Dinosaurs lived on earth
more than 215 million years
ago
They lived in most parts of
the world
They ruled the earth for
nearly 150 million years
Dinosaurs have been extinct
for 65 million years
Extinct – something that
once alive but no longer
exist anywhere on the
earth

3. How Do We Know About
Dinosaurs?



Paleontologist – scientist who studies fossils
Fossil – what is left of a plant or animal that lived
long ago
Dinosaur – animal that lived millions of years ago
Dinosaurs were not lizards or reptiles but many did lay eggs. Some had skin
like crocodiles while others skin was much smoother.

4. How a Dinosaur Fossil is Made?
Step 1:
Step 2:
A dinosaur lives on Earth
and roams the land.
A dinosaur dies and its
body lays on the land.
Step 3:
Step 4:
Over time wind and rain
help to cover the
dinosaurs body with mud,
sand, and leaves.
After millions of years
the mud, sand, and leaves
turn to rock. The bones
or shape of the dinosaurs
body are left in the rock

5. How do Scientist Get Fossils?





Paleontologist use special tools and chip fossils carefully from
rocks
The fossils are then taken to a museum where they are cleaned,
measured, and studied.
Most fossils are found in pieces
Scientist try to put the fossil pieces together.
Reconstruct – to rebuild or put together like puzzle pieces

Paleontologist give each dinosaur a name that best
describes it.
STEGASAURUS:
