1. The Age of
The Dinosaurs

2. Millions of years ago, Great beasts called "dinosaurs" thundered
over the earth.
Yet up until the last
century, when the
first dinosaur fossils
were discovered, no
one even imagined
such animals existed.

3. Dinosaurs Before there were any people there were dinosaurs.
Dinosaurs were one of several kinds of prehistoric reptiles that lived during the Mesozoic Era the “Age of the Reptiles”

4. The name dinosaur comes from the term Dinosauria, which means terrible lizards.

5. Dinosaur is the name of a group of prehistoric reptiles that ruled the earth about 160 million years ago.
These animals died out millions of years ago, but they have fascinated people ever since they were first described in the early 1800’s.

6. Kinds of Dinosaurs
Dinosaurs varied greatly in how big they grew, how they looked, and where they lived. Some of the most famous were such gigantic animals as Apatosaurus (uh pat uh SAWR uhs), Diplodocus (duh PLAHD uh kuhs), and Tyrannosaurus (tih ran uh SAWR uhs). Apatosaurus (formerly called Brontosaurus) grew about 70 feet (21 meters) long. Diplodocus reached an even greater length -- about 90 feet (27 meters).  

7. Allosaurus
Do you know
what the
Utah State
Fossil is?

8. The allosaurus was designated
The Utah State Fossil: The Allosaurus
The allosaurus was designated
the State Fossil in More allosaurus specimens have been found in two of Utah's quarries than any other dinosaur. Sixty individuals, from
juveniles to adults, were found
at one site in Utah.

9. Big Al Nickname: Different Lizard
Age: million years ago during the late Jurassic Period
Size: feet long (as long as two big Python snakes!)
Weight: Anywhere from 2 tons to over 5 tons
Characteristics: Sharp claws up to 6 inches long. Teeth up to almost 4 inches long
Special Talents: Super smart compared to other dinosaurs. Extremely fierce. Known to attack other dinos twice his size.

10. Where Dinosaurs Lived See the world as it looked during
the Jurassic Period!

11. The Jurassic climate was warm
The Air was damp, like a tropical forest

12. Paleontology
Paleontology (PAY lee ahn TAHL uh jee), is the study of animals, plants, and other organisms that lived in prehistoric times (more than 5,500 years ago). Fossil remains of organisms occur in layers of sedimentary rocks (rocks formed when mineral matter settled out of air, ice, or water). The organisms that are now fossils were alive when the rocks were being formed. They were buried and preserved as the layers of rock piled up.

13. So what do you think a Paleontologist is?
is a scientist
who studies
paleontology,
learning about
the forms of life
that existed in
former geologic
periods, chiefly by
studying fossils.

14. Fossils are the reason we have most of this information
Fossils are the reason we have most of this information. For almost 200 years, paleontologists have been discovering fossils all over the world. They’ve identified more than 330 different kinds of dinosaur fossils. And every year, they find new fossils. These fossils can tell us how big an animal grew, what it ate, even how it died.  

15. Dinosaur National Monument
Utah/Colorado
A stony frieze at one of the continent’s largest
and richest dinosaur quarries holds the bones of
beasts that ruled the Jurassic: stegosaurs,
allosaurs, apatosaurs and many more.

16. The first dinosaur to be described
scientifically was Megalosaurus
in 1824, by William Buckland.
Buckland ( ) was a
Britishfossil hunter and
clergyman who discovered
some Megalosaurus fossils in
1819 and named the reptile
in It was the first dinosaur
ever described scientifically and
first theropod dinosaur discovered
(this is all in hindsight, because the dinosaurs had not yet been
recognized as a separate taxonomic group - the word dinosaur
hadn't even been invented yet).

17. Megalosaurus

18. Did They Have Colors?
It is very difficult to figure out how the dinosaurs sounded, how they behaved, or what color they were.

19. Plant-Eaters Triceratops Herbivores
Most dinosaurs were plant-eaters like:
Triceratops
What do we call plant-eaters?
Herbivores

20. Meat-Eaters T-Rex Carnivores Some were meat-eaters like:
What do we call meat-eaters?
Carnivores

23. The Food Chain Meat-eating animals (carnivores like Tyrannosaurus rex)
get their energy by eating other animals, mostly plant-eating
animals (herbivores like Triceratops). The herbivores
get their energy by eating plants (like cycads).

24. Where Did Everybody Go? You may have noticed that there
are no dinosaurs
around these days.
In fact, there haven't
been any around for
about 66 million
years.

30. Well, we don’t know the real absolute theory of how they became extinct, but----
One thing for sure is……….
We will have an incredible time going back in time to learn about these marvelous creatures.
