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