
years. People have
only been on our earth
for 6 million years.
4.
Cretaceous dinosaurs
were the last
dinosaurs on earth.
There were more
dinosaurs during this
period than all the
other periods put
together.
6.
Cretaceous dinosaurs
lived for 80 million
years. The weather
was like our weather
today. The summers
were hot and the
winters were cold.
Then, about 65 million
years ago, dinosaurs
all mysteriously
disappeared forever.
8.
Some dinosaurs alive
at this time were the
Triceratops,
Velociraptor,
Saltasaurus, and
Ankylosaurs. Also
alive was the
Tyrannosaurus.
10.
Triceratops had a
three- horned face and
a beak to feed on
plants. It was 30 feet
long and 10 feet high.
12.
Velociraptors were
carnosaurs or meat
eating dinosaurs. They
ate the plant eating
dinosaurs. Their
sharp pointed teeth
were their weapons
for tearing apart their
food.
14.
Saltasaurus was a
huge plant eating
sauropod or large
lizard. It walked on
four thick legs and
had a long neck. It’s
pencil thin teeth cut
leaves high over head.
Its stomach had stones
to crush and grind the
leaves.
16.
Ankylosaurs moved
slowly and had a small
brain, but had great
protection from their
enemies. Thick bony
plates and spikes cover
their backs and sides.
They also had a club of
solid bone on the tip
of their tails.
18.
Tyrannosaurus was
the largest meat-eater
of all time. It had seven
inch long sharp teeth
and weighed more
than an elephant.
Tyrannosaurus could
have been 18 feet high
and 50 feet long.
20.
The end of the
Cretaceous period was
the end of all
dinosaurs. Why did
they disappear? Was
it a change in climate
or loss of food? Was it
a terrible disease?
What do you think
caused the end of the
dinosaurs?
