Dinosaurs: Giants of Patagonia Page #3

Flying reptiles reach their apogee

with the Quetzalcoatlus, the

pterosaur as wide as a small plane.

No flying bird will ever

get as big, not even close.

Apart from flight, this reptiles

has nothing in common with birds

And evolution gave it nothing to

survive the impending dramatic events.

Several factors could have

contributed to the demise of dinosaurs.

Mammals became bigger

and more competitive.

Drifting isolated continents

touched each other.

New rivalries appeared.

New diseases spread.

The climate was growing colder,

possibly because of

increased volcanic activity.

Five million years before

the end of the dinosaur era,

the volcanoes of the world

became much more active.

The air was

unbreathable in many places.

Vegetation suffered from the acid rain

and also from the

darkened and dust-filled skies.

But still, many

dinosaurs made it through

for a little while longer.

This comet is

as big as Mount Everest.

It covers the distance from

the moon to the Earth in two hours.

It cuts through our atmosphere

in two seconds.

It hit the earth near today's

Yucatan Peninsula in Mexico.

All the forest of North and

South America are destroyed by fire.

Already weakened, dinosaurs are

the animals that suffered most.

If they don't die as a result of the

impact and its immediate consequences,

they will die gradually in the aftermath.

In a relatively short time,

dinosaurs become history.

Or did they?

Not all the dinosaurs disappear.

Birds are dinosaurs.

It's difficult to imagine

how mammals could have evolved

alongside large dinosaurs.

If they haven't become extinct

maybe we just wouldn't be here.

Instead, when we

look at birds of today

it's as if the dinosaurs have left

us only the grace and beauty.

Palaeontology takes me fantastic

places all over the planet.

Still it keeps bringing

me back to my roots,

here in Patagonia.

More discoveries await me here perhaps

but as I move forward in life,

I find as much meaning

in sharing knowledge

as in discovering new dinosaurs.

This said, I'm not that old.
