Pronunciation:
FAL-car-EE-us
Falcarius belonged to the group
of dinosaurs that were meat-eaters.
But unlike its relatives, Falcarius ate
mostly plants. It used long, curved
claws to rip up plants and pull down
branches to eat. Feathers covered
this dinosaur and kept it warm.

Suuwassea was a long-necked
plant-eater. At 40 feet (12 meters)
long, this dinosaur was big, but it
lived among relatives that were
even bigger. Suuwassea moved,
fed, and slept in herds. It was
always on the lookout for
predators seeking an easy kill.

Suuwassea did long ago.

Acrocanthosaurus was a hunting
dinosaur. It chased smaller prey in
forests and along beaches. Unlike
other predators, this dinosaur had
a low, patterned sail down its back.
The patterns may have helped
Acrocanthosaurus hide among
plants and rocks.

Acrocanthosaurus kept a

and small meat-eaters to
hunt and eat.

Pronunciation:

Stegosaurus was a plant-eating
dinosaur. It had plates down its back

The plates protected the Stegosaurus

spikes as weapons.

But unlike the Barosaurus, it
cannot rise on its hind legs.
