No cell phones, electricity or even other humans.

Wait dinosaurs are here?

Okay, maybe this won't be so bad.

The world was pretty different during the late Triassic period.

One of the most notable differences is this thing right here.

This is Pangea, a supercontinent containing different parts of today's world.

There's Australia down South, North America in the North West and

Eurasia in the East, all interconnected.

It would take you a while, but in theory, you could walk from California to France.

But you won't see the Hollywood Walk of Fame or the Eiffel Tower as they don't exist yet.

What would you see?

The first thing you'd notice as you're traveling across Pangea

are all the dinosaurs running about.

You won't have to worry about dinosaurs such as the dilong,

that weigh only 11 kg (25 pounds,) they won't pose much of a threat.

But watch out for the Melanorosaurus who has a height of 12 meters (39 feet)

and would find you to be a tasty snack.

Scientists say the late Triassic period was the dawn of the first dinosaurs.

Dinosaurs of all sizes would be everywhere.

You'd also see some other crazy creatures you've never seen before,

and some that may remind you of animals you see today.

This species known as Drepanosaurus with its reptile-like skin and arched back

might be one of the first versions of birds to ever exist.

The Triassic period was an incredibly important 50 million years of evolution.

A time with not a lot of competition between species, since just prior this period,

70% of the Earth's creatures were wiped out in a mass extinction event.

Many of the animals at this time were able to thrive and grow

without having to be constantly wary of other predators.

The further you travel inland into Pangea you'll notice the massive weather changes.

The outer edges of the supercontinent may be full of lush forests and green grass,

but the further you go in, that begins to change.

Scientists suspect that much of Pangea was a dry, desert wasteland.

That's because the land mass was so large

that the interior wouldn't have received the cooling effects of the ocean.

Speaking of which, the ocean, known as Panthalassa

surrounded all of Pangea and covered 70% of the Earth's surface.

This ocean was extremely deadly.

It would easily produce superhurricanes and monsoons. And due to its massive size,

they could gain enough momentum to hit Pangea with potentially fatal weather.

Pangea was just beginning to separate 200 million years ago.

If you were able to stick around a few million years for the Jurassic period,

that's when you'd truly see the dinosaurs thrive.

The T-rex, brachiosaurus, stegosaurus,

What would happen if they were still alive today?

That sounds like a question for another WHAT IF.
