The geologic time scale shows the eras and periods of Earth's history. During the Jurassic period of the Mesozoic era, dinosaurs like T-Rex and Velociraptor lived. A meteor wiped out the dinosaurs and allowed mammals to evolve and dominate. Early humans were cavemen that evolved to become smarter and build the first civilizations. The document provides an overview of major events and periods within the geologic time scale.

TIME SCALE

2. THE GEOLOGIC TIME SCALE IS A
SCALE WHICH SHOWS ALL THE ERAS
AND PERIODS OF TIME.

3. HOW WOULD YOU LIKE TO MOVE
THROUGH SOME OF THE PERIODS
OF TIME? I’D LIKE TO. LET’S GO! ! !
! ! ! ! !  Let’s go

4. THE BEGINNING
 Long before the creation of anything there was only darkness.
 The Big Bang started out to be a big collection of energy.
 Then it blew up and created entire galaxies with the energy force
that has been in that orb for so long
 That was only the start of the Geologic time scale. Now I’m going
to take you to the Mesozoic, the Jurassic period to be exact.

5. THE JURASSIC PERIOD
 The Jurassic period is in the Era of the Mesozoic.
 Dinosaurs such as The T-Rex, Velociraptor, and Spinosaurus all
are predators of the Jurassic period
 Velociraptor’s started to grow feathers close to the end of the
Jurassic.
 A meteor wiped out all the dinosaurs, and mammals began to
take over.

6. DEATH OF THE DINOSAURS
 The Dinosaurs had walked the Earth for many years and left
mammals to remain small and weak until that fateful day of the
meteor.
 Towards the end of the Jurassic period, a meteorite hit Earth with
great force and blew a cloud of dust and debris into the atmosphere.
 This cloud caused all the plants to die because it blocked sunlight.
 The dead plants caused all the Herbivores to die because they didn’t
have any food to eat.
 The carnivores died because there was no more Herbivores to eat.
 The rise of the mammals has begun.

7. TAKEOVER OF THE MAMMALS
 After the death of the dinosaurs, mammals had a lot more free
space to evolve and grow into one huge population of species.
 Monkeys began to evolve into apes, which are the less evolved
forms of humans. Once they started to walk like normal human
beings, they were said to evolve into the first humans ever to walk
the Earth.

8. HUMANS BECOME THE
DOMINANT SPECIES!
The first people ever to walk the Earth were called Caveman.
When humans first started to walk the Earth, they couldn’t
communicate, couldn’t hunt, they didn’t even know how to draw yet.
But then evolution started to take place again and it evolved human
brains and made them smarter and they figured out how to hunt and
communicate and draw cave drawling's.

9. HUMANS BEGIN TO
BUILD CIVILIZATIONS
 When humans became smarter, they knew what they had to do in
order to survive. They began to build villages to keep shelter from
harsh weather.
 When humans became stronger and more intelligent, they built
bigger and more advanced cities.
 Human intelligence has evolved to the point that we’re able to
explore our universe, and we are even planning a manned
mission to Mars.

10. QUESTIONS
 What Era and period did the dinosaurs live?
 What began the extinction of the dinosaurs?
 How did humans become smart enough to build civilizations?
 Important: What is the Geologic time scale?

IS IT JUST
THE
BEGINNING?
