Long, long ago, dinosaurs used to roam the
Earth. What happened to them and where did
they go?
230 million years ago, dinosaurs existed during
the Mesozoic Era.
The dinosaurs lived in a beautiful habitat,
and were the rulers of their animal life.
However, one day the dinosaurs became extinct.
Extinction is what happens when a species
of an animal dies out completely.
We know for sure that dinosaurs were once
here because they left behind their bones!
People called paleontologists find and dig
up these bones, and then piece them together
like a puzzle to put in museums!
The first theory scientists believe is that
the dinosaurs died from the Ice Age!
The Ice Age was when ice covered the Earth,
making the dinosaurs die because they were
so cold!
The second theory scientists have is that
the dinosaurs died from a volcano erupting!
The lava from the volcano burned everywhere,
and killed the dinosaurs in its way.
The third idea is the most believable. Scientists
think that the dinosaurs were killed from
a big explosion from a meteor!
A meteor is a big rock from space, that falls
and hits the Earth!
This meteor came in so fast, that it left
a big hole in the ground called a crater.
The meteor made a big explosion when it hit,
and killed off all the dinosaurs and life!
Without the dinos or other animals, everything
died off. The land became unlivable.
We now only remember and see dinosaurs in
museums.
But can you imagine if dinosaurs were still
here? A T-Rex skeleton is 10x bigger than
a car!
The dinosaurs would be too big for us to live
together, and scary too!
Maybe it is a good thing they don’t exist
anymore. They’re cool to look at, but not
to live with!
