Which dinosaur most resembled a rhinoceros? Which had feathers like a

peacock’s?

Questions like these help students develop early classiﬁcation skills based on

the characteristics of the dinosaurs.

Design a Habitat

Challenge students to use crayons and paper to design one of the dinosaurs

in its natural habitat. Make sure the students consider the basic needs of the

dinosaurs including food and shelter.

Animal Act

Encourage students to move and make noise like each of the dinosaurs as you

hold them up in view. Have students take turns acting like a dinosaur and have

others guess which dinosaur the actor is pretending to be. Discuss how the

dinosaurs sound and move in comparison to each other. How are they alike?

How are they different?

Care Instructions

To clean, wipe the surfaces of the dinosaurs with a damp cloth. Dry

immediately. To prevent water from trapping inside the dinosaurs, do not

immerse them in water. Pieces are not dishwasher safe.

Dinosaur Facts

Tyrannosaurus rex

• Tyrannosaurus rex, or T-rex, was one of the largest carnivores (meat

eaters) that ever lived, measuring 40 feet (12 m) long and about 15–20

feet (4.5–6 m) tall.

• Tyrannosaurus rex’s sharp, jagged teeth were useful for hunting. However,

T-rex also had tiny arms that made picking up food very difcult.

• While T-rex is often thought of as a swift predator, paleontologists

(scientists who study fossils) still debate whether it could actually run or

only walk fast. For this reason, estimates of a T-rex’s top speed range from

11–25 mph (17–40 kph).

• Tyrannosaurus rex could eat up to 500 pounds of meat in one bite!

• Tyrannosaurus rex lived in forested river valleys in what is now known as

North America. It became extinct about 65 million years ago.

Brachiosaurus

• Measuring 80 feet (24 m) long and 50 feet (15 m) tall, brachiosaurus was

more than twice the size of tyrannosaurus rex!

• The name brachiosaurus means “arm lizard.” Although brachiosaurus had

no arms, its front legs were much longer than its back legs, giving the

appearance of arms.

• At one time, paleontologists believed brachiosaurus spent most of its time

underwater. However, this was later proved false.

• Brachiosaurus had one of the longest life spans of any dinosaur—many

lived for at least 100 years! By comparison, tyrannosaurus rex had a life

span of only 40 years.

• Brachiosaurus was an herbivore (plant eater) with a big appetite.

Brachiosaurus ate several hundred pounds of leafy greens a day.

Stegosaurus

• Stegosaurus may have looked scary, but it was one of the least intelligent

dinosaurs. Stegosaurus’s brain was about the size of a walnut.

• The name s t e g osaurus means “roofed lizard” because it was once believed

that stegosaurus’s plates were matted ﬂat along its back. More recent

discoveries have conﬁrmed that the plates were actually pointed.

• Stegosaurus was an herbivore. Like many other plant-eating dinosaurs,

stegosaurus chewed small rocks with the plants to help mash down tough

vegetables.

• In 1982, stegosaurus was named the state dinosaur of Colorado after

thousands of fourth-grade students petitioned the state government to

adopt it.

• Paleontologists once thought stegosaurus walked on two legs, like T-rex.

However, most experts no longer believe this.

Triceratops

• Triceratops means “three-horned face” due to its hard, plated head that

held three spear-like horns.

• Triceratops was an herbivore, feeding only on the vegetation of western

North America.

• Triceratops was about 30 feet (9 m) long and 10 feet (3 m) tall, and

weighed 4–6 tons (3,600–5,400 kg). Triceratops could not move very

quickly despite having strong, thick limbs.

• Triceratops’ horns were a handy defense mechanism. When another

dinosaur such as T-rex attacked, triceratops would use its head and horns

as a battering ram similar to the rhinoceros.

• Triceratops was one of the last surviving dinosaurs approximately 65

million years ago.

Raptor

• Recent ndings conrm that the raptor was a feathered dinosaur. Raptors

likely had thick feathery coats, similar to a peacock’s, covering their scaly

skin.

• Despite their birdlike features, raptors could not y. Like tyrannosaurus

rex, they had short limbs that made liftoff impossible.

• Raptors had larger brains than most dinosaurs, making them one of the

most intelligent species.

• Raptors could run upright on two legs nearly as fast as an Olympic

sprinter—24 miles (38.6 km) an hour!

• Raptors preyed on other dinosaurs. Because of their speed, retractable

claws and sharp teeth, they were very effective hunters.

Discussion Starters

In addition to providing great opportunities for pretend play, Jumbo Dinosaurs

are helpful early science discussion starters. Ask questions, such as the

following, to help students understand the similarities and the differences

between the dinosaurs.

Could any of the dinosaurs ﬂy?

Did any of the dinosaurs have fur or hair covering their skin?

Did any of the dinosaurs lay eggs?

Did the coloring of any of the dinosaurs help it blend into its natural habitat?

Which dinosaurs were herbivores (plant eaters)?
