“Jurassic Park” movies.

Well, never fear, Triassic and Cretaceous periods!
- 00:27
We still love you!
- 00:28
So the Triassic period started in…
- 00:30
…Oh, what?
- 00:31
…This video is supposed to be about the Jurassic Period…?
- 00:34
….Well…this is awkward.
- 00:35
Sorry, guys…maybe one day, you'll get a video…. [Dinosaur walking away]
- 00:38
The Jurassic Period began about two hundred and one million years ago, and lasted until [Coop pointing at a blackboard]
- 00:42
about one hundred and forty-five million year ago, so it's pretty darn old and went on for
- 00:47
a pretty darn long time.
- 00:50
Just like the grizzled old professors that like to talk about it. [Professor with grey beard and walking stick]
- 00:53
They're probably eye witness accounts.
- 00:55
The Earth had calmed down a lot in the Jurassic Period.
- 00:58
It was moist, stable, and warm, and its air was no longer poisonous.
- 01:02
Always a plus.
- 01:03
Basically, it was finally out of its hormonal teenage years. [The Earth with long side swept hair and sunglasses]
- 01:07
And that whole, "no longer poisonous" thing was a big plus, especially for all the creatures
- 01:11
that lived back then.
- 01:12
Instead of poison, the air was filled with life-supporting oxygen.
- 01:16
Which…y'know, is always a good thing.
- 01:19
And of course, there was also plenty of water to support life on land, at sea, and in rivers [Rainbow over a river]
- 01:23
and lakes.
- 01:24
Sounds pretty nice, huh?
- 01:26
And since there was all this great water, sun, and air, the Earth was covered in lush [Land covered in plants]
- 01:30
vegetation.
- 01:31
And this vegetation proved to be great food for many herbivores, including many dinosaurs
- 01:35
and early small mammals.
- 01:37
These herbivores thrived off of the large amounts of vegetation.
- 01:40
And you know what happens when herbivores thrive? [Rabbit next to a carrot]
- 01:42
Carnivores thrive, too.
- 01:44
Because a carnivores favorite meal is, well, a herbivore. [The dinosaur eats the bunny]
- 01:48
We hear it was the top selling item in Jurassic McDonald's. [McDonald's made of straw]
- 01:51
Some of the most well-known animals that lived during the Jurassic Period include...
- 01:55
the Archaeopteryx...
- 01:57
Allosaurus...
- 01:58
Brachiosaurus... [Pictures of the animals]
- 02:00
Ichthyosaurus...
- 02:02
Plesiosaurus...
- 02:03
Large dragonflies...
- 02:05
Crocodiles...
- 02:07
and the Anklyosaurus. [Dinosaur with human ankles stuck to it's back]
- 02:08
Which as literally all ankles.
- 02:10
Just kidding.
- 02:11
They actually looked like this.
- 02:13
And these are just a few of over 800 different types of fossils of ancient Dinosaurs that
- 02:18
scientists have discovered from this period.
- 02:20
And no, before you ask, your Great Aunt Margaret is not one of them. [Angry looking aunt]
- 02:24
Though…that is a pretty funny joke.
- 02:26
High five. [Boy is high-fived through a window]
