Now we are going to watch a clip about dinosaurs, if you have a question raise a silent finger. 

Nu gaan we een filmpje kijken over de dinosaurus, als je een vraag hebt steek je stil je vinger omhoog. 

Introducing the “Terrible Lizard”

One of the most fascinating creatures to ever roam the Earth was the dinosaur. You most likely have heard

of dinosaurs, seen pictures of them on TV or the Internet, or may have seen their bones in a museum.

Dinosaurs are an interesting group of animals that no longer exist, meaning they are extinct.

Dinosaurs evolved, meaning they changed, over millions of years. All animals change over time.

The word dinosaur was first used in 1842 by an English biologist (a person who studies life), Sir Richard

Owen. He needed a new word for a group of animals he identified and used the word Dinosauria. The word

comes from two other words that means terrible lizard. However, dinosaurs are not lizards but are reptiles.

Sometimes early birds were also referred to as dinosaurs.

Dinosaurs first lived over 200 million years ago but they died out about 66 million years ago. The time-period

they lived during is called the Mesozoic Era, which is also called the Age of Reptiles. The era is divided

into three smaller periods:

• Triassic: The earliest dinosaurs appeared, but they were small and walked on two legs. During this

period, an extinction took place and the period ended.

• Jurassic: The climate was hot and humid and there were many rainforests appearing. The

dinosaurs were the dominant (main) animals with backbones called vertebrates.

• Cretaceous: Dinosaurs continued to survive until another extinction took place. However, the flying

“dinosaurs” technically called birds, survived. The dinosaurs lasted about 170 million years.

By comparison, human beings have only lived for about 200,000 years on Earth. It is like people surviving

on Earth for 4 days, but dinosaurs living for almost one year.

The remains of dinosaurs have been found on every continent. This is because millions of years ago the

continents were joined together and there was one supercontinent called Pangaea. The dinosaurs easily

roamed the land moving from place to place because the oceans

did not separate the continents.

Once the continents separated, the oceans prevented dinosaurs

from moving between continents. Climates throughout the world

changed as well. The Earth began to cool and there was more

rain. During the last two periods of the Mesozoic Era, the land

separated to its present form today.

The dinosaurs’ extinction took place about 66 million years ago 75%

of all life on Earth died. There are many theories or guesses as to

what may have happened leading to the extinction. They include

worldwide volcanic eruptions, changes in the Earth’s climate, or

perhaps a meteorite from space smashing into the Earth.

 Reptiles: Reptiles usually cannot control their body temperatures and are called cold-blooded, but

a few of the dinosaurs may have been warm-blooded, as they could control their body temperature.

• Non-Flying: Most dinosaurs could not fly. On the other hand, many scientists believe birds evolved

from dinosaurs that could fly.

 

• Size: Dinosaurs ranged from small to huge. There was a chicken-sized dinosaur called compsognathus

to giant sauropods, such as the Titanosaurs, the biggest known dinosaur. In addition, some of them

had horns and others were covered in armor, an outer body protection.

• Survival: There were meat-eating, plant-eating, and omnivorous (both) dinosaurs. Some evolved to

have special diets and ate only insects or seeds. Dinosaurs lived in different habitats

• Living: Most dinosaurs were grazers, living off the land, traveling alone or in herds. Others were

predators, who hunted other animals.

Most of the information paleontologists (people who study dinosaurs) have learned about these interesting

creatures have come from studying fossils that are found in the ground. Scientists can re-create skeletons

of the dinosaurs, which can often be seen in museums.
