This is a presentation on dinosaurs by a 5th grader (years ago back then), Indra Cipta Putra Mandiri, in front of a bunch of the highest level students in their presentation session class

1. The most fearsome
dinosaurs in the World

2. 1.The fearsome dinosaurs
There are lots of types of
dinosaurs, and some of
them are one of the
most ferocious meat-eating
dinosaurs, such
as:
1. Coeloephysis
2. Allosaurus
3. Tyrannosaurus rex / t-rex
4. Nanotyarannus

3. 2.Time period
There are three periods in
mesozoic age:
-Triassic
-Jurassic
-Cretaceous
Some dinosaurs did not live in the
same period.
Coelophysis=triassic
Allosaurus=late jurassic
T-rex=late cretaceous
Nanotyrannus=mid cretaceous

4. 3. Dinosaur extinction
The dinosaurs were extinct about 50-65 million years ago, and here’s
what happened:
1. Because of the sour rain, all the plants became poisonous.
2. The herbivores were dead because they were poisoned after eating
the poisonous plants.
3. Because the herbivores were dead, the carnivores would no longer
live
This is what scientists think about the extinction but, no one knows For
sure UNTIL TODAY…………..

5. 4.Dinosaur fossils
Dead dinosaur body is buried
underground, and their bones
will be fossilized and found by
the scientists; then the bones
will be displayed in the
museum.
