Small and
Fierce
Imagine a dinosaur on the
hunt. You may picture
a giant taller than a
building. But not
all dinosaurs
were big.
How big do
you think this
Deinonychus was?
Velociraptor and Deinonychus
were small dinosaurs. They
were shorter than your
parents! But they were fierce
predators.
Predators hunt
other animals.
Velociraptor was
small but dangerous.
These dinos ran on two legs.
Long, stiff tails helped them
balance. They bit with strong
jaws. Sharp teeth tore meat.
A tail balanced
the weight of this
dinosaurs head.
Raptor comes
from a word that
means capture.
Velociraptor and Deinonychus
were dinosaurs called raptors.
Raptors had large hands with
three big fingers. They used their
hands to grab prey.
Prey is an
animal hunted for food.
Look at the raptors feet. Each
foot had one extra- large
claw. The dinos raised this
claw when they walked. The
sharp claw was a weapon. It
probably pinned down prey.
Deinonychus means
terrible claw. The name
comes from the huge
claws on this dinos feet.
You can tell these hunters
apart.
Deinonychus was
larger than Velociraptor.
It was to feet (about
meter) tall.
With its tail, Deinonychus was
about feet (3 m) long.
Velociraptor was not as big.
It was only a little taller than
a turkey! It stretched about
feet (2 m) from head to tail.
On the
Hunt
How did Velociraptor and
Deinonychus find food?
They followed the smell of
prey. They probably hunted
at night.
Night animals
eyes are shaped
to let in light.
Some scientists think
Deinonychus hunted in groups.
Deinonychus packs may have
attacked larger dinosaurs.
Animals that hunt together
are called a pack.
Deinonychus teeth have been
found with fossils of a much
bigger dino.
Dinosaurs
sometimes lost teeth
when they bit prey.
Scientists do not know if
Velociraptor hunted in packs.
No one has found their fossils
in groups.
An artist drew this picture
of Velociraptors on a hunt.
But no one knows for sure
how these dinos hunted.
Scientists
have found
fossils of hunting
Velociraptors.
They found
a Velociraptor
tangled with
a Protoceratops.
The two dinosaurs
died in battle.
Velociraptors big claw was
buried in Protoceratopss
neck. Protoceratops had
bitten Velociraptors arm.
Velociraptor may also
have been a scavenger.
Scavengers eat dead
animals that they find.
Velociraptor probably scraped
meat from bones with its sharp
teeth. Some Protoceratops bones
have been found with tooth marks.
Feathered
Dinosaurs
Velociraptor and
Deinonychus were
related to birds.
They looked a
lot like birds.
