Tyrannosaurus
Tyrannosaurus Rex was a
fierce predator that
walked on two powerful
legs. This meat-eater had
a huge head with large,
pointed, replaceable teeth
and well-developed jaw
muscles. It had tiny arms,
each with two fingers.
Tyrannosaurus Rex was
up to 40 feet
tall.www.itsnature.org
Name means tyrant
reptile. (King)
Brontosaurus- Apatosaurus
It has also been called
Brontosaurus (thunder
reptile) but the name
Apatosaurus was
given first. When fully
grown it weighed
about 30 tons! It
therefore spent a
great deal of time in
the water which
helped support its
immense weight. They
could live to be about
200 years old.
Brachiosaurus
• Brachiosaurus was one
of the tallest and largest
dinosaurs yet found. It
had a long neck, small
head, and relatively
short, thick tail.
Brachiosaurus walked
on four legs. Its front
legs were longer than its
hind legs. These
unusual front legs
together with its very
long neck gave
Brachiosaurus a giraffelike stance and great
height, up to 40-50 feet
tall.

Triceratops
Name means three horned
face. Triceratops had a bony
frill to protect its head, neck and
shoulders. It's head was
enormous, nearly a third as
long as its whole body. Its
curved jaw was very strong and
like a parrots beak. Although it
was a plant eater it was very
fierce - even fighting with its
own kind. Triceratops is the
best known horned dinosaur. It
had three horns: one on its
nose and two long ones above
its eyes.
Allosaurus was a
large carnivorous
dinosaur, which had
a very large head,
which was balanced
only by his very long,
very heavy tail.
In what is now the
United States,
Allosaurus was the
largest common
predator dinosaur.
It lived about 100
million years ago, in
the Jurassic period
of Earth.
Allosaurus
Albertosaurus
• It was smaller
than
Tyrannosaurus,
but still a
fearsome beast
• Name means
Alberta reptile
(discovered in
Canada)

Diploducus
The term 'double beam'
refers to a special feature of
diplodocus' backbone. There
were small bones below the
backbone which had a piece
running forward as well as
the normal piece that runs
back - a 'double beam'.
Diplodocus was the one of
the longest dinosaurs, it was
about as long as a tennis
court. Its brain was about
the size of a hen's egg
Name means double beam

Stegosaurus
• Name means roofed
reptile
• The Stegosaurus had a
very unique row of plate,
or ridges that rose from
his back in two separate
rows, and long spikes at
the end of his tail.
• He was an herbivore, and
could have eaten massive
amounts of leafy greens
during the course of a
day, perhaps as much as
his own body weight in
food.

• Ankylosaurus was a huge
armored dinosaur, measuring
about 25-35 feet long, and 4
feet tall; it weighed roughly 3-4
tons. Its entire top side was
heavily protected from
carnivores with thick, oval
plates embedded (fused) in its
leathery skin, 2 rows of spikes
along its body, large horns that
projected from the back of the
head, and a club-like tail. It
even had bony plates as
protection for its eyes. Only its
under-belly was unplated.
Flipping it over was the only
way to wound it.

Ankylosaurus
Oviraptor
• Name means
egg thief
• It had a short
head and a
powerful
toothless beak.
The jaws were
curved so that it
could crush very
hard objects.
Velociraptor
• The Velociraptor
was a very fast
moving biped
dinosaur.
• It was a meat
eater, who could,
according to
scientists, outrun
anything it came
near.
• The Velociraptor
had over eighty
very thin and
sharp curved
teeth, which
were well over
an inch long.

Five Enormous Dinosaurs
Poem from: www.Preschoolfunzone
PowerPoint by Jeanne Guichard
Five enormous dinosaurs
Shouting out a roar;
Along came an alligator
Then there were four.
Four enormous
dinosaurs
sitting in a tree;
‘Til the wind blew by,
Then there were three.
Three enormous
dinosaurs
were taken to the zoo;
‘Til one got away,
Then there were two.
Two enormous dinosaurs were
having such fun;
‘Til a volcano blew up,
Then there was one.
One enormous dinosaur,
He must of weighed a ton;
‘Til the lakes dried up
Then there were none.
